Rational Oven Error Codes Explained

In any sophisticated appliance, and in Rational ovens specifically, error codes are one of the most helpful things to learn what issue this unit is encountering now. However, error codes vary significantly between manufacturers and even between different appliance models. So, to understand what’s happened to your exact appliance, you need to know the error codes of this exact manufacturer.
Rational oven error codes explained
In this post, we will explain a few Rational oven error codes, which are flashing in the kitchens of our customers most frequently.

iCombi Pro Error Codes

When it comes to the iCombi Pro (or the SelfCooking Center as its older version), the common issues are related to CleanJet® and humidity control. At LE Company, we classify the Service 25 and Service 30 as the most common error codes our customers encounter with their SelfCooking Centers.
However, sometimes, gas issues also occur. Please note, if you ever need our help, you can always visit our Rational oven repair page and send us your request.

Service 25

The Service 25 error code appears when the CleanJet® fails to function correctly. Typically, this error code flashes during the cycle and indicates there may be an issue with a water supply, filter or some blockage that you can fix yourself.

If you are facing Service 25 but can’t fix the issue yourself, you can continue using the appliance, but only for limited runs. Avoid heavy or prolonged use until the fault is rectified.

Service 30

The Service 30 error code appears when there is some issue with humidity control. If you are facing this error code, no DIY fixes are possible unless you are an engineer with expertise in Rational ovens. The cause here is a faulty humidity or temperature sensor, which may be defective or require calibration. Only a professional has both knowledge ad tools to handle the task.

Note, with Service 30 error code, it is possible to continue using the unit for cooking, but only to a limited extent.

Service 32

The Service 32 error code indicates unsuccessful ignition and appears when there is a problem with the gas system. Please note, if you see this error code, stop using the appliance, shut off the gas tap, and contact the Customer Service Center or professional Gas-Safe engineers immediately.

If you need emergency Rational oven repair in London, you can count on us – we are on the Gas Safe Register and can resolve any fault safely and efficiently.
Can you use your Rational oven. Errors explained
A simple guide on the Rational oven errors. Know when you can still use your oven or when you MUST stop using it.

VarioCooking Center Error Codes

When it comes to the VarioCooking Center, the common issues are related to core temperature probe, pan valve drive, or cover drive system. At LE Company, we classify the Service 100 (Service 101), Service 230 (Service 231) and Service 252 as the most common error codes our customers encounter with their VarioCooking Centers.

Service 100 (Service 101)

The Service 100 (or Service 101) error code appears when there is an issue with the core temperature probe. The Service 100 error code indicates there is an issue with the temperature probe for left-hand pan. The Service 101 error code indicates there is an issue with the temperature probe for right-hand pan.

With the Service 100 or Service 101 error codes, you can still use the right-hand pan or the left-hand pan of the appliance, respectively.

However, as using just one pan halves the unit’s output, we recommend arranging a repair without delay. The cause here is the faulty left / right pan core temperature probe. Here, there are no user-serviceable solutions – it is a job for an expert with proper knowledge and tools.

Service 230 (Service 231)

The Service 230 (or Service 231) error code appears when there is an issue with the pan valve drive. These error codes indicate, respectively, an issue with the left-hand or right-hand valve drive.

If you see Service 230 or Service 231 error code flashing, you can still use another pan without any limitation – the right-hand pan or the left-hand pan, respectively.

However, as running in single-pan mode negatively affects your kitchen capacity, we recommend fixing the issue as soon as possible. Typically, the cause here is the faulty left / right pan valve drive, which needs replacement. Such replacement is not a DIY task but a job for an expert.

Service 252

The error code Service 252 appears when there is an issue with the cover drive system. Typically, the problem affects both right-hand and left-hand pans. So, no further usage is possible until an engineer fixes the issue.

The nature of the Service 252 error code is highly complicated and always requires professional attention. Here is just some of the most likely causes we at LE Company have already dealt with:
  • Faulty potentiometer,
  • Problem with the power supply to the control boards
  • Loose connection between the control boards
  • Problem with limit switches, etc.

Conclusion

For some errors, you can clear the code with the arrow button and continue using the unit, though there are still some limitations on its usage. However, for some other codes (especially for the codes that indicate gas issues), stop using the appliance until an expert fixes the issue.

Here, we listed just a few Rational oven error codes you may face. If you are facing some other error code, do not hesitate to contact us to learn what issue it indicates.

Start preparing your BBQ for the summer season

Start preparing your BBQ for the summer season

Although there are still a few months until summer, it is high time to think about preparing your BBQ for the summer season. In short, we recommend breaking the process down into a few key steps – thorough inspection, deep cleaning, and oiling as finishing touches before your first grill.

Thorough inspection

Safety is king. Therefore, it's crucial first to make sure your grill is safe to use. To ensure this, inspect your BBQ, both the exterior and under the hood, for possible fire hazards:
  • Web or insect nests
  • Grease buildup
  • BBQ damage or worn-out parts

In case you find any of the mentioned issues, clean the appliance or repair it, what is applicable. 

If you have a gas BBQ, take a few extra steps to detect issues with its gas system:
  • Inspect the hoses for cracks
  • Check for tight connections
  • Test for gas leaks
  • Test the ignition

In case you find any of the issues, contact our Gas Safe engineer to fix it. If you do not have enough expertise to undertake gas-safety assessment, turn to us.

In some cases it is very easy to clean your bbq or grill appliance, however we still recommend to turn to a professional company for that job, so your appliance serve you longer. For more information visit any of these two pages: grill repair page or barbecue repair service.

Deep cleaning

Deep cleaning is not only about your safety but about the appliance performance and your future cookout taste.

Here is a brief guide on what your BBQ cleaning activities should include:
  • Removing old ashes from the bottom of the bowl
  • Soaking and scrubbing the grates
  • Cleaning the burner (for gas grills)
  • Cleaning or replacing the grease tray (if any)
  • Clean the exterior, including the lid and control knobs

For cleaning, use soapy water or a non-abrasive cleaner, applicable for your type of grill.

BBQ and Grill brands we can help you with

Twin Eagles Grill Repair
Wolf Grill Repair
AGA Grill Repair
BeefEater Grill Repair

Grate oiling

To prevent your BBQ and grates from excessive rusting, do not neglect their oiling. To clarify, oiling creates a non-stick surface and helps prevent rust. 

For oiling, apply high-heat cooking oil (for example, grapeseed or vegetable oil) on the grates, the insides of the cookbox and even the lid. Then, close the lid and run your BBQ at high heat for 20-30 minutes. This burns off excess oil and creates a polymerised surface on your BBQ components. As a result, food won't stick to your BBQ grates or cookbox. Besides, the polymerised oil creates a good barrier against rust.

So, by taking all these steps to prepare your grill for the summer season, you will get a safe, well-running appliance and can enjoy delicious cookouts without any hassle.

Most popular coffee machine brands we deal with

Every year, we service hundreds of coffee machines in London. This gives us unique insight into the models that are most popular in London homes, offices, cafes, and restaurants.

In this article, we highlight the most common domestic and commercial coffee machine brands we have ever dealt with.

Most popular domestic coffee machine brands

De'Longhi

Based on our experience, De'Longhi is a household favourite. These coffee machines are renowned for their user-friendly automation and great performance. With integrated grinders and one-touch drink programmes, their Magnifica and Dinamica series offer bean-to-cup convenience. To know more about how we can help you with your De'Longhi coffee machine visit our De'Longhi repair page.

Sage

Sage offers bean-to-cup models and is highly valued by high-end Londoners for bringing barista-level control into homes. Models like the Barista Express and Oracle offer dose control, precise temperature settings, and low-pressure pre-infusion. Another standout feature is the automated steam wand that enables the user to get perfectly textured milk. Visit our main Sage coffee machine repair page to know more.

Nespresso

Due to the patented capsule technology, these coffeemakers are the champions of speed and consistency. One of their most convenient features is a closed system, which means less internal cleaning for the user. Models like Vertuo use barcode-reading for automatic drink sizing and spin-brewing to create a rich crema.

Smeg

Smeg stylish espresso machines are the popular choice for those who prioritise iconic design and aesthetics. Their ECF series offers a semi-automatic experience, pairing 1950s-inspired style with features like a pressure gauge and a commercial-style steam wand.

Most popular commercial coffee machine brands

La Marzocco

These traditional espresso machines with outstanding performance are a common choice for speciality coffee shops. They are considered as the gold standard, especially in the speciality coffee sector. The range can cover all needs, starting from Linea Classic/PB for high-volume operations of busy cafés and restaurants and ending with GS3, a compact, high-end single-group machine perfect for smaller venues or businesses wanting top quality in a smaller space.

Rancilio

Rancilio is one of the major players in the UK foodservice sector. Known for durability, ease of use, and features like the Xcelsius temperature control and Easyclean self-cleaning function, these espresso machines are ideal for high-volume restaurants that need consistent performance and models that can adapt to different cup sizes (for example, tall cup versions for takeaway). Visit our Rancilio repair page to get more information about it.

La Pavoni

These coffee machines are best suited for busy, high-end venues that require barista-grade results with streamlined, automated operation and high-volume capacity. For example, its Desiderio 3, features a large boiler, precise PID temperature control, and a user-friendly touch screen.

So, to conclude, the popularity of domestic coffee machines is driven by their ability to brew a truly flavoured beverage paired with a blend of convenience, innovation, and style. For commercial espresso makers, popularity comes from their robust engineering (which means great endurance), high-volumes, and consistent performance even during a huge number of shots in a row.

At LE Company, we are happy to help you with any domestic or commercial coffee brewing appliances. Whether you need help with repairs or professional maintenance, you can count on us.

DIY: Regular appliances check-up list by LE Company

DIY: Regular appliances check-up list by LE Company

Just as it is wise to have regular personal health check-ups, it is equally recommended to provide your appliances with regular maintenance. To clarify, well-maintained appliances last much longer than neglected ones.

As an engineering company with vast experience, we have seen plenty of proof for this. That is why we created a regular check-up list, categorised by appliances.

Oven, stove, cook top

For cooking appliances, while some maintenance activities are general, others may differ if the unit is gas powered.

For general maintenance:
  • Clean the cooktop or stovetop surface and oven interior
  • Run the self-clean cycle (for ovens, if available)
  • Check oven door seals
  • Check temperature accuracy

For gas units:
  • Check burners for food debris and build-ups, clean if necessary
  • Check flame indicator – it should be blue
  • Test igniters – they should spark quickly.

Fridge and freezer

Regular fridge and freezer maintenance splits into two task groups. The first aims to keep the unit efficiency at its peak. The second ensures your food stays safe.

For efficiency considerations:
  • Clean condenser coils
  • Check door seals for tightness
  • Check temperature settings
  • Check for ice buildup, defrost if necessary

For food safety considerations:
  • Check goods for expired items and get rid of them, if any
  • Clean the interior
  • Check the drain hole, clean it, if necessary

Dishwashers

Dishwasher maintenance prioritises performance considerations while also addressing preventative care. So, to keep its washing efficiency at its top and prevent minor issues from becoming major repairs, follow the check-up list below:
  • Check and clean the filter
  • Inspect door gaskets
  • Check spray arms holes for limescale clogs, clean and descale, if necessary

Coffee Machine

While also considering system longevity, coffee machine maintenance focuses on protecting the espresso flavour. Therefore, consistent care should include:
  • Descaling the water tank
  • Cleaning the brew group
  • Cleaning the steam wand after each use
  • Replacing water filters as recommended

Range hood

Range hood maintenance should ensure functional effectiveness, fire safety, and clean surfaces. Here is a check-up list that addresses these key points:
  • Clean or replace grease filters, what is applicable
  • Check exterior vent flap for free opening and closing (for ducted hoods)
  • Wipe the exterior surface

Conclusion

Regular maintenance not only prevents many appliance issues but also helps you keep your kitchen clean and functional. While most of the listed activities are for monthly or semi-annual checks, basic cleaning should be part of your daily routine. So, make it a habit to degrease and wipe down your cooktop or stovetop after every use and clean your oven interior in case of spills. Also, wipe up any spills on fridge shelves immediately as you find them out.

How to choose the best barbeque in 2026

When choosing your best barbeque, your decision factors should include your BBQ priorities, cooking style, storage needs budget for upfront (purchase) and running costs.

Types of grills

Before diving into the question of how to choose the best barbeque, let’s discuss the grill range itself. Below we describe existing types of grilling appliances:
  • Charcoal grills – Use charcoal. Made from steel. Relatively lightweight. Provides a classic, smoky flavour. Offer the ritual of lighting and managing the fire as a part of the experience. Require minimal grill repair
  • Gas grills – Use gas. Made from steel. Relatively lightweight. Start instantly, heats evenly, offers precise temperature control
  • Pellet grills – Use wood pellets. Made from steel. Relatively lightweight. Provides a classic, smoky flavour. Can operate like an outdoor oven.
  • Kamado grills – Use charcoal. Made from ceramic. Heavy. Retains heat superbly. Can operate like an outdoor oven.
  • Electric grills – Use electricity. Made from steel. Relatively lightweight. Has no open flame. Start and heats quickly.

Consider your BBQ priorities

When taking into account BBQ priorities, there could be the following options:
  • For quick results, convenience, top control, and easy cleaning – gas or electric grill
  • For authentic smoky flavour and traditional ritual – charcoal, pellet, or kamado grill
  • For maximum versatility (grilling, roasting, and baking) – pellet or kamado grill
  • For using in enclosed spaces – electric grill

Consider your cooking style

When considering your cooking style, there could be the following options:
  • To enjoy the ritual – charcoal or kamado grill
  • To get the food with minimal effort – gas or electric grill

Consider storage needs

When taking into account storage needs, there could be the following options:
  • No need to store it away – any type of grill (a protective cover is recommended)
  • Need to store it away – electric and small gas grill (lightweight, foldable, or with wheels)

Consider upfront and running costs

When considering upfront and running costs, there could be the following options:
  • Focus on low upfront costs – charcoal kettles and electric grill
  • Focus on low running costs – gas grill
  • If premium price and high running costs are affordable – pellet and kamado grill
Note that after choosing the most suitable barbeque type, consider the grilling capacity of the unit (grill size) measured in square inches of cooking area. The size should fit your number of people you usually cook for. However, you may need to compromise on the barbeque size if you have space restraints.

Top domestic ovens in 2026 by LEC rating

At LE Company, we possess unique insight into the ovens London homes choose for their kitchens. The 2025 top we present now is not a traditional "best-of" list. It is a brand performance ranking based on how often we install, service, or see these brands in client projects, correlated to their reliability according to repair frequency.

Gaggenau

Gaggenau ovens are a common choice for those who appreciate a professional minimalist look combined with cutting-edge technology. While we install, service, and see a lot of Gaggenau ovens in the kitchens of our customers, we receive far fewer requests for Gaggenau repairs in London. And this is the best proof of the high reliability and durability the brand provides.

La Cornue

La Cornue ovens are less common than Gaggenau due to their custom nature. However, they are unmatched in perceived value and artisanal craftsmanship. These ovens are an excellent choice for those who want to enjoy the ultimate bespoke statement in their kitchens. Indeed, the manufacturer creates a unique, heirloom-quality centerpiece that defines the entire kitchen.

Miele

Miele ovens are the benchmark for smart homes and are highly valued by those who prefer the extra benefits that remote control provides. Indeed, the manufacturer offers the innovative suite of connected kitchen appliances backed by proven durability. However, we often see Miele ovens even in homes that do not utilize smart home integration. Such a choice their owners explain by the trust that the brand creates due to the long-term performance of its ovens and after-sales service.

Lacanche

Lacanche ovens are an ideal choice for those who are looking for a truly authentic cooking experience. Designed as commercial-grade cooking equipment that homes can utilise and enjoy, these ovens offer French professional chef heritage. Due to the material quality, which stainless steel, brass, and cast iron feature, these ovens feature great reliability and longevity.

So, as we can conclude based on our experience, ovens of premium brands such as Gaggenau, La Cornue, Miele, and Lacanche are the tops when it comes to reliability, longevity, authentic cooking experience or bespoke artistry and heritage.

How to choose a good Air Conditioner in 2026

How to choose a good Air Conditioner in 2026

Now, everyone knows that a good air conditioner is one that has got the correct sizing. In other words, the unit should meet your needs and be sufficient for the square metres it is to cool. This is about a BTU/kW ratio.

Also, it is widely known that a good air conditioner is one that features high energy efficiency (A+ and better) and a long-term lifespan. So you do not need to spend tons of money on cooling or air con repair.

But for those who live in the UK in general, and especially in London, it’s worth considering some other factors.

Choose the right AC system

Your property type may determine the possible air conditioning type. Also, consider whether planning permission is required and whether you can get it.

Here are examples of recommended options for different premises:
  • For standalone houses – multi-split or ducted systems
  • For listed buildings or conservation areas – fully internal water-cooled systems
  • For flats – fully internal systems (all-in-one monoblocs, water-cooled, or portable AC)

To clarify, modern flats or premises in listed buildings or conservation areas may have leaseholder restrictions on external units and lack outdoor space. For installation of split systems in flats, you may first need to get planning permission from the building management company or leaseholder. Installation of systems with an external unit in a listed building may involve getting consent from your local planning authority. All this makes fully internal water-cooled AC systems a better option.

Choose a quiet, dual-capability unit

For any premises, and especially for studios and other compact flats, it is wise to consider how many dB an AC unit produces. To clarify, compact flats are highly sensitive to noise, and loud air conditioner can make you feel very uneasy instead of comfortable. So, choose a unit with quiet operation – for example, within 27-34dB.

Another important factor to consider is cooling/heating capability of the unit. In the UK, and in London especially, specific climate conditions make both cooling and heating features demanded. In other words, a good air conditioner is one that can provide you with a year-round comfort, both when it is hot and cold outside.

In conclusion, to choose a good air conditioner, consider its sizing, energy efficiency, lifespan, type, noise level, and dual heating/cooling capability.

Why restaurants and cafes choose La Marzocco

In this article, we will explore the key factors why restaurants and cafes choose La Marzocco. We will discuss the operational benefits, ultimate performance, and efficient workflow these espresso machines ensure.

Operational benefits

La Marzocco, with its elaborate engineering and craftsman philosophy, offers a wide range of operational benefits:
  • Utmost durability
  • Longer service intervals

All these are the result of using higher-grade materials for boilers, critical plumbing, frame, and chassis constructions – marine-grade brass and fully welded stainless steel.

For example, some other brands may use a combination of welded and bolted assemblies or lighter-gauge materials and, thus, face greater risks of getting out of order and more frequent descaling and maintenance. Indeed, La Marzocco repairs are one of the less frequent among other coffee machine brands.

Ultimate performance of the unit

When ordering coffee, restaurant customers expect to be serviced with the perfect shots. And this is what La Marzocco espresso machines help deliver. Every time. For every shot.

Such great consistency becomes possible by exceptional temperature stability, achieved through:
  • Dual-boiler engineering, which eliminates temperature fluctuation in general
  • PID temperature control, which ensures precise temperature required for the perfect shot
  • Pressure profiling and pre-infusion settings for advanced extraction control

Barista workflow efficiency

In addition to flavour expectations, customers want quick service. La Marzocco understands this and helps maximise barista workflow efficiency.

Features like straight-in portafilters, Auto Brew Ratio or Auto Volumetric configurations can significantly speed up the service, compared to fully manual brewing. This helps baristas work faster and more comfortably. In a busy rush, for example, in mornings, this is essential for a coffee shop in every venue.

So, to sum up, restaurants and cafés choose La Marzocco for its reliability and longevity, shot-to-shot consistency, and coffee service speed-up. Taken together, all this makes the La Marzocco espresso machines a sound business investment. 

In case if your coffee machine has some faults feel free to contact LEC engineering company at any time!

Why SAGE coffee machines are that good

Why SAGE coffee machines are that good

In short, Sage coffee machines are that good for their robust engineering, thoughtful brewing philosophy, and a suite of helpful features integrated in some of the models.

Robust engineering

Based on our experience, requests for Sage repairs are far less frequent compared with many other brands. And indeed, when properly used and maintained, these coffee machines are engineered to last for years.

The component and engineering quality allows the machine to handle continuous brewing of 2-3 cups with a low risk of overheating and component failure. We know of cases when a Sage coffee machine has delivered up to 8 cups of coffee a day without a single failure for about six years.

Thoughtful brewing philosophy

When it comes to brewing philosophy, it encompasses five key aspects:
  • Grinding
  • Dosing
  • Tamping
  • Extraction
  • Milk texturing

And this is where Sage comes as a true expert and faithful assistant. For example, most of the models in the Sage range are equipped with a built-in grinder, which ensures the ideal coarseness of the coffee grounds. Then, automated models enable precise dosing and tamping, so you do not have to worry about these tricky steps.

Moreover, the Sage features a sophisticated digital temperature control system that ensures the temperature stability during extraction. As for milk texturing, whether you have a model with a manual steam wand or an automated system, with the Sage it is easy to get silky microfoam, even with alternative milks.

Great and helpful features

One of the Sage’s advanced features that help you ensure excellent brewing results is a dual boiler system. With separate boilers for brewing and steaming, you can enjoy speed for multiple drinks and stable perfect temperatures.

Another compelling feature in the Sage range is the ThermoJet™ heater. With this technology, you get the ideal brewing temperature in just 3 seconds instead of waiting almost a minute with a standard thermocoil system.

So, to sum up, with Sage, it is easy to get your most flavourful espresso and create silky microfoam even with little to no experience while still retaining barista-level control. Combine this ease of use with the machines' proven longevity, and you will see that Sage coffee machines are not just good – they are truly outstanding.

Why people choose Sub-Zero fridges

In short, people choose Sub-Zero fridges for their rich food preservation features, stylish design and architecture, and long-lasting engineering with little to no need for Sub-Zero repairs.

But let’s be more specific.

Food preservation

Sub-Zero helps food last much longer, compared to many other fridges. This superior food preservation is the result of at least three features the appliance is equipped with:
  • Dual refrigeration with precise temperature control
  • Precise humidity control
  • Unique air purification

To clarify, separate refrigeration and freezing cavities prevent air or flavour migration. Individual evaporators for each storage zone ensure humidity sufficient for the storage purpose in these exact zones. Finally, one of the greatest features of the appliance is unique filters that destroy ethylene gas and bacteria to prolong food lifespan.

Design and architecture

Sub-Zero astonishes with its luxury, professional-looking design, distinguishing itself from many other brands, including even luxury ones. Its commercial-grade stainless steel and appealing glass fronts especially add the status and paramount aesthetics to a kitchen.

Besides its status-appealing exterior, people choose Sub-Zero fridges for their elaborate storage orchestration. Individual compartments in the freezer section, dedicated zones in the fridge section – all this eliminates the need to dig through a mountain of goods and helps the owners actually see and use what they have.

Long-lasting engineering

Sub-Zero fridges are built to last. While, on average, many other fridges in the luxury segment can run for 10-15 years, Sub-Zero can run without a single failure for 20-25 years.

Moreover, this exciting durability is proven with a longer-than-average warranty. For example, in the UK, the manufacturer offers a comprehensive 12-year product protection plan, which proves in itself how confident the manufacturer is in these appliances.

So, to sum up, people choose Sub-Zero fridges because the brand ensures status and appealing look, less food waste, and greater savings on repairs in the long run.

Why You Should Avoid Air Con Steam Cleaning

Why You Should Avoid Air Con Steam Cleaning

Air con cleaning is a highly important service that is required on the regular basis. Cleaned air con is your guarantee of the fresh air circulation at home or your workplace. In order to get more clients some cleaning companies started offering pressure steam cleaning that costs cheaper and saves the engineers about 15 minuts comparing to the regular cleaning. Yes, it is fast, but this is the service we strongly recommend to AVOID.
The main reasons are two:
- Dust collects in clumps and remains on the blades
- The clumps affect the way that blades spin and make the noise
That is why we recommend to perform the "old fashioned" way of cleaning that will definitely give you the desired result rather than paying slightly less, win 15 extra minutes but make the issue even worse.
Here are the pictures of our recent cleaning service where you can see how the dust looks and stays on the blades after the steam cleaning.

Why Your Dishwasher Isn’t Draining and What You Can Do

Why Your Dishwasher Isn’t Draining and What You Can Do

Dishwasher with water not draining after cycle
If after the dishwashing cycle you detect water left inside, you have got a classic dishwasher not draining problem.

To tell the truth, this is, perhaps one of the most common dishwasher problems. For example, when we get a request for Miele dishwasher repair in London, in half of the cases it is a problem we discuss here.
The good news is that most such issues you can fix even without any complicated dishwasher repair tips.

But let’s discuss this in detail.

Quick Symptoms & Safety Checks

Before contacting a repair company, whether it is for domestic dishwasher repair or commercial dishwasher repair, we recommend a quick assessment and safety checks.

Quick Symptoms: Standing water vs. slow drain

When you detect water in the dishwashing tub, evaluate its amount. It may give you a quick key to what’s happened to your appliance.

Typically, there can be two cases:
  • Water standing to an inch or more – pump failure or control board issues
  • Just a small puddle –clogged filter or drain hose

Safety Checks: Switch off power and water

If it is a clog, you can tackle the issue without any preparation. In all the other cases, you need to prepare your appliance for the necessary procedures.

For this, first, turn off the water supply valve to ensure no water input. Second, unplug the unit from the socket to de-energise it to make it fully safe and ready for further fixes.

Most Common Causes

Now, let’s dive deeper into the common dishwasher problems that cause the issue. For example, when we get a request for Hobart dishwasher repair with complaints about poor draining, it is typically one of the following three causes.

Clogged filter or sump

This is where the problem arises first.

The filter task is to prevent food debris from getting inside the system. Over time, the filter becomes clogged and stops letting water drain out of the machine.

If some very fine particles escape the filter, they get into the sump. For example, on one of our last SIEMENS dishwasher service call-outs, we detected a critical sludge at the bottom of the sump. Over time, the sump may accumulate a large amount of such particles. In turn, such a clog results in preventing water from flowing out.

Blocked/kinked drain hose or air gap

This is the second issue that leads to poor draining.

Typically, a clog in these components results from oils, fats, and fine powder-like particles that get into the system. For example, after cooling, oils and fats turn into sludge that envelop the inner side of the hose and get accumulated in the gap. So, the problem may occur even with a clean filter.
When the clog becomes critical, water will not find enough space to go through, and issues with draining arise.

Faulty drain pump or impeller

This is a serious problem. For example, a few of our Bosch dishwasher repair call-outs were about a malfunctioning drain pump or a jammed impeller and it took time to repair without replacing. 

To clarify, water gets out of the dishwasher not because of gravity but due to the efforts of the drain pump. Over time, it can fail and stop working, which leads to the dishwasher not draining.

To go further, the drain pump consists of the impeller, a fan-like part that physically moves the water. If a toothpick or glass pieces slip through the filter and get into the system, they may jam the impeller, which stops its running.

Step-by-Step DIY Checks

Here are some dishwasher repair tips to follow when your dishwasher is not draining.

Clean the filter & sump

It is the easiest task. Just follow the steps:
  1. Locate the filter, the cylindrical item with a flat mesh piece
  2. Twist the filter left and remove it
  3. Put the parts in water and clean with a soft brush to remove sludge
  4. Wipe out the sump and get rid of the sludge there
  5. Place the filter back in its location and twist right to reassemble

Inspect and flush the drain hose

This is a more complicated task. So, to do it yourself, you need some basic knowledge of dishwasher installation and de-installation. To clarify, the drain hose is located on the side or back of the dishwasher. Therefore, to deal with it, you need access to this side or back. In other words, you need to pull your appliance from under the counter. If you aren’t sure you can do this, turn to professionals.
The DIY steps are as follows:
  1. Unplug your dishwasher to de-energise it
  2. Access the appliance side or back
  3. Locate the drain hose
  4. Check it at its entire length for kinks
  5. Arrange a pallet and sufficient cleaning cloth to deal with residual water
  6. Disconnect the hose (at its both sides)
  7. Flush the hose to get rid of blockages
  8. Connect the hose back as it was
  9. Plug in the appliance

Run a rinse/drain cycle & check error codes

If you detect a significant amount of water, do a quick DIY check that may help you identify the issue.

Run a quick washing cycle or drain-only cycle if your model has one. Listen carefully to the coming sounds:
  • A humming sound – the impeller is jammed or the pump has failed
  • No sound at all – the pump isn't getting power or is completely dead

In any of these cases, we recommend turning to an engineer and describing the signs you detected. If your dishwasher flashes with an error code, remember the code and inform your engineer about it.

When to Call an Engineer

Unless you are a professional engineer fully familiar with the dishwasher’s engineering in general and your model one in particular, your only DIY options include troubleshooting minor clogging and checking for error codes. For all other cases, it is recommended to turn to a professional.
In short, the cases when to call an engineer, cover:
  • Deep and severe clogging
  • Professional drain hose flushing
  • Any pump failures
  • Control board failure

Burning smell, tripped breaker, repeated errors

If you are facing repeated errors even after cleaning the filter and flushing the hose, it means the issue is somewhere else, and you need a professional to detect and fix it.

Burning smells or a tripped breaker is one of the most dangerous issues for your safety:
  • A burning smell indicates a serious electrical fault
  • The tripped breaker indicates a short circuit in the pump or wiring

So, if you notice them, stop using the dishwasher and contact an engineer without delay.

Prevention & Maintenance Checklist

While there are many causes for a dishwasher not draining, you can prevent most of them. Here is a brief prevention and maintenance checklist:
  • Scrape plates before loading
  • Clean the filter every 30-40 cycles
  • Protect the machine control board from surge with a dedicated a surge protector 
  • Keep the control panel clean and dry
  • De-energise the unit to reset it and clear temporary glitches from the control board's memory
