The routine essentials

Daily maintenance

There are a few maintenance routines, simple hygienic activities, to undertake after every use of your coffee machine:

• Rinse the portafilter
  
• Purge the steam wand
  
• Clean the drip tray
  

​Respectively, these activities prevent oil build-ups, blockages with dried milk, and water pooling under your machine.

Weekly maintenance

Once a week, do not forget to arrange overall cleaning for your appliance. The routine should include the following activities:

• Backflush and descale the machine
• Clean the unit

​By backflushing with a special detergent, you get rid of the coffee oil residue, which can ruin your espresso taste and clog the solenoid valve. By descaling with a recommended descaling solution, you get rid of mineral scale, which accumulates on the boiler and water pathways and can restrict water flow or even cause temperature instability. When cleaning the machine, wipe down the exterior, group head area, and steam wand to ensure no coffee grounds or milk residue are left behind. Then, wash removable parts in soapy water.

Advanced tips for preventative maintenance

Use the right water

One of the common causes for performance decline in espresso machines is hard water. For example, in areas with hard water limescale builds up twice as fast as in soft water areas. So, use water filters to remove extra calcium carbonate from water and soften it.

Drain and refill the steam boiler monthly

When you steam milk, you pull steam from the boiler but leave the water minerals behind. Over time, these minerals concentrate. So, regularly drain the water from the steam boiler and refill it with fresh water.

Proactively replace consumable parts

Don't wait for consumable parts to fail but replace them in time. Depending on the usage intensity, replace the group head gasket, shower screen, and portafilter baskets every 6-12 months.

To conclude, it is also recommended to arrange professional servicing for your coffee machine. An experienced coffee machine engineer will not just do a professional boiler descaling but can catch problems that are invisible to you – for example, faulty fittings or failing solenoid coils. All this helps you keep your coffee machine running for years and prevent costly breakdowns.
