Commercial dishwashers are the backbone of any busy restaurant, café, or hospitality establishment. When these machines malfunction, it can disrupt operations and lead to delays. If you're looking for dishwasher repair in London, understanding the common issues and their causes can save you time and money. 1. Blocked Drainage SystemOne of the most frequent problems in commercial dishwashers is a clogged drain. Food particles, grease, and debris can accumulate, leading to slow drainage or water pooling at the bottom. Over time, this can cause significant damage to the drainage system and even lead to water leaks. Immediate Action: Check and clean the dishwasher filters daily. Remove any visible debris from the drain and ensure the drainage pipes are free of blockages. Using a dishwasher-safe drain cleaner occasionally can also help prevent clogs. 2. Faulty Heating ElementsA commercial dishwasher's efficiency relies heavily on its ability to maintain the right water temperature for cleaning and sanitising. If dishes are coming out dirty, cloudy, or not properly sanitised, the heating element may be failing. Ignoring this can lead to poor hygiene and possible health code violations. Immediate Action: Regularly monitor the water temperature during cycles. If it's not reaching the required level, stop using the dishwasher and contact a professional engineer to replace the heating element. 3. Water Supply IssuesLow water pressure or interruptions in supply can significantly affect a dishwasher’s performance. Hard water can also lead to mineral build-up in spray arms and valves, reducing water flow and cleaning efficiency. Immediate Action: Check the water pressure and ensure the supply valve is fully open. Clean the spray arms and descale the system regularly to prevent mineral build-up. 4. Broken Door SealsLeaks around the dishwasher door are often caused by damaged or worn-out seals. Over time, this can lead to water damage on floors and create safety hazards in a busy kitchen. Immediate Action: Inspect the door seals weekly for cracks or wear. If you notice any damage, replace the seals immediately to avoid further leakage. 5. Electrical FailuresDishwashers rely on a network of electrical components to function effectively. Wiring issues or control panel malfunctions can cause erratic behaviour, unexpected shutdowns, or even complete appliance failure. Immediate Action: Turn off the power to the dishwasher and inspect the control panel for obvious signs of damage or loose wiring. For complex issues, always consult a professional engineer to avoid safety risks.
