Problem summary
Your Nordmende integrated dishwasher is causing the household electrics to trip. This is a safety fault and means current is leaking somewhere in the appliance's electrical path. It may trip every time you run the machine, or intermittently.
Likely causes
Based on historical repair data, the most common causes of tripping in models in the Nordmende range are:
- Heater element failure – The heating element can develop a fault that allows electricity to escape to earth, triggering the trip. This happens in approximately 8.6% of cases.
- Control board (PCB) fault – Damage or component failure on the printed circuit board can cause an earth fault. Also around 8.6% of reported cases.
- Door seal degradation – A damaged or worn door seal allows water ingress, which can create short circuits in electrical components. Seen in about 6.9% of cases.
Other possibilities include a faulty microswitch, loose internal wiring, or a compromised mains lead.
Why this needs an engineer
All of these faults involve either: - Mains voltage electrical work (heater, PCB, wiring) - Sealed system components (door seal interaction with electrics) - Parts that require safe disconnection and testing
Attempting to diagnose or repair these yourself risks electric shock, water damage, or further component failure. Additionally, working on a faulty appliance that is already tripping your home's circuit breaker is unsafe.
A qualified engineer will use an earth-leakage tester and voltage probe to locate the fault safely, identify the faulty component, and replace it to restore safe operation.
Safety steps to take now
- Stop using the dishwasher immediately. Do not run another cycle.
- Check your electrics. If the machine trips the main switch, isolate the circuit or unplug the appliance to prevent repeated trips.
- Do not force the trip switch back on if it keeps failing – this is a warning sign of a genuine fault.
When to call SMC Services
If your dishwasher has tripped the electrics once or repeatedly, book a repair as soon as possible. Continuing to use it risks damage to other appliances on the circuit and potential safety hazards. Our engineers carry common replacement parts for Nordmende models and can usually diagnose the exact fault on first visit.
If you're in Northern Ireland, SMC Services can usually book a repair within 2-3 working days.
