Zanussi Dishwasher: tripping breaker
What is this symptom?
If your Zanussi dishwasher is tripping the circuit breaker when powered on or during operation, it indicates an electrical overload or fault. Common causes include internal shorts, overloaded circuits, or faulty components. Addressing this issue promptly is crucial to prevent further damage and ensure safe operation.
Important Tips for Zanussi Models
- Official Zanussi guidance notes that dishwasher short-circuits and trips RCD breakers due to leakage to ground or internal shorts, and recommends using a proper circuit and contacting service if unresolved
Possible Causes
Internal electrical short or ground fault
How to Identify: Breaker trips immediately or soon after starting; possible water leakage inside base or puddling under dishwasher; visible damaged wires if accessible
Part: Wiring harness, insulation, internal components
Overloaded circuit
How to Identify: Breaker trips only when dishwasher runs alongside other appliances; breaker stays on if dishwasher runs alone
Part: Electrical circuit to dishwasher
Faulty motor or pump drawing excessive current
How to Identify: Breaker trips when motor starts or during wash cycle; humming or abnormal noise from motor prior to trip
Part: Wash motor/pump assembly
Water leakage causing electrical fault
How to Identify: Signs of water leaks around dishwasher; breaker trips after water ingress observed; moisture inside base
Part: Door seal, internal seals, wiring junctions
DIY Solutions
Test circuit load and isolate dishwasher circuit
- Ensure dishwasher shares no circuit with other high-draw appliances
- Turn off/reset breaker and run dishwasher alone
- Observe if breaker trips without other loads
Visual inspection for water leaks and drying base
- Turn off power at breaker
- Pull out dishwasher and check floor pan and interior for water
- Dry any moisture and replace damaged door seals if visible

-
Inspect and replace the heating element if it's faulty. Disconnect the dishwasher, remove the heating element, and test it with a multimeter for continuity. If it shows no continuity, replace it with a new one.
-
Examine the power cord and plug for any visible damage. If damaged, replace the power cord. Ensure the connections are secure and the plug is not overheating.
