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

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.
Check for any water leaks around the dishwasher, especially near the door seal and internal components. Dry any wet areas and replace seals or components as necessary.
