Possible Causes

How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Unplug the dishwasher and turn off water immediately.
- Inspect base for leaks: Remove the kick panel and check for water in the base tray. Dry thoroughly and identify any leaks as per leak faults.
- Check heater: Disconnect the heater and try running a short cold cycle. If the breaker no longer trips, the heater element is likely leaking to earth and must be replaced.
- Inspect wiring: Look for chafed or burnt wires, especially where the harness passes through metal panels or near moving parts.
- Professional testing: Insulation resistance testing is recommended and may require a qualified technician.
