How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Unplug the dishwasher and leave it disconnected until the fault is found.

- Dry out appliance: If there has been a leak, allow the machine to dry completely before retesting.
- Professional testing: Earth leakage and insulation resistance tests require proper equipment. Contact a qualified technician to test the heater, pumps, and wiring.
