How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker. Unplug the dishwasher and leave it disconnected until inspected.
- Inspect for leaks: Remove side and bottom panels and look for signs of water around the heater, pumps, and wiring.
- Dry thoroughly: If moisture is present, dry the area and identify the source of the leak for repair.
- Check wiring: Look for rubbed or pinched cables where the dishwasher slides into the cabinet.
- Professional testing: Insulation resistance tests with a megohmmeter are recommended to locate the leaking component (heater, motor, or filter).
- Replace faulty component: Once identified, replace the leaking heater, motor, or mains filter with CDA-compatible parts.
