Possible Causes
Failed main relay supplying power to loads, Broken common neutral connection, Faulty main control PCB logic output, Loose multi‑pin connector from PCB to loads
How to Fix / Troubleshooting
Safety first: Unplug before opening. Mains voltage is present on load wiring.
- Check safety interlocks: Ensure the basket is fully inserted and any lid or door is properly closed; safety switches can prevent operation.
- Inspect load connector: Open the housing and locate the multi‑pin connector that feeds the fan and heater. Ensure it is fully seated.
- Check main relay: Identify the main power relay on the PCB. Listen for a click when starting a cycle. If no click, the relay coil or drive circuit may be faulty.
- Test continuity: With power disconnected, test continuity from the relay output to the fan and heater inputs. Repair any open connections.
Warning: If you are not experienced with mains wiring, do not attempt live testing. Seek professional help.
