Possible Causes
Burnt heater relay on PCB, Damaged control module tracks, Shorted heater drawing excessive current, Wiring short in heater circuit
How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains before opening the control panel or base.
- Confirm heating issue: Run a hot program and check if dishes come out cold and wet. If so, heating control is likely affected.
- Visual inspection: Remove the outer door panel to access the control module. Inspect the PCB for burnt spots around the heater relay and connectors.
- Check wiring: Follow the heater wires from the base to the control board, ensuring there are no melted connectors or damaged insulation.
- Component replacement: If the relay or PCB is visibly damaged, the safest repair is to replace the entire control module with the correct Amica spare part.
- Professional service recommended: Because this involves live mains switching, a qualified technician should perform board-level repairs.
