How to Fix / Troubleshooting
Safety: Unplug the appliance before accessing electronic modules.
- Power cycle: Disconnect power for 10 minutes, then reconnect and try a short cycle to see if the error clears.
- Check connectors: Access the main PCB and motor inverter module (often mounted near the motor). Reseat all multi-pin connectors and inspect for corrosion or burning.
- Inspect harness: Look for damage to the communication cable between the boards. Replace if any conductors are broken or insulation is worn.
- Module testing: Without specialist tools, inverter and PCB testing is limited. If E18 recurs after reseating connectors, one of the boards is likely faulty and should be replaced following Belling part guidance.
- Professional service: Due to high voltages and complexity, communication faults are best handled by a qualified technician.
