How to Fix / Troubleshooting
Safety: Disconnect from mains before inspection.
- Perform visual inspection: Open the main access panels and look for burnt components, loose connectors, or pinched wires.
- Reseat all connectors: One by one, unplug and firmly reconnect all harnesses to the main control board, sensors, fans, and compressor relay.
- Check for recent changes: If parts were recently replaced, verify wiring against the Indesit wiring diagram to ensure no connectors are swapped.
- Run diagnostic mode: If available, enter service diagnostics to identify which subtest fails. Replace the indicated component (sensor, fan, valve, etc.).
- Replace main control board: If no specific component fault is found and E18 persists, the main board may be defective.
