Washer-dryer combo displays E18; unit may stop mid-cycle with no obvious mechanical issue.

Safety first: Unplug the appliance before handling wiring or boards.

• 1. Perform a power reset: Unplug for 5–10 minutes, then plug back in and attempt a short cycle.
• 2. Inspect internal harnesses: Remove the top and rear panels. Follow the wiring from sensors (NTC, pressure sensor, door lock, etc.) to the main board. Reseat each connector.
• 3. Look for corrosion or moisture: Pay attention to connectors near the tub or vent where condensation can form. Clean and dry as needed.
• 4. Check for pinched or broken wires: Repair or replace damaged sections of the harness.
• 5. If E18 persists after reseating and inspection: One of the sensors or the control board may be defective. Replace the most suspect sensor first, then the board if necessary.
