Possible Causes
Drain hose installed too low causing siphoning, Incorrect air break installation, Blocked air admittance, Faulty drain pump control on board
How to Fix / Troubleshooting
Safety first: Disconnect power and avoid contact with hot water.
- Check drain hose height: Ensure the hose rises to the recommended height behind the machine before connecting to the drain. Too low can cause continuous draining.
- Verify air break: If an external air break is used, confirm it is installed correctly and not blocked.
- Inspect drain pump operation: Listen for continuous running of the pump. If it never stops, even with correct hose routing, the control board or level sensing may be faulty.
- Correct installation: Adjust hose routing and secure it to prevent siphoning. If E18 persists, consult a technician to test the control board and level sensors.
