Possible Causes
Loose sensor harness connector, Faulty internal sensor module (e.g. combined NTC/humidity board), Damaged wiring loom, Main PCB communication failure
How to Fix / Troubleshooting
Safety first: Unplug the dryer before removing any panels or touching internal wiring.
- Identify sensor modules: Refer to the service diagram (if available) to locate internal sensor boards (e.g. humidity/NTC combo boards on the duct or near the drum).
- Check connectors: Reseat all multi-pin connectors between sensors and the main PCB. Ensure locking tabs click into place.
- Inspect wiring loom: Follow the harness for signs of chafing, pinching, or broken insulation, especially where it passes through metal openings. Repair or replace damaged sections.
- Visual check of sensor boards: Look for corrosion, moisture damage, or burnt components on small sensor PCBs. Replace any suspect board.
- Test run: Reassemble and run a test cycle. If E11 persists, the main PCB may not be reading the sensors correctly and likely requires professional replacement.
