E11 Moderate Moderate DIY
Bosch Dryer E11 — Moisture Sensor Fault
Bosch Dryer · Error code E11
What E11 Means
The two metal sensor strips inside the drum that detect garment moisture are not reading correctly — either coated with residue or wiring is open.
Symptoms
- Auto-dry cycles stop too early or run too long
- Clothes come out damp or over-dried
- E11 displayed at end of cycle
- Sensor-dry mode unavailable
Common Causes
1
Dryer sheet residue on sensor strips
Fabric softener residue insulates the strips and prevents accurate readings.
2
Worn-through sensor strips
After years of garment contact, the conductive strips erode.
3
Loose or broken wiring to sensor
Connector behind the drum has worked loose.
4
Failed sensor input on control board
Rare — board input damaged.
How to Fix It
- Open the dryer door and locate the two metal sensor strips on the front bulkhead (just below the door opening) or inside the drum.
- Wipe the strips thoroughly with a cloth dampened with rubbing alcohol or vinegar to remove softener residue.
- Inspect strips for visible erosion — replace the sensor assembly if worn through.
- If cleaning doesn't restore function, unplug the dryer and remove the front panel to access the sensor harness.
- Reseat the connector at the sensor and verify wiring continuity.
- Test sensor by shorting the two strips with a wet finger — control should detect moisture.
- Replace sensor assembly if testing fails after cleaning.
- Reassemble and run an auto-dry cycle to verify.
