AS
Anti-Stain Sensor Fault
If your Electrolux Dryer is displaying the error code AS, the control board has detected a fault identified as "Anti-Stain Sensor Fault". Understanding the root cause helps you avoid an unnecessary service call.
Owner's Summary
Electrolux's AS code relates to the moisture sensing system used to automatically end cycles. Residue from fabric softener on the sensor bars is the most common cause, and cleaning them is a free fix.
Symptoms
Electrolux dryer ending cycles inconsistently, AS error code
Common Causes
- Moisture sensor bars coated with residue
- Faulty moisture sensor module
- Wiring fault to sensor
- Control board calibration issue
How to Fix
- 1 Clean moisture sensor bars inside the drum with rubbing alcohol
- 2 Avoid fabric softener sheets touching the sensor area
- 3 Inspect wiring harness to sensor
- 4 Replace sensor module if issue persists
Tools You'll Need
These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.
Technical Explanation
The control board uses moisture sensor bar conductivity to determine when garments reach target dryness. AS is generated when sensor readings are inconsistent with expected patterns, often due to residue interfering with electrical contact.
Is It Safe to Keep Using?
No safety risk. Fix within a few weeks for optimal drying performance.
Technician's Pro Tip
Electrolux and Frigidaire share moisture sensor designs across many models — cleaning procedures and replacement parts often cross-reference between the two brands.
