What F5 means
F5 on the ASKO T731, an older dryer with an LED display, refers to the moisture sensor, the part that tells the dryer when clothes are dry. The owner's manual notes that running an empty or already dry load can trigger it, since the sensor sees no moisture to measure. The dryer ends the cycle and displays F5. We repair this older dryer.
Common causes of F5
- An empty or very dry load that gives the sensor nothing to read
- Residue on the sensor bars inside the drum
- Wiring, or the control board that interprets the sensor signal
1. Open the door, as the owner's manual suggests, to clear the message. 2. Make sure the load is damp rather than empty or already dry. 3. Restart the program with a normal load. 4. If F5 stays, hold off on further cycles and call us.
- Whether F5 appears only with dry loads or with damp laundry too
- Whether the sensor bars are damaged or coated
- Whether the wiring and control read a good sensor correctly
Other Dryer codes
Can a dry load cause F5?
Yes. The moisture sensor needs damp laundry to read. With an empty or already dry load it has nothing to measure, and the dryer can show F5.
How do I clear F5?
Open the door, as the owner's manual directs, and then start a normal load. If F5 still shows with damp clothes in the drum, the sensor circuit needs checking.
