ASKO Dryer Error Code F5

F5 on an Asko dryer means the maximum allowed programme time of 3 hours has been exceeded and the machine has stopped itself. The dryer was unable to complete its drying cycle within the time limit, which points to a condition that is slowing down drying efficiency. Common triggers include overly wet laundry, blocked air passages, a faulty thermistor, or a control unit that needs a full reset.

The dryer stops automatically when F5 is triggered, so it is not actively running while the error is displayed. You should not attempt to repeatedly restart the machine without investigating the underlying cause, as persistent extended cycle times can indicate a component fault that may worsen over time. Resolve the issue before returning the dryer to normal use.

If the fix is something you can do yourself, such as clearing a blocked air vent or adjusting the spin speed on your washer, there is no parts cost involved. Thermistor replacement is generally an affordable repair, typically in the range of $20 to $80 for the part plus any labor costs. Control unit replacement is more involved and can range from $150 to $400 or more depending on parts availability and the technician's rates.

In many cases, yes. Start by switching the dryer off and leaving it unpowered for at least 30 minutes to allow the control unit to fully reset. Then check that the external air passages are unobstructed, and make sure future loads have been spun at 800 rpm or higher before drying. If the error returns after these steps, a defective thermistor or control unit is likely involved and professional diagnosis is recommended.

A full power-off reset, with the machine switched off for at least 30 minutes, may clear the F5 error if the root cause was a temporary condition such as an exceptionally wet load or a control unit that did not complete its previous reset. However, if the underlying problem is a blocked air path, defective thermistor, or faulty control unit, the error will return after the next cycle reaches the 3-hour limit.
