What the F1 error code actually means

Your Asko washer detected too much water inside the machine, either in the drum or pooling at the bottom of the cabinet. This is usually caused by a water valve that is not closing properly, which lets water keep flowing in when it should stop. Turn off the machine at the main switch right away to stop the water flow and reset the error.

Questions people ask about F1

What does F1 mean on a Asko washer?
The F1 code on an Asko washer indicates an overflow condition. The water level sensor has detected that water has risen above the acceptable limit inside the drum, or on models with a float switch, water has been detected pooling at the base of the machine cabinet. This is commonly caused by an inlet valve that has jammed open and cannot stop the flow of water. The machine stops operation and displays F1 to protect against further water damage.
Is it safe to keep using my Asko washer when F1 is displayed?
You should not continue using the washer until the cause of the F1 error has been identified and corrected. An overflow condition means water may be entering areas of the machine not designed to handle it, or leaking into the cabinet base. Continued use risks water damage to your floor, surrounding cabinetry, and internal electrical components of the machine.
How much does it cost to repair an Asko washer showing an F1 error?
Repair costs vary depending on the root cause. Clearing a blocked drain hose or repositioning a kinked hose involves little to no parts cost, only labor if a technician is called. Replacing a faulty inlet valve typically runs in the range of $80 to $200 including parts and labor. A water level sensor or pressure sensor replacement can range from $100 to $250 depending on parts availability and service rates in your area.
Will turning the machine off and on clear the F1 error?
Turning off the main switch is the first recommended reset step and may clear the error message temporarily. However, if the underlying cause, such as a faulty inlet valve or a leak, has not been corrected, the F1 code will return once the machine is run again. A reset should only be used as the starting point for diagnosis, not as a final fix.
How do I fix the F1 error on my Asko washer?
Start by turning off the main switch and the water supply to the machine. Check the base of the cabinet for any standing water and inspect internal hoses and the door seal for leaks. Next, examine the inlet valve to see if it is allowing water to enter when the machine is off. If the valve, water level sensor, or drain system are found to be faulty, those components will need to be repaired or replaced.
