ASKO Washer Error Code Overfilling

The overfilling error on an Asko washer (W640, W650, W660) means the drum has filled with more water than the programmed level allows. The fault is triggered by the level sensing system detecting water above the intended threshold. This is typically caused by a failing inlet valve that will not close, or a pressure switch that is not accurately reading the water level. The machine halts operation to prevent overflow and potential water damage.

No, you should not continue running the washer when this error is active. An overfilling condition means water may already be at a dangerous level inside the drum, and continued operation risks water overflowing onto the floor and causing damage to flooring, cabinetry, or subfloor structures. Turn off the water supply to the machine and disconnect power until the fault has been diagnosed and repaired.

Repair costs vary depending on which component has failed. A replacement inlet valve or pressure switch typically costs between $25 and $80 for the part alone. If professional labor is required, total repair costs including parts and service time generally range from $100 to $250, depending on your location and the technician's rates. Diagnosing and clearing a blocked pressure hose with no parts needed would fall at the lower end of any service call cost.

Some causes of this error are accessible to a knowledgeable DIYer. Checking the pressure sensing hose for kinks, blockages, or disconnection requires no special tools and can be done after disconnecting power and water to the machine. Testing or replacing the pressure switch and inlet valve involves working with electrical and plumbing components, which many experienced DIYers can handle, though calling a qualified technician is recommended if you are unsure.

Resetting the machine by cutting power for a few minutes may temporarily clear the displayed error, but it will not fix the underlying problem. If the inlet valve or level sensing system is faulty, the condition will return during the next wash cycle. A proper repair of the defective component is required to permanently resolve the fault.
