If your Asko dishwasher is overflowing, start with the most likely cause: a bad water inlet valve. When this valve sticks open or does not shut off fully, the dishwasher can overfill, leave standing water in the tub, or let water drip in even when the machine is off. Another less common cause is a main control board or control board that keeps sending power to the valve when it should not. If the leak seems like an overflow but water is actually splashing out near the door, check the lower wash arm assembly for cracks or splits. Also make sure you are using the right dishwasher detergent and the right amount, since too much soap can create oversudsing and make an Asko dishwasher overflowing problem look worse. Finally, inspect the float switch, since a stuck or failed switch may not stop the fill cycle when the water level gets too high.

01 - Asko Dishwasher Water Inlet Valve
The water inlet valve is an electrically-controlled valve that opens to allow water to enter the dishwasher. Depending on the model, the valve stays open either for a set length of time or until the dishwasher has enough water. However, if the water inlet valve doesn’t shut off after the dishwasher has enough water, the dishwasher will overflow. If water drips into the dishwasher when the door is open, or if water collects at the bottom of the dishwasher while it is not use, you may need to replace the water inlet valve.

A dishwasher's main control board provides power to nearly every electrical component in the dishwasher. If the control board continues to send power to the water inlet valve during the drain cycle, the dishwasher could overflow. While this is not that common of a problem, you can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test the water inlet valve for incoming power during the dishwasher's cycle.
If the lower wash arm has a crack or split on the side it can cause water to splash out the bottom of the door, giving the impression that the dishwasher is overflowing. Inspect the wash arm assembly for any damage and replace if necessary.
Make sure to use the proper dishwasher detergent. Use the proper amount of detergent for your water hardness; too much soap in soft water can cause oversudsing and leaking.
