Asko dishwashers use an auxiliary drain motor, the drain hose connects to this drain motor behind the toe kick. Often on Asko dishwashers the drain motor will either fail or become clogged with foreign debris. To determine if the drain motor has failed or clogged, the toe kick panel must be removed. To remove the toe kick a T-20 bit will be needed, the screws on Asko dishwashers are a little different compared to an American dishwasher. When the toe kick is removed access to the dishwashers main components will be accessible. These include the wash motor, drain motor, thermostat and several other dishwasher components.
Obviously at this point power to the dishwasher has been shut off, the two wires that connect to the top of the drain motor will need to be removed, pulling out on each one sharply should do the trick. On the side of the drain motor there is a small tab once depressed it will allow the pump to twist past the locking tab releasing the drain motor.
If the drain motor is clogged with glass or food it will be apparent right away. Remove the foreign debris and test the dishwasher for proper function. If the unit fails to initiate a drain cycle the drain motor will need to be replaced. Before replacing the drain motor verify that the pump is getting proper voltage from the main control board. A volt meter will be necessary to check the proper voltage. You can purchase one from the link provided below
