Water and draining ok, washing not.

Wash pump went out. Drain pump still works.
Not enough water. Improper water fill.

Hello, How long has your dishwasher been do this? Have you washed dish's in it? Also, these German made dishwasher run on less than 2 1/2 gallons of water. These German manufactured dishwasher machines run really quite. Because of the German water conservancies laws. They limit the amount of water dishwasher and washing machine can use. Also, there is no storage hot water system in there homes, it on demand hot water. You can't hear the motor running and about the only thing one can hear is maybe the water washing the dishes.


Now, the water at the bottom of the dishwasher, if the drain isn't connected up under is the sink drain and trap area or the garbage disposable in the sink. but some place lower on the drain pipe. You will not have a spiffing effect on the the bottom of the dishwasher, it the same with washing machines. One the discharge pump starts sucking air, it will not drain the dishwasher. The siffen effect works if the water is below the outlet for the drain. Example: Home owner have the new washing running and continue fill with water. Why, because the drain pipe end is below the the bottom of the washing machine tub. It fill up with water and siffen action continues emptying the tube will it still filling. One heck of a water bill.

sounds like wash motor is not going . it will fill and control thinks motor is working . then it will drain wash water / ( drain pump is a different motor ) and then refill and so on .. never washes but fills and drains and heats. ( look for leakage under the motor i'm sure you will find some ..

If you are saying that in the wash cycle it fills and then stops it could be that your water temp is too low. Some models will stop to heat the water in the main wash before going into the agitate mode.

Checked water temperature at water heater. It was at 110 degrees. Turned water heater up to 125 degrees. Dishwasher works perfectly now.

Drain valve not opening or pump impeller loose on shaft - is it washing ok?

My guess would be drain valve not opening. It is a 110v solenoid and they get stuck or burn up. New solenoid costs ~$20.00

either
leaking valve - to check, turn water off and see if it still happens
or
if appliance is plumbed in to a spigot on the sink trap, then when you empty sink, some of the water finds its way into the dishwasher via the drain hose. to cure, take the drain hose as high as possible under the sink in a swan neck

More likely: the solenoid which directs the water to either the drain or the spray arm is clogged/jammed. Located underneath near the drain line.

impellor buggered. Needs replacing
