MODEL#DFUD042PSS STAYING ON DRAINING CYCLE - Viking DFUD042 Built-in Dishwasher

i no this is not your model but it might give you some ideas... interior lights staying on Everything Electrical and Electronic

THERE IS A TURN SIGNAL RELAY , CHANGE IT!!

Hi.

If the machine is filling up, then cycling and draining, the problem is usually the belt. The belt is reached disassembling the appliance . If the belt is OK the problem is usually the motor or the motor control unit, which is a sealed electronic module connected to motor and to control board and located inside the washer. If the motor has volts and does not turn, then the motor must be replaced. In some less common case the control module itself may be responsible. Motor assembly and belt are located at the back of the drum and get accessed disassembling top and back of the washing machine.

If the machine does not go through the cycle, but it starts draining from start, then the problem is overfill detected. In that case check the drain system, the drain hose, the inlet valve and the pressure switch.

Hello,
I don't believe that a service manual exist i have included a image of the parts breakdown for the pump asm. and while taking look at it i believe the the drain solonoid is hanging up,or the drain flapper in the pump asm is hanging open The solonoid is shown is that image as item #5 it connects to the drain flapper shaft item #13 and the actual flapper is number is item #34 and has a sping thats suppose to close it item #35
one of those is staying open not allowing the water to stay in tub on wash cycle

Man o man, just moved my same model Magnavox and have the same problem. Staying in demo mode...

Water staying in bottom is not a problem unless the dishwasher base is full of it and covers the wash arm.

This means the drain cycle is not working or dishwasher is shutting off before drain cycle.

Try to clean the filters at the base and check drain in kitchen sink side is clear.

Need the model number in case you want more specific instructions.

bad check valve!!! :)

I believe you may be over sudsing, Try a few cycles with vinegar and no soap. Do not use dishwashing soap at any time ever. See if the vinegar trick helps...helijm
