My DW will not stop filling and draining. I changed control board, flow switch, and water fill assembly. Nothing helped. A few things I've noticed:
*The arm inside the dishwasher never turns- always stays in same position.
*The dishes never get wet (I guess due to arm not turning).
*When I open door during filling and draining I always have water in bottom of dishwasher. I have to hit the "drain" buttons to rid of it.
*The cycle time minutes never run down- they always stay at the initial cycle time.
*If I am doing the "test" mode correctly, DW is show a "4"- which I think idicates a fill problem.
I am lost, pls help! Just bought house and though DW was good. Do not want to pay $125 to have someone look at it.

Re: Bosch Dishwaher shy56a
Certainly sounds like the float is stuck in the over filled position or possible a bad float switch. Could also be a bad water
fill valve - if you can blow air through it when removed then you need to replace it.
You can follow this link to troubleshoot your washer, but note that its not exactly for your model - http://www.thermador.com/replacementparts/main/pdfs/SHU-complete-troubleshooting-guide.pdf

Here is what I found that makes my bosch dishwasher come on. It has the same problems as the OP. I pick the cycle I want press start. The DW will sound like it's trying to drain. I let it run that cycle which takes about 30 seconds. It then starts another cycle that sounds different from the first and when it stops I turn the DW off and then back on, it resets and then it starts the wash cycle. I've done this twice and it has worked both times. I do not know what is causing this but it's better then what I had to do to get it to reset.
Check the drain pump it is located in the front of you unit .Disconnect power or flip breaker .Remove the front kick plate then there is a metal plate above that is held on with 4 screws remove that and reach in and press lever on pump and turn counter clockwise it will come right out .Then check for items in the pump area could be glass. Hope it is helpfull
make sure that nothing is blocking the drain pump assembly located inside the
bottom of the unit, after this test the lid switch assembly, you jump it to
test it. If the lid switch is also fine then the control board should be
replaced. Hope this helps...please post back for further assistance.
If the water inlet
valve is fine and it fills with water then theissue seems to be with the float
switch assembly that is bad and should be replaced. Float assembly is found
inside the dishwasher's tub, on the bottom. The water that fills the dishwasher
lifts the float, and when it reaches a certain level, it acts as a trigger for
the float switch. The float triggers the float switch to shut off, thereby
shutting off the flow of water into the dishwasher. A defective switch may
interfere with dishwasher's filling and/or draining ability. Use voltmeter to
test the switch. Set the device to the ohms setting x 1. Take each probe and
touch them to one switch terminal each. This should produce a reading of either
zero or infinity. Continue to touch the probes to the terminals, and press down
on the switch's button. The reading should change to the opposite extreme. If
the switch fails either of these tests, you should replace it.Hope this helps...please post back for
From your description, I doubt that the problem is door latch is the cause.
The first thing that a modern dishwasher does before it begins to fill with water is run the drain pump. It appears that this DW is not progressing to the next cycle (inlet water) and because the pump runs even when the door is open, I agree that the controller card may have failed.
If possible, inspect all the wire connections (remove main power before you do this) ... if there is a loose connection, the controller could do odd things.
Good Luck! Please report back what you find, OK?
Bosch dishwashers have a seperate pump for washing and another for draining. Try making it fill more than once. There is usually a timed fill and the float stops it before it overfills It also might prevent it from washing without enouth water Try defeating the door switch and play with the float during fill. There may be a sensor that won't let it go into wash. Be prepared to get a little wet if it should start up suddenly. A slightly safer way is to fill it with the sprayer from the sink. and see if it will go into wash.
when facing the dw pull it out from under counter and on the left side there is a panel held on with 2 screws. take that off and under there are the float switches for the overflow. those switches is what causes the pump to run all the time but do nothing else.
