Question about Bosch 24 in. SHU5305UC Built-in Dishwasher
I ran the diagnostic program and after a few minutes i get a 4 code. In addition the display also displays two periods one in front of the 4 and one after the 4. I believe that the 4 code is indicating a water level switch problem. The water switch is part of an assembly that has a blue plastic part that is pushed by a diaphragm . I have the machine out so i can see the switch assembly and the switch never gets closed. I can't see how the water flow can close the switch?

SOURCE: Long cycle times
Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows: On some units, the pause is timed and the unit continues after the allotted time. On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too. About the led: If your dishwasher has a digital readout and you see an error code, it may indicate a problem with the unit. If this happens, look up the error code in your owner's manual to find out what the problem is.

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 Good luck!

Sounds like you already know how to fix it. The inlet valve is only held closed by water pressure...if you have low water pressure it could be causing this. Its more likely just a bad fill valve though. The water inlet valve is accessed by removinf the lower kickplate and the sheild behind that. Then all you have to do is remove the water line from the valve, remove the 2 screws holding it and pull it out far enough to disconnect the 2(possibly 3) wires and the fill hose. Make sure to mark where your wires go, if you hook it up wrong it could continue to fill and overflow. Hope this helps!

you have to replaced the main control resoldering wont fix it because the relay itself has gone bad replacing the board will solve the problem

if the door doesn't shut, the push buttons should not work. that way you are not running your d/w with the door open. check the door latch, as it seems to be malfunctioning. if the d/w still does not work, replace the door latch.
