Bosch Dishwasher Clicking Sound???
« on: November 22, 2014, 07:11:49 AM »

I have a Bosch dishwasher that doesn't respond to any of the controls other then the power button. When I power the unit off, a clicking sound comes from the control board. It clicks 10 times every time i turn it off.
I replaced the control panel and that did not fix it.
The only lights that come on are the auto wash the clean light no matter what I try.
I've tried getting it to give me a trouble code but it will not respond.
I don't want to keep throwing expensive parts at it hoping it will fix it.
I'm kinda lost on what to check for next so, any help would be greatly appreciated.
This is the model # SHX4AP05UC/02

Thanks in advance!!

From what you say, I'd check for something caught in the drain pump impeller.

I took the dishwasher out and checked the drain pump but I didn't find anything wrong with it.

Is there a way to check the main control unit?
I took it off and opened it up to check for any burned solder joint but I didn't find any.
Is there a repair manual for this model that I can download?

Something else to add to the problem. I noticed the control panel lights are staying on even with the door closed.
When it was working properly those lights always turned off.

Also, how does the door latch switch work on this model?
I took it apart but its not a traditional switch like I'm used to seeing so I'm not sure how to test it.

So I should be able to test that with my ohm meter right?
Switch removed should read as an open and switch in place should read closed right?

I should be able to hot wire that connector going the switch to make it work temporarily right?
