If I come across short, please excuse me. I am just so pissed with my dishwasher.

Here is my story, I installed a Bosch SHU43C02UC in late 12/2006.
About a month ago it stopped draining properly, but still draining some water. I was thinking a clog.
To check for a clog I removed the entire drain line from the rear of the dishwasher to the disposal and sucked it with my shop vac. No clogs. I called in my "Bosch Authorized Repairman." He looks at it and tells me it is my control module. I bought a new control module directly from Bosch and installed it today. Now, it runs the cycle completely, but it does not drain at all. It does run better with new control module. With the old control module, during the drain cycle the pump would turn off and on constantly, as if searching for the right gear. Can anyone help me with my problem? Thank you.

Phil

Most of the newer ones (including yours I think) will cycle the pump on and off several times at the beginning of a drain cycle, but they have also changed up impeller profiles several times, I have replaced many pumps in those because the impellers slip on the shaft

Did this "Bosch Authorized Repairman", know anything about the repair recall on the control board?

Your model is one that is on the repair recall list depending on your date code, (if FD8205 thru FD8507 the control board should have been replaced for free).

http://microsites.bo...all/dishwasher/

Bosch home appliances have announced a voluntary recall to repair certain Bosch dishwashers manufactured from May 1999 - July 2005.


You installed yours 12/2006, it could have been built before July 2005 and been in a warehouse somewhere.

Go to the above website and put your model and serial number in and if it comes up that it is under the recall you should talk to this "Bosch Authorized Repairman" about getting your money back.

I know what you mean, it has always cycled the pump at the beginning, when you first start the dishwasher. I am talking at the very end of any wash cycle, when it empties the dirty water or rinse water.

Thanks Willie, but not sure it matters since this is my 3rd control board.

I removed the drain pump. I did not find any blockage or gunk. The impeller does turn, but not easily. It spins as if it is spring loaded.

I posted a video of me trying to spin the impeller. I hope you can see what I mean. Link to video

Here is a still picture of the impeller. If that helps diagnose my problem. Posted Image

Thanks.

That's the magnetic resistance in the motor field. The real test is to run the pump with it out of the dishwasher and see if it acts like this one:

If so, come git you a new drain pump ==> http://www.repaircli...nd-Motor/935403

Thanks. Check out my video of my motor running outside the dishwasher.

My motor is making a noise similar to the KitchenAid motor, but not as pronounced. Listen carefully and let me know if the motor is shot. thanks. Bad Motor? One other thing, I have the meter connected, which proves there is 123.9VAC at the motor. At least I know I got the correct voltage.


I apologize for the jumpiness, I did not have enough arms to make a better video.

Thanks for the help.

Phil

Here is a better quality video of the motor running. For some reason the motor's noise is more pronounced than it sounds live. I don't know why. Better quality video

Video doesn't work for me - put pump back in dishwasher, pour some water into dishwashe and power pump with a cheater cord (repeat several time if necessary) Does it fail to pump out all the water ? - replace pump
