Having problems with your Bosch 24 in. SHU43 Built-in Dishwasher ?

Bosch SHU4312 won't finish cycle, won't drain.

\015 We have a Bosch SHU4312 that is over 10 years old. It has worked fine until last night it began the scrub cycle, filled with water, dumped soap, and ran for over 3 hours, washing with water circulating inside, without pumping any water out. It made a "humm-whish" noise over and over. Soapy water inside was steamy hot, and there was no overfill. None of the filters were plugged.\015

Answers :

The control board on these units is prone to a cold solder joint cracking. I have read that Bosch recommends replacement and will supply the board, not covering labor. I repaired mine prior and have done one for a friend as well. Has lasted several years and counting
The symptom is constant cycling without ticking down the last few minutes
I solved this by replacing the controller module. It had a PC board failure that was obvious upon inspection.

First we had drain issue with Bosch Integra® 500 SHX55M05UC Built-in Dishwasher ECO cycle. It stopped after a while. I thought it may be because last cycle might not be finished well. When we ran again ECO cycle with no drain issues but cycle did not finished as it used to be. I am sure because cycle countdown were not zero and because infra red light was off which is sing of complete cycle.

Bosch dishwasher My Bosch dishwasher finished a wash cycle and was showing the "END" light on, however, the motor was still running as though it was stuck on the drain cycle (there is a gurgling sound from where the eater drains off beneath the filter. Subsequently turning the washer on just repeats the apparent drain cycle with a constant gurgling sound (it does not kick into wash mode). The number on the manual is & 258 (7705).

My Bosch Dishwasher does not drain all the water out of the dish washer after the finishing cycle...I usually start the washer and then push the drain cycle and it starts to pump for about 10 seconds and stops and starts and pumps again for 10 seconds and stops and then pumps for about 25 seconds and stops....doing this manual drain twice empties the dishwasher of the excess water....what may the problem be?

Shu9925uc/14 bosch dishwasher leaves standing water in the bottom of the pump. The pump seems to be bad because it wont drain out the back hose. I have run the diswasher full cycle and put the drain hose into the sink to test. It wont drain at all now and I dont hear the pump. Perhaps unrelated: Pump seemed to stop working after the back hose disconnected itself from the back of the unit spilling water all over the floor. When I reconnected the unit to the wall the pump now seems to be disfunct

EDW5500DSS wont completely drain water Okay so now that my dishwasher runs, when it finishes a cycle it has a nice puddle of water at the bottom that never drains completely out.

I really want to solve this problem soon so I can order the new door seal and needed part together. Checked the line out and of course i
