Hi,

My shu43c02uc/40 bosch dishwasher does not drain water. The pump works well when I start it from the overflow mecanism. I mean, the pump evacuates water nicely. The dishwasher does not perform the draining activity for all the programs. The main control board is new. Is there any idea?

Thanks.

Does the dishwasher run a continuous cycle and not drain?  Is the new control advancing the cycle or stalling?  Could be a heating issue.  If the heater or NTC is shorted then the dishwasher may advance to the end of the cycle and just stall.  Why was the control module replaced?  Try running the Rinse Only cycle and see if it drains at the end.

Thanks Kohai,

 

I'll answer your questions.

 Yes. 
 
- Is the new control advancing the cycle or stalling?
 The unit control advancing the cycle and finishes without starting the draining pump.
 
- Could be a heating issue.  If the heater or NTC is shorted then the dishwasher may advance to the end of the cycle and just stall. 
 
 The heater works.
 
 
- Why was the control module replaced? 
 
The unit control was ploged to 220w and scrapped.
 
-Try running the Rinse Only cycle and see if it drains at the end.
 
I tried the Rince Only cycle and it does not drain.

If the drain pump works when the float is lifted then that eliminates the drain pump. Where did you get the control and did you wire it properly?
