Randy for Model Number KUDP01iLBS0 Drain pump was working on initial startup. After it ran through the cycle,it wouldn't drain the water. Could the hot water be causing the pump blades to expand to the point it won't pump? It was pumping the water when I first started the dishwasher. You could see it draining into the disposal. After running the cycle, it wouldn't drain.
Answer Hello Randy. You will need to test and see if your getting power to the pump during the drain cycle. You may have a bad board WP8564543 if it is not sending power to the pump during the cycle. The hot water shouldn't affect the pump operations. Hope this helps. Read More... Answered by AppliancePartsPros.com | Monday, March 28, 2011
