My dish washer drain pump stopped working. I replaced with part # 6-917641. Once I connect the power, the drain pump started running. Initially I thought, there might be some water inside and it's attempting to drain. The drain pump sound is there always. When I start a cycle, I hear water gushing sound and motor starting sound. At the end of the cycle, there is no water inside. That means drain pump is working. However it's not stopping at the end of the cycle. I have to leave the door open or cut the power to turn off pump. So far I ran two( 2) complete cycles. Once without any dishes and next time with dishes. The dishes are not cleaned.What could be the problem? Are there any diagnostics, I can perform? Thanks in advance.
ANSWER SK, Yes there are diagnostic tests you can perform. You will need to remove the lower kickplate and access panel from the front of the dishwasher. you should find the tech data information sheet attached to the backside of the kickplate, in a plastic bag, if it hasn't been lost or misplaced. This dishwasher circuitry isn't too complicated, as long as there is power to the dishwasher and the door is latched, there is 120 VAC supplied to all the components in the dishwasher. The control board controls the neutral leg of the circuit in order for the motors etc. to operate. You will need to check the wiring harness, especially the gray wire from the control board to the drain pump for shorts or pinches to the frame or cabinet. Especially at the bottom of the door/ and in the door liner. If all's OK, the control board would be the next and best option.
