Hello. My dishwasher pump and motor will intermittently not work (Sometimes yes, sometimes no). Sometimes the dishwashwer overflows with water in the tub because the pump won't kick on. Usually, however, what I find is that the dishwasher will go through a complete wash cycle and there will be standing water in the bottom of the dishwashwer. I'll attempt to run it through a "reset cycle" (where the lights flash), and sometimes the pump will work and sometimes it won't. Usually, if I wait until everything cools down, the pump will work. Also, I've found that there are no clogs (just tore everything apart), and when the pump and motor don't work, there's no sound (almost like a relay isn't kicking the motor/pump on). Any ideas?
ANSWER Hi Jay. Remove the lower kick panel. Remove the lower rack. Remove the float and clean the tub hole and the float stem and underside of the float. If the stem does not slide up and down effortlessly then it will not contact the float switch on and off. The float switch part # WD12X10151 interrupts the neutral feed to the water valve part # WD15X10003. If the water valve inlet screen is clogged it will not shut off and continue to fill the tub. Ohm the water valve for resistance and if each terminal to the valve metal body for shorts. Then clean the pump. Replace it if the armature does not turn with some resistance. If the impeller spins loose on the shaft, replace the pump part # WD26X10043. Make sure the drain hose is not clogged or the sink connection where the hose hooks up. Loop the drain hose and mount it as high up on the back wall under the sink. Then connect the rest of the hose taught to the sink connection. Make sure all wires are tight. It will be advantageous to find the supplied tech sheet inside the cabinet to aid you in the diagnosis. It allows you to put the unit in a diagnostic mode which brings up fault codes and tells you which circuit needs assistance. Thank You.
