Only getting "humming" sound from dishwasher. Although water had filled the dishwasher tub, pump/motor would not operate. After some research, figured the motor had siezed and I had to replace the pump/motor assembly as mentioned on this site. The kit came in a couple days and I reserved a Sunday afternoon for the repair which I had never done before. Hardest part of repair was unhooking and removing dishwasher from under counter and then getting it back in proper place. I would suggest providing some instruction within the repair instructions showing how the dishwasher is installed or how to remove it as I had never installed one so I was not quite sure what screws etc I needed to remove on the dishwasher itself to start to remove it? I was able to find the original installation instruction for the dishwasher and found that all you had to do was remove two screws from the inside top of the dishwasher which were securing it to the bottom side of the kitchen counter and then the whole thing just slides out. Once removed, turned dishwasher over to access bottom where pump/motor is located. After determining which diagram to use with the instructions, proceeded to replace the motor/pump assembly. It came out easily after wrestling with some corroded bolts/nuts and the existing pump inlet and outlet hose clamps. Mine were old and worthless and no new ones (3-4") are supplied with the kit. Had to run to hardware store to get new hose clamps for the inlet/outlet of the pump before intalling new one. Suggest new hose clamps be provided with the kit. Only thing that was not too clear in instructions was when reconnecting power wiring harness to motor. By looking closely at the instruction diagram I was able to locate what looked to be the right power extension harness from the bag of parts and attach it to the existing power wire harness and the new motor. Suggest also that you somehow better distinguish or identify the proper way the power wire harness should be fastned to the motor? The existing power wires were both the same color and both the female and male connections for the power at the new motor were identical leaving you to guess which wire goes to which connection. After re-installing dishwasher, put about a gallon of water in bottom of unit prior to starting and then put it through a few cycles. It has been working just like new. Suggest having a helper when removing and re-installing dishwasher from under kitchen counter to assist with the power cord, water line, drain line, and help to turn the dishwasher upside down and right side up again.
