I have a sears dishwasher that is filling with water then seems to do nothing until time to drain which does fine. then it also heats too. I have checked with a test light and there is power going to the motor but it doesn't seem to be running at all. I am pretty sure I need to replace the motor, and was wondering if I am going down the correct road, and are there any suggestions you might have.
Answer Hello Rusty,
This sounds like you are right on the money. If voltage gets to an electrical component but it gives no response, it is usually bad unless the neutral line is not getting to the component to complete the circuit. You can test this by going from the wire that showed you the voltage to the other lines to the motor. When you hit the neutral, 120Vac should show on the meter. If you never get 120Vac to show up, you need to trace the neutral line back to the supply to ensure that side of the circuit is complete.
Can I purchase just an impeller assembly for motor number 154700101 or do I have to buy the whole thing.
Unfortunately the manufacturer does not provide the impeller as a separate component and you would need to replace the complete motor assembly.
dishwasher has slow leak coming from the righthand portion of the motor assembly that is white plastic. Part #AP5272221. This slow drip runs down the side of the plate that is screwed into the bottom of the dishwasher with 2 star screws. Could this be seals, the housing, etc. there appears to be a small hole in the opening in the white plastic area, is this normal ( like a pressure releif ? ). Dishwasher runs find and drains fine, just the agrivating leak that needs to be wiped up each time it is used.
Answer Doug, If water is leaking from the hole in the pump, that would indicate the motor shaft seal has failed, the is usually referred to as a "weep hole". If the water is leaking from around the black portion of the motor or bracket, you'll need to check or replace the "O" rings and check the pump housing for cracks in the screw holes, the bracket shouldn't be an issue, but it applies pressure to the seals and secures the pump motor to the housing and forces the motor to seal to the "O" rings. Make sure the Torx screws are tight and not stripped when installed and tightenned.
