replaced motor & pump still doesn't wash

Dishwasher Repair

Hi Guys:
our dishwasher motor was making a lot of grinding noises and then it finally seemed to die - stopped washing, no grinding noise. So the repair person we called said we should replace the motor and pump assembly. We ordered from this site and did it our selves. However, once the water fills up - it doesn’t start washing, sort of acts like the old one we just replaced.
So the questions are did we make some sort of mistake or is there another part we should replace.
Thanks for your help.

Here is the tech sheet

Cannot tell if you made a mistake.
Also not sure what acts like the old one means.
Grinding? No Wash?

If no wash check that the motor is getting power when it should with a meter

Hi Denman:
the story so far:

  1. I tried bench testing the old and new unit by plugging the blue and yellow motor wire directly into the wall - they both just hum no apparent motor turning
  2. The person who told me to replace the motor&pump suggested that maybe I connected the wires backwards. With the way the connector is constructed I can’t see how that is possible: However just checking the Yellow motor wire was going to the dishwasher Green wire and the Blue motor wire was going to the black and red (one wire two colors) dishwasher wire.

I am beginning to believe both the old and new motor are defective.

Any other tests or suggestions,

Thanks,
Russ

You cannot connect the wires to the motor wrong.
It is AC so it makes no difference.
I assume that the motor came with a capacitor.
If yes then I agree with you that the new motor is no good.

Only other test would be to disconnect the capacitor and measure the motor’s windings with a meter.

Hi Guys:
The dishwasher nightmare is over. The issue was the new motor had a problem with one of the connector pins, the wire still had insulation on it and was not making electrical contact with the pin. I noticed it because the pin was loose - but at this point I called back the repairman who fixed the contact (no use risking burning down the house) - and viola it worked - I was this close to doing it myself.

There were many lessons here that I still need to work on.

  1. some how the replacement part needs some kind of checking before attempting to be installed - I noticed there was no inspection sticker or indicator from the supplier. Also be very careful of the return policy - some how the supplier believes even if they supply you with a defective item - there is no return after it is installed. I guess I really need to work with a local supply house.

  2. The other is figure out how not buy a unit that craps out in 1 year and 7 months - more investigation before purchasing

Thanks,
Russ
