Noisy Whirlpool Dishwasher GU1200XTLB3
« on: December 27, 2011, 09:09:27 AM »

Whirlpool Dishwasher Model GU1200XTLB3

The customer was complaining about the dishwasher getting noisy.
Removed the access panel below the door and noticed it had been dripping water towards the back near the motor.
Ran the dishwasher and could tell the noise was coming from the motor.

Replace the motor part # AP4434021 to repair the noise and leak.

I carry just the pump motor.  It's a smaller box and fits both the large port and small port sumps.  It only takes a few seconds to replace it once the sump's out.  And just a couple of minutes to pull the pump cover, clean it out and check the check valve and chopper .

you have a point, but new pump/motor kits come with new tub seal, new style 4 blade chopper, & top housing. just feel better putting in for customers.
