GU1200XT not getting dishes clean

[Team Irish]

I have a Quiet Partner GU1200XT that I bought from a neighbor that is not getting the dishes clean. It leaves food and a residue on the dishes.

I checked the spray arms which seem to be fine. The water is getting very hot and the pressure in our house is very good.

Last month I replaced the check valve and the chopper, but this hasn't helped.

What else could be wrong?

Hi,

GU1200XT is just a partial model#, whats the complete model#? The model# tag is located inside the dishwasher on the upper tub walls.

Sounds like you will need a new motor. Whirlpool had a few issues on that model with the motors.

You can order just the motor alone, or the motor/sump assembly which is higher in price, but easier/less steps to install.

Thanks,

Here's the sump/motor assembly for your model:
Part#8535150

Here's the motor alone:
Part#8534942

Here's the repair manual for your model, it explains how to change both:

Thanks Jake. How much harder is installing just the motor? My husband and I are both quite handy.

 

[Jake]

Its not to much harder, just takes more time and abit more involved, but if you follow the instructions in the repair manual, you should have any problems.

Is there a way I can tell for sure if it is the motor?

 

[Jake]

Sometimes, check the motor impeller, does it look worn out or beat up? Is the motor impeller stripped from the motor shaft, free turning on its own?

Jake

 

[Team Irish]

The motor impeller looks fine and it turns freely.

Ok, from my experience on these models, installing a new sump/motor assembly usually fixes the problem 95% of the time.

If you order the sump/motor assembly from the link I posted above and install it and it doesn't fix the problem, you can return it within 30 days for a full refund.
