The dishwasher started making a loud howling noise during the wash cycle and it is progressively getting louder and louder. Everything on the dishwasher works fine. What part do I need to replace to make this quiet again?

[Gene]

Remove the pump cover and the inlet protector (#8 on the pump & motor break down diagram) and check for a broken glass or any other foreign objects inside.

Here are the break down diagrams for the Whirlpool dishwasher Model GU1500XTLQ2

Gene,

Thank you for your advice. I followed your instructions and did not find any foreign body or anything else that I could see wrong. Still makes that loud noise. Any other suggestions?

[Gene]

Remove the chopper assembly (#6 on the pump & motor break down diagram) and check if it's not broken. If there is nothing wrong then the motor assembly has to be replaced.

Gene,

I will check that next. Is the motor assembly with the last model number digits of Q2 the same as model number Q3 that I have?

[Gene]

Yes, this is the same motor.

Gene,

Checked the chopper also and could not find anything wrong, but since I put it all back together, it seems a little quieter. It might just be wishful thinking on my part!! Thanks for all your help. I am sure I will be ordering that part from you soon. You definitely have the best prices.
