Question about Frigidaire 24 in. PLD2850 Built-in Dishwasher
Only makes noise when pump is running not when filling
HI. the circulation pump has an impeller that is attached to the drive shaft stud. this impeller has become unstable and, it is producing this noise you are hearing during the wash. you will need to replace the wash impeller asap.
there are kits available on-line or, you can initiate a service call for this as well.

Hi Andy and welcome to FixYa. I am Kelly. That loud noise your hearing is the motor bearings. If you were to remove the lower kick panel you will prbably find signs of a slow leak of water has been trickling through the motor and you will see a water spot under the motor pump assembly.
You were correct in your assumption that it was bearings. What happens is the motor shaft ceramic seal starts leaking long before the home owner even notices it. Then the water gets into the motor and corrosion starts to build up. As the motor turns the bearing starts to spal as a result of the corrosion and you hear the loud noises.
The only fix for this sadly to say is a complete motor impeller assembly replacement. If your model number is the one associated with this post / question: KUDI01FLSS then there is one more digit after the last "S" that being one of the following numbers 0, 1, 2, 3, 4, 5 or 6.
The motor and impeller for your dishwasher Item 10 or 18 can be found here and is listed at $138.44:
The seal that has failed is item 23 of the same link. Changing the seal at this point will not stop the noise.
Thanks for using FixYa.
