Jeffrey T Columbus , OH December 12, 2014 Appliance: Model 665.13769K602 Dishwasher making loud grinding noise when running It wasn't the food grinder. Ordered new circulation pump & motor assy. Videos are exactly to the point on the steps involved. Be sure to use liberal amount of water to lubricate the seal otherwise it will be a very tight fit. Also when tilting the unit back to insert the retaining clips back into the pump I found it helpful to only lift the unit at a very slight angle - just enough to get underneath the unit. Placing the unit on its back a few times caused the seal/unit to pop out - making the insertion of the retaining clips impossible. Helps to have an assistant in this step - it's not too heavy. Unit runs extremely quiet!!! This supplier - when they brag about shipping times they have every right to. I ordered the part Sunday night and it was delivered via FedEx on Tuesday!!! This was REGULAR shipping too!! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
