Do-It-Yourself Stories from Customers like You Upper spray arm not getting dishes clean   Scott G. • San Diego , CA • May 01, 2016

1. Removed and replaced circulation pump. That didn't end up being the whole problem, although there was debris jammed up in multiple sections of the impeller. Still was satisfied with results. 2. Continued trouble-shooting and discovered a lot of additional debris in the spray arm itself. Score! That resolved all performance issues. 3. In hind sight, I realized the strainer was warped and was allowing the debris to penetrate all of the critical areas. Ordered new strainer and it fit up flush... Read more

  • Helps prevent drips or seepage during fill and wash
  • Supports correct venting to keep moisture contained inside the tub
  • Common failure signs include water on the floor near the unit, dampness around the inlet/vent area, or a cracked, flattened, or brittle seal
What's included
  • One air/water inlet seal
Install notes
  • Disconnect power and shut off water before servicing
  • Access method varies by model; remove the inlet/vent cover or side panel to reach the seal

Genuine Whirlpool part
By: Whirlpool
Part Number: W11175758

This replacement silverware basket holds forks, knives and spoons in the dishwasher lower rack so utensils stay upright and separate for better cleaning and easier unloading. It's a direct-fit interior basket designed to restore secure utensil loading. What it does:

What's included: One silverware/utensil basket Install notes:

  • Avoid overloading; place sharp utensils point-down or bundle separately to reduce hazard when unloading
  • For appliance repairs beyond simple replacement, disconnect power and water before servicing

Do-It-Yourself Stories from Customers like You Our dishwasher was not cleaning the dishes no water pressure it seemed   Melissa F. • Falls Church , VA • June 06, 2015

That center piece was lodged under the heating element and was now somewhat beaten and melted. We looked on line for an illustrated parts breakdown and found it on Appliance Parts Pros website. The diagram was so clear and straight forward that it was easy to see the part that we needed and another part (when we looked) we also found missing. Well, 3 days later the parts came in...
