Gregory P Mansfield , OH January 01, 2017 Appliance: Maytag Portable Dishwasher MDC4650AWB0 Maytag Dishwasher Mdc4650awb0: Flappers on docking station were worn out and/or missing also the pump filter fabric was torn so a new pump filter was installed as well. How to replace Docking Station. Dishes were 'gritty' with an almost invisible coating of specks smaller than grains of salt. Prior to ordering parts, I had to determine which part(s) needed replaced and which could benefit from a good cleaning. After viewing Appliance Parts Pros YouTube Videos, I removed the Main Manifold (snaps right off) including the Top Spray Arm. I discovered the Flappers of the Docking Station (AP6009888) were worn out and/or missing. I removed the Docking Station simply by popping the old one off the Main Manifold. The new one snaps right on (no tools needed) but prior to installing the new Docking Station, please remember to install the new Flappers. The second portion of my repair involved the Pump/Motor/Impeller area. The only tools required were pliers to remove the plastic Washer Arm Cap, which then allows removal of Lower Washer Arm. Also, a Number 15 (#15) and a Number 20 (#20) Torx screwdriver/socket were used to remove screws from the Filter Plate, Outlet, Impeller, and Filter Assembly. Upon inspection, I discovered that one area of the mesh/fabric screen of the Pump Filter (AP6016649) was torn. The replacement part part was ordered while all others were treated to a thorough and careful cleaning. Kudos to appliancepartspros.com! My parts arrived sooner than expected even though I chose Standard Shipping. I am very well pleased with Appliance Parts Pros instructional videos, their quick shipping, and their excellent quality parts. My dishwasher, even though more than 12 years old, is performing as good as new, as evidenced by my ultra clean dishes!! 38 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
