Shawn L Webb City , MO September 19, 2014 Appliance: Model MAYTAG MDB8751BWB Broken impeller and motor seal had gone bad I had previous knowledge of how to dismantle the three or four major parts but didn't know how to replace the seal. Appliance Parts Pro had a number of very helpful videos that gave me everything else I needed to know. Dishwasher not only works great, it's more quiet than it has been in years! 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
