David E Sleepy Hollow , NY June 29, 2020 Appliance: Maytag Dishwasher MDB7100AWQ Maytag Dishwasher Mdb7100awq: No water circulation, would fill and drain but no spray. How to replace Impeller And Seal Kit. First took apart to confirm broken pump impeller. Indeed it was. Ordered the pump/impeller kit. Waited 6 days for it to arrive. Installed kit as shown on video. Believe it or not had an extra part, a flat plastic 5" disc which showed its self upon removal. Has extra washer after was done. Was for temp sensor change out. Had an old boss tell me if if ain't broke, leave it alone. I did. No problems. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
