Dale J Battle Ground , WA December 31, 2018 Appliance: Maytag Undercounter Dishwasher MDB4630AWS5 Maytag Dishwasher Mdb4630aws5 / : Failed dishwasher motor pump assembly. How to replace Pump And Motor Assembly. Replaced pump and motor assembly with new unit. The instructions in the APP repair video were excellent and made the job much easier. Disconnecting and reconnecting the hard wired electrical connection was probably the hardest part. Everything else was pretty easy. The new pump and motor assembly works great and the dishwasher is back to sounding like the dishes are being power washed instead of gently sloshed about in a bucket of water. I'd forgotten how loud that Maytag was when it was running well. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
