Richard D Middleburg , FL December 07, 2015 Appliance: Maytag Dishwasher MDB8600AWW Maytag Dishwasher Mdb8600aww: Water was not draining all the way. How to replace Drain Pump. I had to pull the dishwasher out of the cabinet and tip it back to access the pump. The pump was held in place by a single T20 Torx fastener. Once that, the drain hose, and the electrical connector were removed, the pump came out with a 1/4 turn twist. I had to swap the retaining bracket over to the new pump. Installation was reverse of the previous steps. I reinstalled the dishwasher into the cabinet and ran a rinse cycle to test for leaks and make sure it was draining all the way. Everything checked out good. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
