William S Brown Deer , WI August 25, 2015 Appliance: Kenmore Undercounter Dishwasher 66516592201 Kenmore Dishwasher 66516592201: Pump motor was making noise (bad bearing). How to replace Dishwasher Circulation Pump Motor. I replaced the pump. I ruined the old motor after I replaced the pump to see what was the problem. I found that water had passed the seal and rusted the motor shaft and water got into the bearing and caused the noise. I don't think I could have replaced the bearing without damaging the shaft and motor. I would have wasted money on the bearing and seal and ending buying the motor. The motor was very simple to replace once I got the washer out to work on it. It took about 5 minutes to replace the pump. 45 minutes to remove and reinstall the dishwasher. The pump I purchased was a perfect fit and the washer runs like new. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
