Steve W Frederick , MD November 18, 2019 Appliance: Frigidaire Dishwasher FDB1050REQ0 Frigidaire Dishwasher Fdb1050req0: Circulation motor leaking. How to replace Dishwasher Sump Gasket. Following the great video on the site, I pulled the motor off and was about to put the o-rings on when I noticed there was rust on the motor shaft. Very close inspection showed the o-rings were still good. Not having time to order a motor, and a local store was having a sale, I replaced the whole unit. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
