Louis D Peabody , MA March 28, 2023 Appliance: Model DU1145WTPBA Noisy & then a low buzzing sound. Replace the circulation pump motor & chopper. The motor took ten minutes to change, but pulling the dishwasher out & in took two hours. The chopper gave me more trouble than it was worth. The unit is quiet & the dishes are coming out cleaner. Disassembled the motor & the front bearing had denigrated & the seal had been weeping for a long time. Great service from AppliancePartsPros.com. The motor was here in a day. I've used them before & will use them again! Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
