Jeremy W for Model Number 665.12723k310 Kenmore dishwasher will fill and drain, but will not spray during the wash cycle. Sump assembly (not motor) and diverter motor have been replaced. After the sump assembly was replaced (because of a leak), the dishwasher stopped spraying. I replaced the diverter motor, and the dishwasher sprayed for about a second and stopped spraying. It went through all the cycles, and filled and drained, but would not spray.

Also check the wiring and make sure that there are no damaged or loose connections. Read More... Answered by AppliancePartsPros.com | Wednesday, November 15, 2017
