Steve for Model Number 665.14743N510 The dishwasher starts and runs. The upper rotating washer rotates. The bottom rotating washer does not rotate.
Answer Steve, the lower spray arm W10859935 will need to be inspected for any clogs or debris that may be preventing it from rotating. If the spray arm checks good, then it is possible that the diverter motor W10537869 may have debris stopping it from rotating and can be checked by removing the spray arms, water tower, and the spray arm base. If there is a clog, it will need to be removed. If there is not a clog, then it is likely that the motor is not rotating due to either voltage not being supplied or the motor having failed. With the unit assembled, the diverter motor can be tested for 120VAC from the main control at connection P7 pin 4 to P7 pin 6. If there is 120VAC within the first few minutes of a cycle, then the motor has failed. Read More... Answered by AppliancePartsPros.com | Tuesday, November 19, 2019
