Seth for Model Number ldf7774st Top sprayer for utensils stopped moving and middle rack is not cleaning as well. No error codes. Replaced the diverter motor and noticed no difference. Both the original and replacement ohm out at ~4 ohms Checked wiring and didn't see anything suspicious. Does the diverter motor get a constant voltage supply during a normal wash cycle or is it cycled on and off? At this point I am thinking its the control board not telling it to move. When I run the diagnostic test it will briefly show Cr and then Lo from then on out.
Answer Seth, Check those spray arms for clogs and the lines up. If that is all good it would likely be the diverter motor. Read More... Answered by AppliancePartsPros.com | Tuesday, February 15, 2022
