Paul for Model Number WDF560SAFM2 My dishwasher wasn't cleaning properly, so I'm attempting to self repair. Initial symptom I noticed was that the detergent pod was not fully dissolved and lying on the bottom of the dishwasher. Error code I keep getting is F4E3, which refers to the wash pump. I also received an F9E1 at some point referring to the diverter motor. I have tried: - Replacing the wash pump. No change. - Replacing the control board. No change. - Replacing the diverter motor. No change. I have determined that the washer is filling, draining, and heating. The wash pump works as well, as I can hear it spraying periodically. The problem is that the diverter does not stop at the proper locations. It *can* stop but it just doesn't, so during cycles where either the lower wash arm or upper wash arm should be spraying, it just keeps going back and forth with lots of down time inbetween as the diverter turns. I have verified that the diverter position sensor switch is working properly, and all fuses are OK. Is there some sort of sensor that could cause the diverter to continue to turn even though it has passed the correct location for a wash zone? I'm an electrical/computer engineer and this is driving me crazy! :)
Answer Hello Paul, the control board will power the diverter motor to the correct position to send the water from the circulation motor to the required spray arm, once the control board confirms the diverter is in the correct location it will then power the circulation motor power for a specific time, then cut off the circulation motor and power the diverter motor to the next position, and again power the circulation motor this repeats throughout the entire wash cycle, the control board's internal timer stops counting when the diverter motor is moving. Since the problem is still occurring with those new parts replaced something is interfering with the data communication between the diverter motor and the control board, I would suggest a close look at the turbidity sensor mounted to the side of the sump housing and esp the wiring to it, if the wiring is not damaged/wet/corroded, disconnect it and run a wash cycle and see if the problem reoccurs. if it does not, replace the sensor W11084121, if it again reoccurs there may be a wiring harness problem, the harness is W10834774.
