Matt for Model Number WDT720PADM0 My dishwasher won’t clean dishes and the soap just drips down the door unused. I checked the resistance of the OWI sensor via 12.1 and 12.3 on the harness. It was an open circuit. I confirmed continuity is good on the wires between the board and the sensor. I replaced the sensor but had the same results from the test. Replaced the sensor again fearing I got a bad one, but still has an open circuit. When performing the service diagnostics, I’ll sometimes get an F6, E6 error and sometimes won’t. The clean LED does not come on when it should in intervals 15 and 12 but it does come on in interval 4. What part do I change next when everything says the OWI sensor is broken but it’s not?
Answer Matt, if the OWI sensor was being tested via the wire harness W10850395 for the new one as well, it would be likely that there is a wire harness failure that is occurring during the opening and closing of the door. If the meter being used is not an auto range meter, it would need to be set to a reading level just higher than 52K Ohms. Another thing to check if the circulation motor is operating would be the jets of the spray arm. If the jets have a clog, it can affect the water being able to spray into the dispenser when the detergent door is opened. Read More... Answered by AppliancePartsPros.com | Monday, November 28, 2022
