Listing the symptoms did not find the solution on the diagnostic portion of your website however reading your customer comments did allow me to match into the Turbidity Sensor. It solved the problem. Sensor install on the KDFE104DWH2 KitchenAid dishwasher for me was much easier than your install video. Instead of disconnecting and unscrewing the entire disheasher and then laying it on it's back the install was simply reach under from the front. To be clear it took days checking spray arms, filters, water level switch and reading diagnostics web sites. The diagnostics was 6 out of 10 difficult. Installing the sensor was 2 out of 10 difficulty.
