How to Troubleshoot & Replace Bosch AP4339677 / 00645147 Water Inlet Housing

1. I tested the water inlet valve and there was no continuity. I then bought the water inlet valve and replace the the bad unit for the new part. 2. I then place the dishwasher on an express wash cycle to see if the water inlet valve was working. I did see water entering the dishwasher tub by observing the water inlet housing. I let the cycle run for 5 minuted but did not observe the spray arms moving after opening the door. 3. My next step was to test the pump and motor housing unit. There was not continuity on the pump connector but the heater unit did not continuity. I bought the pump and motor housing unit and replaced the old unit for the new unit. I then ran an express wash cycle and after five minutes; I opened the door and noticed the spray arms moving. 4. Problem fixed. The Appliance Parts videos were spot on to help with the repairs. The store prices are very competitive with other online appliance websites. 

Unscrewed the cover on the inside of the washer on the left side. Pulled off the water inlet on the left side on the outside. Replaced water inlet and screwed washer back on. It was a little hard to pull off the water inlet but we managed. Very grateful this turned out to be a simple fix. 

Unplugged dishwasher and turned off water supply. Removed bottom front cover from dishwasher to access the inlet valve. Disconnected water supply line, water line from valve to dishwasher and the electrical connector. Removed old valve and installed new one. Connected electrical connector and water lines, put bottom face plate back on and that was it. Fixed.
