SHE4AEM2N/01 Bosch Dishwasher

replacing the sensor was simple, just unplug and turn it out, but didn't solve the problem, it's a float sensor that doesn't show up on the tech sheet in the dishwasher or anywhere in troubleshooting on the internet I could find.

Remove the dishwasher from under the counter. Remove door springs. On the inside of the lip of the door remove the 6 screws that hold the outer door panel on, and remove panel. this will expose hinge screws. Remove the two screws per side holding the inner door to the hinge assembly. Take pictures of the way the gasket's grey plastic end ... Read more cap assembles between the inner door frame and the hinge, and remove the inner door. The old gasket has a channel lip that sits on the plastic edge of the washer tub, pull it off this lip and discard. Install new gasket and put it all back together! Use this opportunity to clean the gunk out of the upper door seals.

I watch utube to assess the problem then took eveything apart and saw the build up on the filter, which i had never cleaned. I tried to clean it but was unsuccessful so order the filter from partselect and it came within a couple of days, installed very easily and began to clean as it always had.
