How to Troubleshoot & Replace Bosch AP2802390 / 00263185 Level Switch Assembly

Access required removing the panel on the left site of the dishwasher. I noticed that the small red plunger on the microswitch in the level switch assembly was not returning to its fully extended position when released by the blue lever. This meant that the dishwasher "thought" it was full of water when it was not. Some experimentation confirmed that. Once I had the part it was a simple matter of snapping out the old part and snapping in the new. The only tools required were those to release the dishwasher so it could be pulled out from its niche and to remove the left panel. The part exchange just required a screwdriver to bend a plastic tab that held the part in place. By the way, the part arrived the day after I ordered it. Nice surprise.
