How to Troubleshoot & Replace Bosch AP2802373 / 00165256 Dishwasher Float Switch

I checked continuity at the float switch since I knew the inlet valve was working when direct wired to 120v. Switch did not have continuity. Replaced switch and inlet valve worked at start of cycle. 

Replaced water inlet valve and float switch after diagnosing using Bosch troubleshooting guide, logic, and physical inspection. Float switch was burned out. Inlet valve was making "dying coyote" noises. 

Replaced the float switch. 

I contacted AppliancePartsPros.com and spoke with Cindy concerning my dishwasher stopping mid cycle. I told her what symptoms we were having and what Error code (E17). Within seconds, her response was: "this is the part you need" (Water inlet). I ordered it and it arrived the very next day. Installed it following their installation video (took about 10 minutes) and our dishwasher is working like new again! They are an awesome company to deal with! 

Well once I realized that we were not getting any water into the washer I started looking up online for solutions. The end result led me to this site to try some parts. Searching for parts was a breeze with a online chat rep to help me locate what I needed. They were quick and spot on with there suggestions. Ordering anything online usually takes a full work week and maybe into the next to receive the parts. Not these guys! I had them in hand in roughly 48 hours after order! Long story short, the missus is super happy and so was I after the machine was back up running in no time thanks to APP. ~Kevin Jackson, Maine 

I purchased this new float switch device. Swapped it out, and we were back in business again. 

Since the website showed that 66% of the time it was the water inlet and 33% of the time it was the float switch, I decided to replace both, as the cost of the two parts together was less than it would have cost to have someone come out and diagnose the problem. I ordered the parts around noon on a Friday and received them by 3:00 on Saturday, without paying for any kind of express delivery. The videos on the website were perfect for showing me how to do the repairs, and the repair took less than an hour. 

I reviewed the AppliancePartsPros troubleshooting guide. The guide was right -on for the cause of my flooding. It indicated the fill valve was leaking. (While Not Activated). I watched the part replacement video. It was excellent. Suggestion: Replace the dishwasher fill line at the same time of your your repair. With a Burst-Prevention valve type line. If your dishwasher is 10yrs or older you risk having a line burst due to continued exposure to hot water. 

We didn't end up figuring out the problem. 

Using your helpful videos made the job go much easier. Thanks
