Do-It-Yourself Stories from Customers like You The switch stopped working   Kirk B. • Pelham , AL • March 24, 2014

Initially performed troubleshooting over the phone with Bosch customer support and did preliminary research on the web. Ultimately had to call out service technician to isolate/confirm problem. He confirmed the problem was most likely the switch (if not, the actually computer processor) and gave me the part number (since it was going to take 10 BD's for him to get the part). I ordered through Appliance Parts Pros and received the part in only 2 days. However, upon trying to install it, I... Read more

Do-It-Yourself Stories from Customers like You Bosch dishwasher would not finish the cycle   David C. • Morristown , NJ • October 23, 2019

I replaced the controller, the thin seal @ the top and the cable in the door and has seemed to resolve the issue. I removed the three screws that were in the upper part of the door handle slot and took out the inner panel screws on the door. No need to take the screws for the hinges out. The door will spring shut once you take the inner panel off so be careful. You'll need a Torx screwdriver Read more

I replaced the gaskets with products from this site which I would not have been able to do without the video on this site. Hard job. The leak was still there though, so I have some hints with this kind of washer. 1) There is a float switch on the base that turns on the drain pump when there is a leak, that is why the drain pump runs constantly, it prevents catastrophic flooding in many cases. The float consists of a little styrofoam donut that lifts an arm, all white. The arm is connected to a... Read more
