My work has an older Bosch dishwasher model which is having issues draining the water at the bottom after a cycle is complete. We had a repair person unclog the pipes a few weeks ago and the issue is still happening. The first time this happened I was able to force drain it by pressing down the first and fourth buttons on the right side control panel, but this is no longer working. All videos about this seem to be related to newer models. Image attached here for reference.
