We have a Bosch dishwasher that seems to run fine when washing dishes, but for the last several weeks has been filling with water over the next several hours after it runs, which then leaks out when the door is opened. It is more or less dry after it runs, however. We’ve also noticed that every hour or so when the dishwasher is not otherwise running, it sounds like something (the pump?) is spinning up for a couple of seconds- we don’t recall that happening before the water-filling issue started. I’ve cleaned the filters, and checked all the drainage tubes and they seem to be high and looped as they should between the dishwasher and the disposal. We’re not sure where the water is coming from, or what part is spinning up.
