My dishwasher was leaking from under the toe panel. I think I found the problem but want to run a test run with the toe panel off. If it starts to leak, what do I need to do to stop the dishwasher safely? (I keep reading horror stories online about dishwashers not working about being opened mid-cycle.) Our control panel is hidden, so to stop the dishwasher I will have to open it mid-cycle. How to stop that beeping? Thanks!
