My Bosch dishwasher, model SHU3307, 6 1/2 years old, continually fills and drains. when its draining, its sounds like its in slow motion. Looked ant the troubleshooting manual posted and its listed, but doesn’t say what to do to repair.
The first thing I would do is remove the toe panel and check for a water leak and water in the base.
