What's Happening
The AquaStop safety system detected water in the base pan underneath the dishwasher. The water intake is shut off to prevent flooding. Common causes include a damaged door gasket, loose hose connections, cracked tub, or excessive suds. This is Bosch's most common dishwasher error.
How to Fix It
Disconnect power and water supply. Remove the lower front panel to access the base. Soak up water with towels. Check the door gasket, all hose connections, and sump area for the leak source. Tilting the unit back 45 degrees can drain the base pan and clear the sensor as a temporary fix.
