Making repairs to your Bosch dishwasher might require some disassembly of the unit. The electrical components, pump and hoses are accessible through the bottom of the dishwasher. Like most dishwashers, the Bosch dishwasher has a removable bottom panel, called a toe panel, below the door. However, unlike many other dishwasher brands, a Bosch dishwasher also has a bottom base panel that connects to the dishwasher frame. Removing a Bosch dishwasher bottom provides the access necessary to make repairs to your dishwasher.
Go to your home electrical box and turn off the circuit breaker to the Bosch dishwasher. The circuit breaker might control all junction boxes on the same wall as the dishwasher.
Remove the two hex-head screws securing the toe panel to the bottom base panel, using a 1/4-inch nut driver. Pull the toe panel away from the dishwasher. There is a foam strip that sits under the base panel. Pull the foam strip out with your fingers.
Turn the screws securing the bottom base panel to the dishwasher frame counterclockwise with the nut driver. The screws are on each front end of the base panel.
Pull the bottom base panel down with your hands and tilt the bottom of the panel toward you. Continue pulling the bottom of the panel toward you, disengaging the top flanges of the panel from the dishwasher. All components under the dishwasher are now accessible.
