If your Bosch dishwasher is showing an error code of E:01 then the motor controller in the power module has gone bad and you will need to replace the power module.
How To Replace Bosch Dishwasher Power Module
Tools needed: T20 Torx, # 2 Phillips and flat blade screwdriver.
1. Turn off the power supply to the dishwasher.
2. Remove toe kick panel.
3. Disconnect and pull out dishwasher.
Power modules are located in the base on the right side of dishwashers, not behind fascia panels. So: Dishwashers must be pulled out to change controls.
4. Two plastic base tabs hold the power module in place. To remove power module, gently pry tabs until they clear module (below left), move bottom of module (in toward heat pump) until it clears base (below right) and pull module from base.
5. Pry cover tabs to open cover (below left), then disconnect wire harnesses from power module (below right).
