A Bosch dishwasher that has no power is not necessarily going to be a big problem. There are several reasons why the dishwasher may have no power, and many of these reasons are fairly simple to diagnose and easy to fix. The Bosch dishwasher owner's manual provides dishwasher owners a few tips about ways they can troubleshoot their dishwashers if they have no power.
Push the door to close it completely. The dishwasher will not run unless the door is latched.
Press the main power switch on the dishwasher's front panel. The switch must be pressed for it to receive power.
Check the circuit breaker to ensure that a switch was not flipped to cause the appliance to lose power. Flip the switch back to the "On" position.
