Bosch dishwashers are among some of the quietest in the industry. They also feature a number of different dishwasher models, including recessed handle appliances, stainless-steel construction and economical washing modes. Before you start with your Bosch dishwasher wiring, it's a good idea to become familiar with how dishwashers operate in general and why they require electricity.
How a Bosch Dishwasher Operates
Bosch dishwashers operate similar to other types of dishwashers. Water from the home water supply flows into the dishwasher after the inlet valve is opened. This water mixes with soap inside the cabinet, and this soapy mixture is then pumped through the sprayer arm and onto the dishes. This soapy wash is then followed by a rinse with plain water. In between the cycles, the used dishwater is pumped out through a drain hose and into the sewer system.

Dishwashers and Electricity
Dishwashers need electricity for a number of different functions inside the appliance. First and foremost, electricity controls the circuit board, or brain, that times the dishwasher cycles. Electricity is also used by the solenoids, which convert electrical energy into mechanical power for opening and closing the water inlets and drain switches. The pump that moves water into and out of the appliance also requires electricity to operate. Lastly, the heating element inside the dishwasher that dries the dishes needs an electrical supply to operate.
For operation in the United States, most Bosch dishwashers run on a 120-volt, 12-amp circuit. You will need to run an electrical line to your Bosch dishwasher location from a dedicated circuit at the main breaker. This type of job is beyond the scope of most DIYers and should be done by a qualified electrician. Depending on your dishwasher model, the electrical supply line should either end in a three-prong plug socket or in the typical live, neutral and ground three-wire circuit for connecting to the appliance directly.
Wiring a Bosch Dishwasher
To wire your Bosch dishwasher, begin by removing the lower kick panel with a screwdriver. Locate the electrical wiring box, which is usually positioned beneath the front of the cabinet. After removing the wiring box cover, connect the black wire from the home circuit to the black wire inside the electrical box or the terminal marked "live." Then connect the white circuit wire to the white wire inside the box or to the terminal marked "neutral." The bare copper wire should be connected to the green wire or to the green-colored screw marked "ground" inside the wiring box.
