Home dishwashers commonly operate on 110 volts. This is the standard household current. Other considerations are the amperage of the dishwasher. Some dishwashers operate with a minimum of 15 amps while others utilize a 20-amp circuit. If the planned dishwasher operates on 15 amps consider a 20-amp circuit to allow for future expansion to a larger capacity dishwasher. The amperage of the circuit is determined by the breaker or fuse installed in the electrical utility box. The outlet for the dishwasher should be the only outlet connected to that fuse or breaker.
Ground Fault Interrupters, sometimes referred to as GFI or GFCI, provide an additional level of safety if the outlet becomes wet. The GFI trips, or disconnects the power at the outlet, before there is any electrocution danger. Building codes commonly require this kind of circuit in kitchens or bathrooms where water is present.
The simplest placement for the dishwasher outlet is under the sink. Most kitchen plans place the dishwasher next to the sink to allow easy connection to the water supply and wastewater drain lines. If the dishwasher is being placed elsewhere within the kitchen modify the outlet placement to provide for easy connection.
New dishwashers commonly arrive with the power cord not attached to the appliance. This allows the installer to trim the length of the cord to fit the situation. After cutting the cord fasten the wires to the terminals usually located at the front base of the appliance using wire nuts. Match the colors of the wire to the terminals or consult the manufacturer’s instructions if non-standard wire coloring is used.
