Because of the power it needs, a dishwasher should always have its own circuit, separate from the two individual appliance circuits that are often positioned above your countertop. Dishwashers run on 115-volt or 120-volt power. The dishwasher circuit should be a 125-volt, 15-amp circuit.

Unlike the plug-in appliances used in rooms beyond the kitchen, a dishwasher must be hardwired and hooked up to the home’s plumbing. If you’re up to challenge of installing it yourself, you can save real money.

The dishwasher circuit should be a dedicated 120/125-volt, 15-amp circuit. This 15-amp circuit is fed with a 14/2 NM wire with a ground. You may also elect to feed the dishwasher with a 20-amp circuit using 12/2 NM wire with a ground.

GFCI protection is not required for receptacles serving appliances like dishwashers, or convenience receptacles that do not supply countertop surfaces. Receptacles installed within 6 ft of the outside edge of a wet bar sink must also be GFCI-protected [210.8(A)(7)].

If you can meet the provisions in 210.52, and still end up under the load calculations in other parts of the code. AND the dishwasher is cord-and-plug connected, then it is possible to have the fridge and dishwasher on the same 20 ampere small appliance branch circuit.
