Washer, Dryer and Dishwasher Circuits for a Downstairs Unit in Vancouver, WA

Adding a laundry and a dishwasher to a downstairs unit is three dedicated circuits and one protection question. On this home in the Vancouver area, Newman Electric ran all three and sorted the GFCI at the same time, permitted through the City of Vancouver.

Why each appliance gets its own circuit

Washer, dryer and dishwasher are the three appliances people most often try to share a circuit with something else, and all three are bad candidates:

• A dryer is a 240-volt load running near its rating for an hour at a time. It never shares.
• A washer draws hard on the motor start and typically wants its own 20-amp circuit, especially in a laundry where the two appliances run together.
• A dishwasher runs unattended, often overnight, and it heats water. A nuisance trip on a shared circuit means a full tub of standing water and a service call.

The general principle behind kitchen and laundry circuits is the same one that applies to any fixed appliance: if it draws hard, runs long, or matters when it stops, it gets a home run.

GFCI beside the dishwasher, deliberately

The countertop receptacle next to the dishwasher got GFCI protection added.

Kitchen counter receptacles have required GFCI protection for a long time, and the requirement has expanded over successive code cycles to cover dishwashers themselves. But the practical reason is simpler than the code reason: it is a receptacle within arm’s reach of a sink, in a room where hands are wet.

If you have ever had one trip and not known how to bring it back, our guide to what to do when a GFCI will not reset walks through it.

The wall opens only as far as it has to

The laundry rough-in meant opening a finished wall, and the size of that opening is a real part of the job’s cost to the homeowner. Not our cost, theirs, because whoever patches and paints is charging by the square foot.

Cutting a controlled opening between two studs, setting the boxes, and leaving a patch that a drywaller can close in one pass is worth the extra care at the time. A rough hole is faster for the electrician and more expensive for the customer.

Permit, on interior work too

This one went through the City of Vancouver rather than L&I, because addresses inside city limits are the exception to the county-wide rule.

New circuits are permitted work whether or not anyone would ever notice. Skipping it saves nothing and turns up later, usually during a sale, usually at the worst moment.
