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

Adding a laundry and a dishwasher to a downstairs unit means three dedicated circuits and a GFCI. On this home in the Vancouver area, we ran all three and took care of the GFCI at the same time, on a City of Vancouver permit.

Why each appliance gets its own circuit

The washer, dryer and dishwasher are the three appliances people most often try to put on a shared circuit, and none of them should be:

• A dryer is 240 volts and runs near its limit for an hour at a time. It never shares.
• A washer pulls hard when the motor starts and needs its own 20-amp circuit, especially in a laundry where both machines run together.
• A dishwasher runs when nobody’s watching, often overnight, and it heats water. If it trips a shared breaker, you come back to a tub of standing water.

The rule for kitchen and laundry circuits is the same as for any big appliance. If it pulls hard, runs long, or you’ll notice when it stops, it gets its own circuit.

GFCI next to the dishwasher

We added GFCI protection to the counter outlet next to the dishwasher.

Kitchen counter outlets have needed GFCI for a long time, and newer code covers dishwashers too. The simple reason is that it’s an outlet within reach of the sink, in a room where your hands are wet.

If you’ve ever had one trip and couldn’t get it to reset, our guide to what to do when a GFCI won’t reset walks you through it.

We only open the wall as much as we need

The laundry rough-in meant opening a finished wall, and how big that hole is matters to the homeowner. Whoever patches and paints charges by the square foot.

We cut a clean opening between two studs, set the boxes, and leave a hole a drywaller can patch in one pass. A sloppy hole is faster for the electrician and costs the customer more.

Permit for inside work too

This one went through the City of Vancouver, not L&I, because addresses inside city limits are the exception in Clark County.

New circuits need a permit, whether or not anyone would notice. Skipping it doesn’t save anything. It just comes up later, usually when you sell, at the worst time.
