New dishwasher needs power supply.
 
Hi,

Im installing a new dishwasher at home and noticed there is no power suply behind the counter so i`ll need to run power.

In the basement there is an receptacle on the wall right below where the diswasher will be. I don't use that outlet.

So my question is could I take the power from that outlet and run the cable thru the floor to my dishwasher? (120v dw) I know ther recomment runing the power directly from the breaker panel but I don't think there is any room left in the panel for a dedicated breaker.

Thanks

What else is on the same circuit as that recep?

I think it might just be another receptacle (TV and Playstation only) and a small ceiling light.

But I will confirm when I get home tonight. I need to remove the plastic tarp over the insulation to see where the wires go.

Dishwashers draw power. Check the kilowatt rating on the nameplate on the DW. It should read something close to 1.5 kilowatts. That's a decent size load. I would advise you to run a dedicated 20 amp circuit from your main electrical panel.

I agree. A 20A dedicated circuit is what I am using.
Try to find other circuits that can be combined to free up space in your panel.

Just want to add that the installation manual says:
You must have:
120-volt, 60 Hz, AC-only, 15 or 20 amp., fused electrical
supply.

If a 15 amp breaker is good that must mean the dishwasher doesn't take up that much power. (I will check tonight on the dw itself) Sounds much more efficient then older models.

The only information on the power usage of the DW is a sticker on the motor that says 120V 2.3 amps. No where does it say Kilowatts. Only on the EnergyStar sticker that says 350KWH/Year.

There is 3 recepticles and one ceiling light that I would like to chare the cuircuit with. The 3 receptacles together will never have more then a TV on it.

The biggest draw by far for a DW is the electric heater that heats the water (if selected) and dries the dishes (if selected).
Depending on your hot water temperature, and what setting it is on, the DW's own heater may or may not automatically turn on.

I believe my DW states 12A @ 120V. It was on a 15A breaker before I ran a dedicated 20A to it.

Thanks for your help everybody. I will hook it up to a shared circuit with the recpetacle for now since the basement isn't even finished yet so all the power will only be used by the DW and nothing else. When I finish my basement and set up a TV and what not, I will then give it a dedicated 20amp. For now I don't feel comfortable playing in the breaker panel and I can't really afford the electrician.

Thanks again.
