I'm trying to get my new dishwasher installed. My problem is I have no power at the outlet. It us a single Romex in the box. I've checked all the surrounding outlets and switches hoping to find the leg off to the dishwasher outlet, but I can find the feed to the dishwasher outlet. I tried to tone out the wire to the breaker panel but nothing. The breaker marked "dishwasher has power leaving so I'm essentially lost now. Any assistance would be greatly appreciated.
