Power connected to dishwasher isn't tied into breaker panel - now what?
Here are a couple of ideas. Usually there is a service panel on the outside of the house, this is where the main service line connects to the home. There should be a few breakers in there, but they are typically only for the bigger circuits. At my house for example, there are breakers in the outside panel for the range/oven, dryer, air conditioner, and one that goes to my main circuit panel inside. The inside breaker box is where all the breakers for lights and outlets inside are. Some homes get a second panel added inside when they run out of space on the primary panel. So I'd try to see if you have another circuit panel inside, or check in your outside panel to see if there is a circuit there that will shutoff the dishwasher circuit.
