Dishwasher wiring question
My dishwasher is on a switch for exactly the reason stated above, in some jurisdictions a visible disconnect is required for a dishwasher. Since you already have the switch, and the switch is (presumably) in an approved box, it should be a simple matter to install wiring from the switch directly to the dishwasher. There is no reason to go to the trouble of installing a plug on the dishwasher, there is a rated box on the dishwasher, typically in the lower right corner, where you make the connections between the circuit from the switch and the dishwasher. The only downside of the hard wired arrangement is that if you need to pull the dishwasher, you have to disconnect the wires from the box, but the only reason I can think of to pull the dishwasher is to service or replace it.
