dishwasher is 2 years old, light duty and no prior issues.

contractor was doing some work in the kitchen and asked that i turn off kitchen breakers which i did. he completed his work which had no direct impact to the dishwasher. later i attempted to wash a load and the LED panel would not light nor would the dishwasher start. i do get a tone whenever i close the door.

the breakers are all in the on position. the tone would suggest i have power.

advice please.
