A NEMA 14-50 (240 volt/50 amp) outlet, compatible with many EV charging cables, is present in the utility room to allow for charging of an EV parked at the top of the driveway.
It is controlled by the right-most "light" switch adjacent to the front door of that same wall.
Four things to check:
Is the dishwasher on? Its on/off button is at the upper left of its front door.
Is the switch on the wall above the dishwasher on?
Is the GFCI outlet to the right of the sink on, ie., not tripped?
Is circuit breaker #8 of the circuit panel (in the utility room) on?
