No power to washer/dryer

[Bakersfish]

2020 Montana 3761RL.

I have no power to either socket in the closet for the washer/dryer. I've checked the circuit breakers; tripped them and returned back to the on position. I bought a tester for sockets and every other socket works but the washer/dryer in the closet.

Any ideas??? What could I be doing wrong or is there something I need to do to activate these circuits?

We're in Casa Grande Arizona for a couple of months so we really need the washer/dryer.

Thanks...
