Hello, Thank you for using JustAnswer! If you have any questions after reading my answer,be sure to let me know.
From what you are describing it sounds like your washer will not come back on after the power failure. The washer does not have any type of a reset switch. Be sure the plug is good & the breaker did not trip. Unplug the washer & plug in a lamp or something to verify the wall outlet is still good. If the washer is still not coming on I would recommend calling a service technician to diagnose & repair.
You will need a hands o tech on location to run circuits testing
