What was the solution? I am in the same situation, well, not mid cycle, so no water in it, but won’t power on. Connections are good, breaker is good. Was this solved for you?
Try unplugging and plugging it back in it should reset itself. If that new you should have a two year warranty at least. Check for rodents, the breaker and the power level. Double check vuse panel n unplug anything that takes alot of power when trying to restart.
