Welcome to the site,
And as far as a reset? I have not heard of one, but then I don't know it all either.
As far as the not draining, I did have the same issue with mine last year. The screen and tiny macerator at the bottom of the unit was blocked with a piece of glass. This made it so the pump would not kick on to drain the washer tub , it would work , then not work. Hope this is the problem, otherwise it sounds like there may be a short in the board.
