Machine won't stop after final spin. Starts wash cycle over and over again until it's unplugged or manually stopped by pressing and holding lid-unlock button. Was able to open lid while machine was in operation. Not supposed to do that! Clothes are wet because cycle has started to refill tub again. Any solutions to this issue?? I replaced the drain pump thinking it was a bad drain pump but the old one checked out fine. Bad control board? Worth fixing? Buy new machine?
