I'm uaually working on cars but I find myself trying to diagnose my washer. It fills, agitates fine, but then no draining, spinning or even a sound. I took the timer apart and found 2 contacts melted. I installed a new timer, now it does the same thing as before, except if I jar the machine it starts draining and spinning at the same time and works normally until it finishes the rinse agitation, then it all happens again until I jar the machine again. I don't know where to check next. Please help.
