My washer has been giving me trouble. First,hardly any cycle would work on it's own. I would have to keep turning the timer selector and jiggling it also. I bypassed what the wiring diagram called the check switch. Now everything works except agitate goes right through rinse and spin. If I turn it off when it reaches rinse or spin and turn it back on it will rinse /spin. Thinking timer,but know it's easy to misdiagnose. Would like any input I can get before deciding to buy a timer.
