My washer sometimes stops during filling, won't advance to the next cycle, or quits in the middle of the cycle. If I push start it starts at the beginning of the wash cycle unless I put it on rinse or spin. It does not pick up where it left off. I had the timer replaced on it about a year ago but it started acting up again after about four months. It has progressively gotten worse. It may complete a whole wash/rinse/spin cycle one time out of five. Do you think it is the timer again or another part?
