Machine intermittantly stops running at the end of an agitate cycle. It sets there with the water still in the machine. No noise, the timer isn't running, nothing. If I jar it the right way, or turn the timer to the next cycle, usually it will complete its function. Sometimes I have to fiddle with it, or jar it several times to make it continue. I'm thinking the timer needs to be replaced, but at $100. I'd like a pro's opinion. Thanks for your help. Al
