I've had this washer for maybe 6 months, working like new since I got it. When I was loading it yesterday, it started to beep randomly, as if I was pressing the start button. It ran the cycle fine, but continues to beep occasionally even if no one is near it. Hoping it's just a failing start switch or some dumb thing? There doesn't seem to be evidence the switche may have been splashed, no leaking evident on the floor either...
