It started making high pitched electronic noises after the second year for a few months.
Now it beeps 3 times and all the lights on the control panel stay on. This started happening about 6 months ago every week. It's been good for about 3 months and just this week has happened 3 times.
I first unplugged then plugged it back in and it reset. Today I left it and it reset by itself in about 1 hour. Not sure what to do or what's going to happen next...
