I think the unit has a problem in the electrical panel. It seems not to start at all--no beeps or lights whatsoever. Then it starts up about 5 or 10 minutes later as normal. On one load yesterday, a bunch of beeps were sounding for about the first 5 minutes after it started (and different lights were going on and off). Every few loads, I have no problem at all. This just started about a week ago. The unit is about 6 years old, and I've never had a problem until now. Any ideas? Thank you!
