Chosen Solution
I did a load of clothes and noticed a constant sound coming from the machine. I checked the end of cycle button and it goes on and off..but the noise is still there. I unplugged it for about 15 minutes and plugged it back on and the noise comes back. The wash cycle did okay, it’s only the constant beeping.
It’s an issue with the control board. See the answer by jjw6455 here for a $10 fix: http://www.applianceblog.com/mainforums/…
