Sorry for the delay in responding but I had plans and left my house yesterday afternoon and just returned. Unfortunately, the information you provided didn't resolve the problem. I was eventually able to figure it out on my own. There is an end cycle button on the panel that can apparently lock on unlock control of the washer. If the button is held for 3-5 seconds, the machine will lock or unlock and I must have mistakenly leaned on the button to lock it in the first place.
