Have your alarm systems on those machines worked well for you?? One of my machines is a revolution and I unhooked all the alarm systems 21 years ago. It seriously drove me nuts. Not one time did it have a legit alarm - every time they were false alarms and they’d shut the wash down costing me business. I have had zero problems since I unplugged it all. I have fantastic cameras and I can tell from glancing at my screen on the wall in my living room - or from looking at the cameras in my cell phone - that all is well.
