San Marino Lisa 2 group problem
I have a San Marino Lisa 2 group machine installed in my coffee van... Been running fine - however yesterday it kept running one of the programmed buttons intermittently all day. It was only my the one button, and only the one (right) group head. Sometimes it would run on/off constantly for a few minutes. Sometimes once every half hour. I reprogrammed it to run and stop instantly just to get me through the day with manual pouring of shots.
Anyone come across this before? Is it just a faulty switch panel?
