I am currently using a Sorrento Michelagelo 2 group head machine. We bought it off an auction (shoestring budget for a coffee shop), we replaced the right solinoid about 3 months ago. Yesterday the group heads both stopped working, found a fuse was blown, replaced x3...keeps blowing fuse, and will not work! Everything else works fine. Does anyone have any suggestions............we have a huge event coming up tomorrow night!!!
