Worked on a Scotsman SLE300 machine today. First thing I check on any Hoshi or Scotsman is the bin control. So I put my meter across it, and it's closed. Ok, that's not the problem. So I stare at the wiring diagram till I'm blue in the face, think I have it figured out, and maybe it's a defrost t'stat stuck closed, energizing the K1 relay. I pull the wire from the DT and the unit starts and freezes. It goes into harvest and stops after a minute (because of the wire I pulled off the DT). For the life of me, I can't figure out what the K1 relay is for. I gotta be missing something.
So...I go on the internet (luckily the customer is hooked up), and I find that the bin control needs to be OPEN to make ice and I'm looking at the diagram all wrong. What the hell Scotsman? Who ever heard of such foolishness?
Even their manual on the web is screwed up. In one place it tells you it needs to be closed. Another place it says it needs to be open. Boy did I feel silly.
