Hi, I have a Manitowoc S-series ice machine. Model SY0304A Serial 110620428. It makes 5 or 6 batches of ice just fine. But then... usually when I'm not around... it will stop making ice. I take the front cover and water curtain off and the ice tray is frosted over. It is as if the ice tray freezes as it should, but no water is flowing over it to make ice. I can hear the compressor still running, but the fan cycles on for a second or so every 10 seconds, approximately. I was thinking perhaps the water pump was faulty, but it works just fine after I thaw off the frost and restart it. I am not getting any error codes behind the service panel. I am baffled by this problem. I am attempting to get service, but it is looking like I'm going to have to do it myself, as the machine is at my fishing camp in the middle of nowhere. I have cleaned the machine by the book. I'd apprieciate any help. Thanks!
