Hi, I have worked on these machines many times, air and water cooled. Do you have a code chart on a panel to tell you what the 2 beeps are on the control board? Do you have the original troubleshooting manual? This would be of a lot of help. This KM900 is a good size ice machine. I would pick up a gallon of nickle safe ice machine cleaner at a refrigeration parts house, read the instructions and run the machine through the cleaning cycle again. Hand clean everything you can get to again, this is the biggest problem I find on water cooled units. The nickel safe is an excellent cleaner made for this problem. Do you have a water softener for the inlet water on this machine? If not I would recommend having one installed. This will cut down on a lot of problems you will have in the future. Try this and get back to me and let me know. In the mean time I will research this ice machine to see what I can come up with.
