A couple things to look at: There is a water float switch that initiates the harvest cycle. When the level of water in the sump gets down to a certain point, assuming that the missing water from the sump is now ice, a float switch makes. If you pull the front cover off, you'll see it right there in front, to the right of the water pump. It's round and white with a rubber bottom that connects to the sump. Shut the unit off and drain the sump, there should be either a threaded plug in the bottom or a u-shaped hose that connects to one end of the pump. (depending how old it is) if it has the u-shaped hose, just pull it off and the sump will drain into the bin. Remove the float switch and clean it, make sure it works by using your ohm meter. if it doesn't, replace it. it's cheap. The second thing to look at is the evaporator. make sure the stainless steel panels aren't falling off of the tubing behind it. I've seen this happen alot. the only way to fix that is to replace the evaporator. One more thing you should do while the sump is drained. To the left of the water pump should be a hose conection that is in the shape of a triangle with 3 screws. It's a check vale. Take the hose off of it and remove the screws. pull out the spring and stetch it out a couple of inches and put everything back together. This will ensure that your not losing water from your sump through that valve, during ice making, causing premature harvest and very small ice cubes.
One more thing to look at, check your head pressure during harvest. If it's R-404a refrigerant, you should be up between 80 and 90 psi. It will start out low and slowly go up. Good luck, Matt
