    Scotsman Prodigy codes

    A customer's ice machine is acting out again. Prodigy series air cooled unit mounted on a soda dispenser/ice bin. The last two errors are code 2, max harvest and code 8, short freeze. The tech literature is not specific as to what triggers these codes Any suggestions?

    I have cleaned the machine quarterly for the last 2 years, most recently 3 weeks ago. The only other issues it has had were bun door switch and water inlet valve, both over a year ago.

    Cool

    check the cube size control if ice too thin will cause both error codes

    Had one doing this last week. Harvest assist solenoid was bad. It was not pushing the ice sheet off the evap during harvest. The ice sheet would not fall on its own and would give the max harvest error. Then the unit would try and freeze another cycle with the previous ice still on the grid touching the ice thickness probe setting it off in to a short freeze error.
    We do it nice cause we do it twice!

    This one turned out to be dirty sensors. Didn't realize that the metal separates form the plastic on both the water level sensor and ice thickness sensor. You have to get all of the pieces apart ans clean between them. That is what we did Friday, and if it didn't fix the problem, new sensors will be ordered Monday.

    #2 is max harvest and 8 is short freeze. This is a HUGE problem with prodigy.the problem is the sheet of ice is splitting in the middle occasionally. This will cause the bottom to fall off and restart the freeze leaving the top on to either touch the cube size control and cause short freeze #8 or ice up causing unit to not harvest properly next time and giving you #2.

    Now Scotsman fix for this used to be "just make the cube size bigger" well the cube size is fine and bigger is not better on a dispenser. Now they have a hinged curtain kit if you need the part number let me know.

    Even worth the hinged curtain we still get this error occasionally. I hate this machine. But I will have the pleasure of working on them every day.

    Thats what i was about to say. I had a C1030 do the same thing. It was the ice thickness sensor and Scotsman had me replace the curtain with the articulated one while i was there.

    Also, if you guys ever run into the curtain sticking open, look where the plastic screws to the top of the evap. there are two screws that hold it down and sometimes they loosen up. This causes the curtain to swing a certain way and the one i was working caught the globs of silicone they use to seal the tank. Next thing you know 1 batch get made and the machine indicates bin full.

    That sounds like the cubes are too thin and the harvest assist solenoid is splitting it. Check the ice thickness sensor adjustment.

    The cubesheet is probably too thin, but I seriously doubt the harvest assist solenoid is what is breaking the sheet.

    I have not really seen this problem very often. The only times I have seen a sheet break it has been because the bridge thickness was far too thin. A few times I have seen a sheet fracture during the last few minutes of freeze and leave the evap as two separate pieces, but this is not common.

    ive actually seen this plenty of times. the harvest assist pushes the center out and splits the sheet in two because yes, the bridge is too thin. This can come from someone who "knows ice machines" decides to screw with the factory setting. Also if the evap gets all scummed up it will do this too.

    Out of curiosity, if its not the harvest assist breaking it, then what is splitting it in your opinion?

    The harvest assist may very well be splitting it, but only if the sheet bridge is really thin. In that case, the harvest assist isn't the problem obviously.

    If the sheet is splitting with a normal bridge, it might be fracturing during freeze and you just aren't noticing it until harvest. I guess is is POSSIBLE for the solenoid to break a normal thickness sheet, but I have never noticed it. Is the solenoid powered from the very beginning of harvest? If so, I wouldn't see it breaking it. If it is energized later in harvest, I could see the sheet sliding a little but off the grid so there is a space between the solenoid push rod and ice so that when the solenoid is finally energized it is allowed to move and slam into the back of the ice sheet.
