    When the Machine goes into harvest I get pressures that correspond to the book (170Head/80-85Suction) however, the ice will come free on the left hand side of the evaporator, and then melt out of the right side until it finally drops(it eventually locks out on long harvest). I used sanitizer but it made no difference. One thing I noticed was the discharge line would start out at 160 plus degrees, and then would be room temperature, but the pressure was still 80 to 85 lbs. I find it hard to be under charged being my pressures are so close, but could this be the case?

    On a side note, it is always the right hand side of the evaporator that gets "stuck"

    Sounds like a classic case of evaporator grid separation. Shine a flashlight in the ice free grid where it sticks. I think you will find the grid separating from the evap plate. If so throw the machine away and buy a new one.
    A Diamond is just a piece of coal, that made good under pressure!

    make sure ice mold is not bent or scratched. let plate dry and see what it looks like. sanitizer will not remove mineral build up.

    Ive heard of guys using the wrong cleaner and having some weird problems, but on one side, could it be a restriction, just guessing

    It is a half dice machine, and some of the cross sections of the grid do move slightly(or do stick out of the plate slightly). Also, at one point in the grid it looks like someone grinded the cross section or it somehow got burnt or damaged, manager says no one torched it. I used Nu-Calgons Nickel-Safe Ice Machine Cleaner which meets Manitowoc’s specification #GES-6 and a soft brush. I had a feeling the machine was shot.

    On a side note, the machine is from 96. At what point do you tell your customer it has outlived its useful life and is not worth repairing?

    Thanks

    if the grid is seperated you are at the point of telling the customer it has outlived its usefulness

    Manitowoc Ice machine have an average commercial life of 10 years. Yours looks like it is 10 years old. Time for a new one. For info call the factory tech surport.

    I'm betting you are correct on this. I've seen this a LOT.

    sounds like a bad evaporator plate

    I agree w/ other posts sounds like you need a new evaporator plate. They are easy to replace. I have always wanted to try and replace the damaged grids just for fun, but have not attempted it yet. curious if any one out there has done this successfully?

    To attempt to repair grids would be nothing more than a temporary fix.
