    Manitowoc ice harvesting, just not breaking up

    Had a buddy shoot me a text regarding his undercounter ice machine..Manitowoc. He came into the coffee shop one day this week to open up and said that his ice machine (UD-0140A) was making the ice, however when it would fall off of the cell, it’s no longer breaking apart into individual pieces but staying together as one full sheet. The water is fully covering the cell, the ice thickness probe hasn’t been moved from its factory position and harvest probe was inspected and no junk was on the probe itself (his words). What could cause the ice to stay together and not fall apart? I haven’t been by to look at it but plan to one day this week if he can’t get someone else out, so sorry for the lack of information. Machine is only a year old.

    —Water regulating valve allowing water by during harvest which would allow the ice to stick and not break apart fully when harvested?

    —Was thinking maybe hot gas not warm enough to fully break apart, but then how would it detach from the cell completely if not?

    —Could something as simple as running cleaner through the machine work? I was reading that even a small amount of dirt/bacteria on nickel plating won’t allow for complete removal, but I would assume that meant sticking to the cells and not falling at all.

    Just looking for someone that may have experienced a similar situation and what you remember finding or checking. I know a lot probably needs to be checked in person but any info would be helpful. Thanks

    It wont fall apart because the ice is too thick.

    Maybe the ice thickness probe needs to be adjusted to a thinner sheet or needs to be replaced.

    If it's not shutting down

    First check level. Too much water makes too much ice.
    Second dirty condenser causing slush not making a full cell of ice so the bridge is thicker and cubes are smaller.
