A lit NO WATER lamp means the maker's own answer is low water supply, and the chain from the shut-off through the filter and the line to the reservoir is where the problem is. Then check the shut-off itself — behind or under a built-in machine, and closed during other work far more often than anybody admits. ### Almost always water, not cold An ice machine that has stopped is a water problem far more often than a refrigeration one, and the chain is short: a shut-off, a filter, a line, a valve, a reservoir. Three of those five cost nothing to check and one of them is the answer most of the time. ### The one that ends machines here Scale. U-Line signals for a cleaning cycle after six cumulative months of ice making and keeps signalling until it gets one, and in South Florida six months is optimistic. Scale narrows every water path in the machine at once, which is why a machine that has never been descaled fails in several places in the same season. The water supply, anywhere along it Shut-off, filter, line, inlet valve. These machines mind flow rather than pressure, so a filter at the end of its life starves one slowly enough that nothing looks wrong. The thing that ends ice machines in South Florida. The maker signals for a cleaning cycle every six cumulative months and keeps signalling until it gets one; six months is optimistic on this water. The bin arm or the fill limit A machine told it is full will stop while being perfectly healthy. On the crescent makers this is the single most common false alarm. Ice frozen and never released. On a crescent maker that is the mold heater; on a clear ice machine it is the hot gas valve; on a nugget machine it is the auger. The refrigeration itself Last, because it is least likely. A machine that is not cold is diagnosed like a refrigerator: sensors, airflow, then the sealed system. Look at the lamps A lit NO WATER lamp is the maker's own answer: low water supply. Three lamps flickering twice in turn is a cleaning request, not a failure. Find the shut-off and check it is open Behind or under the machine. It gets closed during other work more often than anybody admits and it costs nothing to check. Check the bin arm Resting up means the machine has been told the bin is full and it will sit there indefinitely being perfectly healthy. Note when the filter was last changed A filter does not fail, it slows. A machine making less ice each month rather than stopping is usually describing a filter. Water in, harvest, water out — in that order What it usually means Stopped completely Making less and less over weeks Freezing water but never dropping it Find out whether water is arriving Look at the machine's lamps first.

That is usually flow rather than a failure: a filter at the end of its life, a partly closed valve, or scale. A machine that produces less each month is describing a restriction that is getting worse. ### The ice tastes wrong. Filter first, then the cleaning cycle with the maker's own cleaner. A reservoir that has not been cleaned in a year will flavor everything that passes through it. --- **[Read full article: Ice maker not making ice](https://ulinemiami.support/symptoms/ice-maker-not-making-ice/)**
