A dedicated ice machine is a small luxury that is very noticeable when it stops. Whether it is a Scotsman nugget maker at the bar, a Sub-Zero built-in ice maker, or an undercounter gourmet unit, the mechanics are more involved than the ice cube tray in a standard freezer. Mineral-rich mountain water also puts these machines under extra strain. We diagnose the fill, harvest, and cooling stages and repair the specific fault.
What We Fix
- Ice makers producing no ice or very little
- Water inlet valves and frozen fill tubes
- Harvest mechanisms that will not release ice
- Thermistors and temperature-control faults
- Cloudy, small, or misshapen ice
- Scale buildup and clogged water lines
- Drain pumps and water pooling
- Control boards, sensors, and error codes
Common Problems We See
The most frequent call is simply no ice, followed by low production and ice that comes out cloudy or undersized. A machine that leaks water or forms a block of ice in the bin instead of individual cubes is also common. Because the valley's water carries a lot of minerals, scale is behind a surprising number of these complaints, and regular descaling prevents many of them.
Typical Causes
No ice usually traces to a stuck water inlet valve, a fill tube frozen shut, or a harvest cycle that has failed to release. Low or cloudy production is most often scale coating the evaporator and water path, or a filter well past its life. A machine that will not harvest can have a thermistor giving a bad reading, and pooling water points to a drain pump or a blocked drain line. We test the water supply first, then work through the fill, freeze, and harvest stages so the repair addresses the true fault.
Brands We Service
We repair ice makers from Scotsman, Sub-Zero, True Residential, Thermador, Viking, and KitchenAid.
Ice Maker Error and Fault Reference
| Symptom | Likely Cause | What We Do |
|---|---|---|
| No ice at all | Stuck inlet valve or frozen fill tube | Test valve, thaw and clear fill path |
| Low or cloudy ice | Scale buildup or old filter | Descale, replace filter, flush water path |
| Will not harvest | Thermistor or harvest mechanism fault | Test sensor, repair harvest system |
| Water pooling | Drain pump or blocked drain | Clear drain, test and replace pump |
| Ice clumps in bin | Bin thermostat or airflow issue | Test bin control, verify airflow |
Out of Ice Before a Gathering?
Book a diagnosis and we will get it producing again. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
