The short answer
Ice faults on the Caf QC family fall into three buckets: no water in, water in but no harvest, and ice made but jammed on the way out. With six model tags in the matrix below, this family covers several passes of the same platform, and a cause that is a running change on one group can be absent on another. Work out which bucket you are in before touching anything, because each one has a different first check and they do not overlap.
What you can observe on these models
- Water pools under the bin and refreezes — Overfill or a misaligned fill tube. It ends as a sheet of ice under the bin and a jammed auger.
- The bin is empty and the mould is dry — No water is arriving. Everything upstream — arm position, shutoff, filter, fill tube, valve — comes before any thought of the module.
- Cubes are small, hollow or crescent-shaped — Water is arriving but not enough of it. That is flow: a restricted filter, a partly closed shutoff or low supply pressure.
- The mould holds water that never releases — The fill worked and the harvest did not. Look at freezer temperature and at the module, in that order.
- NEAR MISS — water leaking from the dispenser front — That is a water-leak fault rather than a production fault, and it belongs on the leak page.
Causes, most likely first on this family
- Bail arm raised or the ice maker switched off — First because it costs one look and because a bin that was pushed back hard will lift the arm on its own.
- Filter past its life or an aftermarket cartridge that does not seat — Second, and the cause most likely when production changed right after a filter change.
- Frozen fill tube or an overfilled mould — Third: warm air from a dryer at a distance clears it in minutes, which makes it worth proving before anything is ordered.
- Freezer running warmer than the harvest point — Fourth, and the check that turns an ice complaint into a cooling one.
- Inlet valve or module failure — Last: these are the parts, and parts come after the free checks on every one of these models.
Check in this order, and why
- Empty the bin completely and look underneath — A sheet of ice under the bin jams the auger and stops delivery while production continues normally.
- Confirm water reaches the mould on a forced fill — Water arriving and then sitting unfrozen moves the whole fault to temperature rather than supply.
- Check the fill tube alignment — A tube nudged out of line overfills the mould edge and builds the plug that stops the next cycle.
- Compare cube size over a full day — Hollow cubes that stay hollow confirm restricted flow; normal cubes that stop confirm the harvest side.
Before you open anything
Safety
Power off at the plug or the breaker before any panel comes off; a capacitor can hold a charge after the power is off. Close the water shutoff before disturbing the supply line or the filter head, and have a towel ready — the line stays under pressure until it is bled. Never run the ice maker with a hand near the ejector.

When to call a technician
Clearing ice, reseating a bin, changing a cartridge and opening a shutoff are yours. Call once a part has to be condemned — valve, module, thermostat or auger motor — because each of those needs the tag from the interior label and a test rather than a guess. Call urgently if you find water pooled under the cabinet rather than inside it.
