The short answer
When ice production drops on the Caf QF family, the cause is more often upstream of the appliance than inside it — supply pressure, a shutoff that was never fully opened, or a filter past its life. The matrix below lists two model tags that differ only in their trailing revision characters, so a part that suits one usually suits its neighbours, and the tag still decides. Small or hollow cubes point at flow; no cubes at all with a wet mould points at harvest.
What you can observe on these models
- 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.
- Cubes have fused into a single block in the bin — Slow production plus repeated part-thaws welds the bin together. It is usually a symptom of a warm freezer, not of the ice maker.
- NEAR MISS — no ice and no cooling either — If the freezer is not holding temperature, the ice maker is a symptom. Work the cooling page first; the ice returns when the cold does.
Causes, most likely first on this family
- Freezer temperature above the harvest point — Ranked first here because the bin evidence points at temperature before it points at water.
- Supply flow — shutoff partly closed, filter restricted or a kinked line — Second: the line behind the unit gets crushed when a cabinet is pushed back into place, and the symptom is identical to a tired filter.
- Fill tube ice plug — Third, and the one to clear last among the water-side causes so it does not simply rebuild.
- Dispenser chute or auger jam — Fourth: ice is being made and cannot get out, which is a delivery fault masquerading as a production one.
- Module, ejector or inlet valve — Last because every cause above it is either free or a consumable.
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.

Safety
Unplug the refrigerator or switch off its breaker before reaching behind the ice maker or removing a panel — a capacitor can hold a charge after the power is off. Do not chip a frozen fill tube or a bin sheet with a screwdriver: the tube deforms and the evaporator tubing behind it punctures easily. Warm air at a distance is the only safe way to clear ice on the Caf QF family.

When to call a technician
On the Caf QF family the owner side covers everything upstream of the module: the arm, the shutoff, the filter, the line, the fill tube and the bin. Call when water reaches the mould, the freezer is at temperature, and it still will not harvest — that is a module or thermostat fault and it needs a meter to condemn honestly. Call sooner if the supply line is weeping at a fitting, since a slow drip behind a cabinet does damage long before anyone sees it.
