The answer first
On a Liebherr refrigerator an empty ice bin is usually a water-supply or a temperature problem rather than a failed ice maker. The first two checks below take minutes and need nothing but your eyes and a glass. Replacing the ice maker is the last resort on this list, not the first move.
What you are seeing
- The dispenser gives water but no ice, or neither — Water at the dispenser proves the supply reaches the appliance, which eliminates half the list in one go.
- The bin is empty and stays empty — No cubes at all after a full day, with the unit otherwise running normally.
- NEAR MISS — there is water under the unit as well as no ice — A leak with an ice fault usually means the supply line or the fill valve, and the water-leak page covers that path in detail.
What goes wrong here, in order
- The water supply to the appliance — A shut-off valve left part-closed, a kinked line behind the unit, or a connection that was never opened after an installation will starve the ice maker without any other symptom. The unit keeps trying to fill and keeps getting nothing. It heads the list here: the supply is the part that gets disturbed whenever the unit is moved, and it explains more of these than anything inside the cabinet. Liebherr builds fully integrated European refrigeration with tight cabinet clearances and long service intervals, which puts installation and ventilation ahead of component wear on the list of things that go wrong.
- A clogged or overdue water filter — A filter at the end of its life drops the flow to a trickle. The ice maker fills partly, freezes what it has, and produces small hollow cubes or nothing at all — while the dispenser slows at the same time, which is the tell. Second on this brand: it is quick to test at the dispenser and it explains the small-cube version of this fault exactly.
- The freezer is not cold enough to complete a cycle — An ice maker will not harvest until the mould reaches its release temperature. A freezer sitting a few degrees warm — because the door is opened constantly, the cabinet is overfull, or the seal is tired — makes ice slowly or not at all while the food inside still looks frozen. Third in order: it is a real cause but it usually announces itself in the food as well as in the ice.
- The ice maker is switched off or the arm is held up — Every ice maker has an off position — a wire arm, a lever, or a setting on the control. Loaded groceries push that arm up, a child presses the wrong button, and the unit obediently stops making ice with nothing whatsoever wrong. Fourth: it is worth a glance before anything else is opened up.
The order to check in
- Trace the water line from the wall valve to the back of the unit — Look for a valve that is not fully open and for a kink where the line is pinched against the wall — both are common after a unit has been pulled out and pushed back.
- Fill a glass at the dispenser and watch the flow — A thin or stuttering stream is a filter or pressure problem; a strong steady one clears the whole supply path in a single test.
- Check whether the freezer is at 0 °F (−18 °C) or below — A freezer holds food safely at 0 °F (−18 °C) or below, and an ice maker needs roughly that to complete a harvest. Warmer than that and the ice is a symptom, not the fault.
Steps you can take safely
- Open the shut-off valve fully and straighten the supply line — Pull the unit forward far enough to see the whole run of the line rather than the last few inches of it.

- Replace the water filter and run several glasses through to purge the air — Expect sputtering for the first few glasses after a change. Ice made in the first batch afterwards is usually discarded.

- STOP before pulling the ice maker assembly out — Removing it means disconnecting a harness and often working around a fill tube that has frozen. That is where the owner check ends.
The part that is not optional
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Turn the water off at the wall valve before disturbing any connection, and never thaw a frozen fill tube with a flame or a heat gun; warm water and patience do it without melting the plastic around it.
The line between a fix and a call
Call when the water path is clear, the freezer holds 0 °F (−18 °C) and the bin is still empty: at that point the fault is in the valve or the module, and both involve disconnecting water and power at the same time. Call sooner if you find water anywhere it should not be.

What is deliberately not here
Generalized information, written for the class rather than the model. Where a Liebherr family- or model-specific page exists beneath this one, that is the page to read for your unit. Deliberately absent here: service-manual steps, component part numbers and any specification that differs family to family.
