The short answer first
On a Klarstein refrigerator, no ice usually means the machine correctly believing the bin is full. The assembly itself fails far less often than the things feeding it, so the checks below start at the supply and finish at the module.
Symptoms, including the misleading ones
- Ice has a stale taste or smell — A filter past its life, or old ice sitting in the bin for months, rather than a production fault.
- Cubes are hollow, small or misshapen — Partial fills point at restricted water rather than a dead assembly — the mould is filling, just not enough.
- Water pools under the icemaker or in the bin — An overfill or a mis-aimed fill tube, which is a supply fault rather than a production one.
- NEAR MISS — water is leaking onto the floor from the icemaker area — Water on the floor is a leak page. Deal with the leak first; it usually also explains the ice.
What goes wrong here, in order
- The machine correctly believing the bin is full — A machine stopped this way is working perfectly and producing nothing, which is exactly the case that gets a healthy assembly replaced. It heads the list because it is the failure this class shows first, and the one an owner can settle without opening anything. This class is light, portable and thinly insulated, and every one of those facts pushes the environmental causes to the top of the order.
- Water supply shut off, kinked or frozen at the fill tube — A line pinched by the cabinet being pushed back against it is one of the most common causes of this complaint, and it appears at exactly the moment nobody associates with the icemaker: after a clean behind the fridge. Next in order: it explains a smaller share of these faults but is quick to confirm once the first is clean.
- A freezer running warm, so the mould never releases — Harvesting ice is a temperature-triggered event, not a timed one, so a freezer running a few degrees warm will slow or stop ice production while keeping food perfectly frozen. Third, and only worth attention once the two above are clean.
- Icemaker module, mould heater or fill valve failure — Of those three the valve is the likeliest, because it is the only one that works against line pressure and the only one exposed to whatever the water carries. It ranks last on the evidence rather than on its importance: when it is the answer, it is unmistakable.
Work through it in this order
- Look at the bail arm or switch and confirm the icemaker is actually switched on — The arm should rest down on the ice, not sit up against its stop. Do this first: it settles the likeliest cause before any tool comes out.
- Look at the fill tube where it enters the freezer for a plug of ice — A visible lump of ice at the tube outlet answers the question without any tool. Second in order, and only worth doing once the first has come back clean.
- Put a thermometer between packages in the freezer and read it after some hours — A freezer holds food safely at 0 degrees Fahrenheit or below; ice production suffers above that long before food does. Third, and only if the two above found nothing.
The steps, with tools and times
- Lower the bail arm or switch the icemaker back on and wait several hours — A first harvest after a restart can take a surprisingly long time; judge it the next day.
About 10 min
- Pull the cabinet out and check the supply line is open and not pinched — Straighten the line so it has a loose loop behind the cabinet before pushing it back.
Tools: torchAbout 25 min
- Clear the freezer vents and repack so air can move around the load — Packing against the rear vents starves the whole compartment, icemaker included.
About 20 min
- STOP here and write down what each check showed — A technician arriving with the cheap causes already eliminated spends the visit fixing rather than repeating your work.
The safety part
Safety
Switch the power off at the plug or the breaker before anything comes apart, and leave it off while you work. A refrigerator carries a capacitor that holds a charge after the power is off, and the door switch is there to cut the fan for a reason — never defeat it to keep the light or the fan running while your hands are inside.
The line between a fix and a call
Call when water reaches the cabinet, the filter is new, the freezer is at temperature and the arm is down, and there is still no ice. That combination points at the valve or the module, and both are parts jobs.

A note on scope: this page treats Klarstein refrigerators as one class. A page written for your specific family or model line will carry what this one deliberately leaves out — component locations, fastener sizes and the disassembly order — and it takes precedence over this page for your unit.
