Bosch Refrigerator: No Ice
The fault was dealt with once and has returned, which changes the ranking. On a Bosch refrigerator that has stopped making ice, the finding that comes up most often is a counter-depth or built-in installation starving the machine of air, followed by the feeler arm or the on-off switch left off. An ice maker is a small machine with a water supply, a freezing cycle and an ejection mechanism, and the fault is nearly always in the water supply or in the freezer temperature rather than in the ice maker itself. That first step is yours to make and it costs nothing; the causes below it stop being owner work quickly.
What you are seeing
- an empty ice bin with the ice maker switched on
- ice cubes that are hollow, small or misshapen
- a solid block of ice fused in the bin
- Not this fault: If neither water nor ice is available, the supply is the fault rather than the ice maker
- Body: What you are seeing: an empty ice bin with the ice maker switched on; ice cubes that are hollow, small or misshapen; a solid block of ice fused in the bin. If neither water nor ice is available, the supply is the fault rather than the ice maker.
Ranked causes on a Bosch refrigerator
- A counter-depth or built-in installation starving the machine of air — Tag: install — Why: It leads here because this is a machine fitted flush into cabinetry, where the air path in, which no other badge presents. — Presentation:
- The feeler arm or the on-off switch left off — Tag: usage — Why: It sits at this position because the causes above it are more common, cheaper to check, or both. — Presentation: An ice maker in perfect condition with its arm raised or its switch off.
- A freezer that is not cold enough to complete a freeze cycle — Tag: sensor — Why: It ranks high here because Bosch supervises with sensors and a base-pan float, so the machine often stops itself as designed. — Presentation: Hollow or small cubes, or very slow production, with everything else working.
- A frozen or closed water supply line — Tag: water-inlet — Why: It sits at this position because the causes above it are more common, cheaper to check, or both. — Presentation: No water arriving at all, often after the household supply was turned off or the machine was moved.
- Body: Ranked for a Bosch refrigerator — the order is the point. First: a counter-depth or built-in installation starving the machine of air. It leads here because this is a machine fitted flush into cabinetry, where the air path in, which no other badge presents. Second: the feeler arm or the on-off switch left off. It sits at this position because the causes above it are more common, cheaper to check, or both. Third: a freezer that is not cold enough to complete a freeze cycle. It ranks high here because Bosch supervises with sensors and a base-pan float, so the machine often stops itself as designed. Fourth: a frozen or closed water supply line. It sits at this position because the causes above it are more common, cheaper to check, or both.
What to check, in order
- A counter-depth or built-in installation starving the machine of air — Reason: It is first because it exists on this platform and not on the others, so nothing else you check can rule it out for you.
- The feeler arm or the on-off switch left off — Reason: It comes second because a counter-depth or built-in installation starving the machine of air either accounts for the fault or, once ruled out, leaves this as the next thing the evidence supports.
- A freezer that is not cold enough to complete a freeze cycle — Reason: It comes third because the feeler arm or the on-off switch left off either accounts for the fault or, once ruled out, leaves this as the next thing the evidence supports.
- Body: The order below is built for a repeat fault: what a first repair leaves behind comes first. There is a standing rule on this platform: clear and inspect the manual filter before anything else, and check whether the base-pan float has tripped — Bosch will shut a machine down.

Checks you can make safely
- Check that the enclosure gives the machine the clearance its installation instructions ask for, and that nothing is stored against the grille or behind the cabinet — Tools: a torch and a tape — Time: a quarter of an hour — Targets: A counter-depth or built-in installation starving the machine of air
- Lower the feeler arm or switch the ice maker on, and confirm the bin is seated fully home so the arm can drop — Tools: nothing — Time: a few minutes — Targets: The feeler arm or the on-off switch left off
- Put a thermometer in the freezer overnight and compare it with the safe storage temperature — Tools: a freezer thermometer — Time: a few minutes, then overnight — Targets: A freezer that is not cold enough to complete a freeze cycle
- Body: These checks aim at what a first repair leaves untouched. Step one: Check that the enclosure gives the machine the clearance its installation instructions ask for, and that nothing is stored against the grille or behind the cabinet. Tools: a torch and a tape. Allow a quarter of an hour. Step two: Lower the feeler arm or switch the ice maker on, and confirm the bin is seated fully home so the arm can drop. Tools: nothing. Allow a few minutes. Step three: Put a thermometer in the freezer overnight and compare it with the safe storage temperature. Tools: a freezer thermometer. Allow a few minutes, then overnight. Stop at the first step that would put a meter on live terminals or open a sealed system — that is where owner work ends.
Before you touch anything
Safety
Unplug the machine before reaching into an ice maker — the ejector can cycle at any time and the heater in the mould is live. Never use a knife or a screwdriver to chip ice out of a mould or a chute; you will puncture something that is expensive to replace. One thing to keep in mind on this platform: condensation drying rather than a heated-dry element on dishwashers — that changes where your hands go. electrical water Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.
When to stop and call
Call a technician if any of these is true: the supply is open, the filter is new and the fill tube is clear with no fill happening; the ice maker never cycles at all; the freezer will not hold a temperature cold enough to freeze a mould. Above that line the next measurement is on live terminals or inside a sealed system. the supply is open, the filter is new and the fill tube is clear with no fill happening the ice maker never cycles at all the freezer will not hold a temperature cold enough to freeze a mould
