Direct answer: When a Bosch refrigerator is not making ice, the usual causes are the ice maker being turned off, the freezer running a little too warm, a jammed ice mold or bin area, or a restricted water supply to the refrigerator ice maker.
Most likely: Start with the simple stuff: confirm the ice maker is actually on, the freezer is cold enough to hold hard ice, and there is no clumped ice blocking the ejector or bin area.
Ice makers are picky. If the freezer is only slightly warm, the water filter is restricted, or cubes have jammed the mechanism, ice production can stop without much warning. Reality check: a refrigerator can still seem cold and still be too warm for steady ice production. Common wrong move: replacing the whole refrigerator ice maker before checking whether water is even reaching it.
Don’t start with: Don’t start by ordering a refrigerator control board or taking apart sealed cooling components. Most no-ice calls turn out to be settings, temperature, airflow, or a fill problem.
The refrigerator runs normally, but the ice bin stays empty for a day or more.
Start here: Check that the ice maker is switched on, the bin is seated correctly, and the freezer is cold enough to keep food fully frozen.
You may hear a brief hum or cycle sound, but the mold stays dry.
Start here: Look for a kinked supply line, a recently changed or overdue refrigerator water filter, or a frozen refrigerator ice maker fill tube.
You get a few cubes, then long gaps, especially after the door has been opened a lot.
Start here: Check freezer temperature, door sealing, and whether packages are blocking freezer airflow around the ice maker area.
You see fused cubes, a stuck rake, or cubes wedged where they should drop into the bin.
Start here: Empty the bin, clear loose jams, and make sure melting and refreezing from warm air is not the real cause.
This is common after cleaning, loading groceries, or removing the bin. The refrigerator may cool fine but never call for a harvest.
Quick check: Confirm the ice maker setting is on and the ice bin is fully installed without rubbing or sitting crooked.
Ice makers usually stop or slow down before the rest of the refrigerator feels obviously warm. Soft ice cream and wet-looking frost are good clues.
Quick check: Check whether frozen food is truly hard and whether the door has been left ajar or the gasket is leaking.
A clogged refrigerator water filter, kinked line, or low household water flow can leave the mold dry or only partly filled.
Quick check: If the refrigerator water dispenser is slow too, the problem is likely in the refrigerator water supply path rather than the ice maker motor itself.
If the freezer is cold, the setting is on, and water supply is present, the fill path or the ice maker itself becomes the stronger suspect.
Quick check: Look for ice packed in the fill tube above the mold, or a mold that never fills or never ejects even after a full day.
A lot of no-ice complaints are really a setting issue or a freezer that is just warm enough to stop ice production.
Next move: If ice starts coming back within the next day, the problem was likely settings, bin position, or freezer temperature drift. If the freezer is clearly cold and the ice maker is on but still no ice, move to the fill and blockage checks.
What to conclude: This separates a simple operating issue from a real water-fill or ice-maker fault.
A jam in the mold, rake, or bin area can stop production even when the ice maker itself still has power.
Next move: If the ice maker resumes after the jam is cleared, the main issue was blockage, often caused by warm air getting in or cubes partially melting. If the mold stays dry or the mechanism never returns to normal, keep going and check the water side.
What to conclude: A jam points to either a one-time blockage or a temperature and sealing problem that let cubes melt and refreeze.
If water cannot reach the mold, the ice maker cannot produce cubes no matter how good the motor is.
Next move: If dispenser flow improves and ice returns, the restriction was in the refrigerator water supply path. If water flow to the refrigerator seems normal but the ice maker still stays dry, inspect the fill tube and ice maker area next.
A frozen fill tube or a dry mold gives you a strong clue about whether the problem is upstream water delivery or the ice maker assembly itself.
Next move: If a small ice plug clears and the next fill is normal, you likely had a temporary freeze-up in the fill path. If the mold stays dry despite good water supply, or the mold holds cubes that never harvest, the refrigerator ice maker assembly is the stronger repair path.
By this point you should know whether you have a simple supply restriction, a repeat fill-tube freeze issue, or an ice maker that is not cycling correctly.
A good result: If the right part was matched to the symptoms, you should see normal fill and fresh cubes after the refrigerator has had time to cycle.
If not: If a new filter or ice maker does not change anything, the problem is likely outside the easy DIY path, such as repeated fill freezing, airflow trouble, or a control issue that needs model-specific testing.
What to conclude: This is where you stop guess-buying and make one supported repair or move to the cooling problem that is actually causing the no-ice complaint.

If the water dispenser still works, the refrigerator has at least some water supply. That usually narrows the problem to a jammed ice maker, a frozen fill tube, a warm freezer, or a refrigerator ice maker assembly that is not cycling correctly.
The freezer needs to be solidly cold, not just cool. If food is a little soft, ice cream is easy to scoop, or you see wet frost, the ice maker may stop before the rest of the refrigerator seems obviously warm.
Yes. A restricted refrigerator water filter can slow or stop water flow enough that the ice maker mold never fills properly. If dispenser flow is weak too, the filter or supply path is a strong suspect.
A dry mold usually means water is not reaching the refrigerator ice maker. Check the water filter, supply line, dispenser flow, and the fill tube for freezing before replacing the ice maker.
Not first. Replace the refrigerator ice maker assembly only after you know the freezer is cold enough, the ice maker is turned on, the bin is seated right, and water can actually reach the fill path.
