The short answer
On the Blomberg G refrigerators specifically, this fault sits one level below the brand-generic answer: the models in this family share a layout, and that layout changes which check comes first. Ice production is a supply chain with four links: water arriving, water freezing, ice harvesting, ice storing. Work out which link broke and the repair is usually obvious. Work the chain in order. Diagnosing the mechanism before confirming the supply is how people replace working parts.
What you observe on these models
- Water appears in the bin instead of ice — Fill is arriving and the mould is not getting cold enough to set it before the next stage.
- Ice production stops whenever the freezer is full — Air cannot circulate to the mould, so the cold it needs to reach its trigger never arrives.
- Cubes are smaller and hollower than they used to be — Partial fill, which points at restricted flow rather than at no flow.
- NEAR MISS — the ice tastes or smells wrong but production is normal — That is a filter and storage question rather than a production failure.
Causes, most likely first on this family
- Fill tube frozen shut — Third: a slow drip at the end of a fill leaves a plug of ice in the tube, and each subsequent fill adds to it until nothing gets through.
- Water filter past its service life and restricting flow — Second on likelihood, and the easiest of all these causes to test — bypass or replace the cartridge and watch the next cycle.
- Water supply shut off, kinked, or the saddle valve closed — First, because it is the one cause that produces a completely dry mould with an ice maker that is otherwise in perfect health, and it is the one most often discovered behind a recently moved cabinet.
- The departure from the page above this one — The generic article lists these causes in frequency order across every model the brand sells. Here the ordering also accounts for how this family is built — which panel comes off first, and which component is behind it — and that pushes the accessible causes up.
Check in this order, and why
- Feel whether the bin is seated square in its rails — A bin sitting proud holds the arm up, and the machine then behaves exactly as it would with the ice maker switched off.
- Look at the shut-off arm or the control switch — Raised arm, or switch off, and the ice maker is doing exactly what it was told. Ten seconds, no tools, and it ends a surprising number of these calls.
- Note the size and shape of recent cubes — Small, hollow or partial cubes are the signature of restricted flow, which points at the filter rather than at the valve.
- Why this order suits these models — The sequence above is chosen for this family's construction: each step is picked to eliminate as much as possible before anything has to come apart, so the checks that need no panel removed are done first and the ones that do are left until they are the only possibility remaining.

Safety
Take the power off at the wall and leave it off for the whole job. Ice comes off with warm water and a plastic scraper and with nothing sharper; a punctured evaporator line ends the appliance on the spot rather than extending the repair.
When to call a technician
Stop at the first step that needs the cabinet powered with a panel off. That is not caution for its own sake: a running unit with its rear panel removed exposes a fan that does not care what is in front of it.
