The short answer
On a freestanding Blomberg refrigerator, excess frost is far more common than a failed ice maker, because many of these cabinets are sold without any plumbing at all. Work out first whether your cabinet has a water connection: if it does not, every ice complaint on it is a frost and sealing complaint.
What you are seeing
- Frost building at the back of the freezer drawer nearest the door
- Heavy frost building on the back wall of the freezer section
- Frost forming on the food packages themselves
- An ice maker that produces nothing at all
- An ice maker producing hollow, small or partial cubes
- Ice that smells or tastes of the cabinet contents
- Body: The two faults look nothing alike: Frost building at the back of the freezer drawer nearest the door. Heavy frost building on the back wall of the freezer section. Frost forming on the food packages themselves. An ice maker that produces nothing at all. An ice maker producing hollow, small or partial cubes. Ice that smells or tastes of the cabinet contents.
Causes, most likely first
- A cabinet with no water connection at all — Why: many freestanding models in this range are not plumbed, so an "ice maker not working" complaint is often a cabinet that never had one; check the specification before looking for a valve.
- A freezer drawer not pushed fully home — Why: a drawer standing proud holds the outer door off its seal, and on a bottom-freezer cabinet that is the single most common source of frost.
- A door left ajar or a gasket not sealing — Why: warm moist air entering the cabinet condenses and freezes on the coldest surface, which is behind almost every excess-frost complaint.
- Overpacked shelves blocking the airflow — Why: air that cannot circulate drops its moisture in one place, which is why frost appears on packages rather than being carried away.
- The ice maker arm or switch left off — Why: a lever knocked while loading the freezer stops production silently, and it is the first thing to check before touching any plumbing.
- A closed or restricted water valve — Why: the supply valve behind the cabinet is often closed during installation or later work, and the ice maker then makes nothing at all.
- Body: Ranked across both halves of the complaint: First, A cabinet with no water connection at all: many freestanding models in this range are not plumbed, so an "ice maker not working" complaint is often a cabinet that never had one; check the specification before looking for a valve. Second, A freezer drawer not pushed fully home: a drawer standing proud holds the outer door off its seal, and on a bottom-freezer cabinet that is the single most common source of frost. Third, A door left ajar or a gasket not sealing: warm moist air entering the cabinet condenses and freezes on the coldest surface, which is behind almost every excess-frost complaint. Fourth, Overpacked shelves blocking the airflow: air that cannot circulate drops its moisture in one place, which is why frost appears on packages rather than being carried away. Fifth, The ice maker arm or switch left off: a lever knocked while loading the freezer stops production silently, and it is the first thing to check before touching any plumbing. Sixth, A closed or restricted water valve: the supply valve behind the cabinet is often closed during installation or later work, and the ice maker then makes nothing at all.
What to check, in order
- confirm whether the cabinet is plumbed at all before looking for a water valve, because an unplumbed model has no ice maker to fault.
- decide whether you have too much frost or too little ice, because nothing below applies to both.
- for frost, check the door seal and the packing, since air ingress explains nearly all of it.
- for an ice maker, check the arm or switch position, then the water valve behind the cabinet.
- Body: Split the fault, then follow one branch only: First, confirm whether the cabinet is plumbed at all before looking for a water valve, because an unplumbed model has no ice maker to fault. Second, decide whether you have too much frost or too little ice, because nothing below applies to both. Third, for frost, check the door seal and the packing, since air ingress explains nearly all of it. Fourth, for an ice maker, check the arm or switch position, then the water valve behind the cabinet.
Checks you can do yourself
- Push each freezer drawer fully home and check the outer door then closes without resistance — Tools: none — Time estimate: a few minutes
- Close the door on a paper strip at several points and note where it slides out freely — Tools: paper strip — Time estimate: a few minutes
- Rearrange the shelves so nothing blocks the vents and nothing holds the door open — Tools: none — Time estimate: a few minutes
- If an ice maker is fitted, check its arm or switch is in the on position — Tools: torch — Time estimate: a few minutes
- Check the water valve behind the cabinet is fully open and the supply line is not kinked — Tools: torch — Time estimate: a few minutes
- Body: Work one branch at a time: Push each freezer drawer fully home and check the outer door then closes without resistance (none; a few minutes). Close the door on a paper strip at several points and note where it slides out freely (paper strip; a few minutes). Rearrange the shelves so nothing blocks the vents and nothing holds the door open (none; a few minutes). If an ice maker is fitted, check its arm or switch is in the on position (torch; a few minutes). Check the water valve behind the cabinet is fully open and the supply line is not kinked (torch; a few minutes).
Safety first
Safety
A freezer holds food safely at 0 °F (−18 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip ice off an evaporator with a knife or a screwdriver: the tubing carries a flammable hydrocarbon refrigerant and punctures easily. Never use a heat gun or a hairdryer near the plastic liner. unplug-before-service freezer-0f
When to stop and call a technician
These need a technician: Frost returns on a cabinet whose drawers close properly and whose seal passes the paper test. Frost returns within days of a complete manual defrost. The ice maker does nothing with the arm on and the water valve open. Cubes are consistently hollow after the supply has been checked.

What this page does not cover
This page is generalized across every refrigerator sold under the Blomberg name: it separates neither the counter-depth freestanding cabinets from the deeper ones and the bottom-freezer layouts from the single-door ones, and it names no individual model. Where a family- or model-specific page exists it is linked here and it outranks this one for that machine; at present no page beneath this one narrows to a single family, so treat the ranking above as the brand-level pattern rather than a reading of your serial plate. The same cabinets are also listed under the alternate capitalisation and under the common misspelling Bloomberg; those pages cover the built-in installation and the deeper diagnostic tier, and they are linked here. For the other faults that turn up on this machine, start from Common BLOMBERG Refrigerator Problems.
