The short answer
Neither code in the Beko BBMB table carries the IM suffix that marks an ice-maker build, so this family has no plumbed ice maker at all. An ice complaint here is frost forming where it should not, and on a large bottom-mount the place it forms first is the bottom of the fresh-food compartment - directly below a tall door that has stopped sealing at its lower edge.
What you observe
- Frost concentrated at the bottom of the fresh-food compartment — Warm air entering under a racked door and freezing on the first cold surface it meets.
- Beads of condensation on the door frame at the lower corners — The same fault caught earlier, before the moisture has had time to freeze.
- An even sheet of frost across the whole rear wall — The compartment is running too cold rather than leaking air.
- A crust across the freezer walls — Humid air entering at the freezer door or drawer face.
- NEAR MISS - water under the crisper instead of frost — The same moisture, one stage further on; the water-leak page covers it.
Causes, most likely first on this family
- Fresh-food door racked on its hinges — First on this cabinet, because the door is tall, heavy when loaded and the last thing owners suspect.
- Compartment set colder than it needs to be — Second, and the cause of even frost rather than localised frost. Free to check and free to correct.
- Blocked drain refreezing meltwater — Third, and the fault that becomes a leak complaint if left.
- Freezer door or drawer not sealing — Fourth, and the source of freezer-side frost specifically.
- Stalled defrost cycle — Last, and the explanation when frost returns within weeks of a full manual clearance.
Check in this order, and why
- Note exactly where the frost is — First, because location names the cause on this cabinet more reliably than anything else.
- Test the fresh-food door with paper at the bottom corner and the top — Second. Grip at the top and release at the bottom is a racked door.
- Check what the compartment setting was changed to, and when — Third. Even frost across a whole wall is usually a setting rather than a seal.
- Look at the drain opening for a local build-up — Fourth. Ice collecting there alone means a blockage, not general frosting.
Before you open anything
Safety
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 frost off a rear wall or an evaporator with a metal tool - the tubing behind the liner punctures easily and a puncture ends the cabinet. Let it thaw with the doors open instead, and never use a heat gun.

When to call a technician
Call when frost returns within weeks of a full manual defrost on a cabinet whose doors seal and whose settings are correct, because that is a defrost heater, thermostat or control fault. Call also if the hinges will not bring a racked door back into line.
