The short answer
Water in or under a Blomberg integrated freezer is defrost meltwater that has missed its drain or overwhelmed its tray. A blocked drain is the leading cause, a door held ajar by a dropped furniture panel is the second, and both should be dealt with quickly because the water damages the kitchen, not the appliance.
What you observe
- A slab of ice under the bottom drawer — Meltwater freezing where it pools instead of draining.
- Water running out under the furniture door — The tray is overwhelmed or displaced.
- A swollen plinth or damp cabinet base — A slow leak that has run unseen for weeks.
- NEAR MISS — heavy frost with soft food — Then a cooling fault is producing the water.
Causes, most likely first on this brand
- A blocked defrost drain — First: crumbs and packaging debris silt the drain hole and channel, and meltwater that cannot reach the tray pools in the base and freezes.
- A door held ajar by the furniture panel — Second, and specific to this fitting: a dropped panel keeps the appliance door a fraction open, humid air pours in continuously and the drain cannot cope with the meltwater it produces.
- A displaced or overwhelmed drip tray — Third. The tray sits above the compressor, and an integrated unit that has been slid in and out for other work often has it knocked out of place.
- A failed defrost cycle — Last. Ice builds until it overwhelms the drain entirely, and the water then goes wherever gravity takes it.
Check in this order, and why
- Decide whether the water is inside the cabinet or under it — Inside points at the drain, under points at the tray.
- Close the door on paper at several heights — This tests the seal and the panel alignment together.
- Clear and flush the drain hole — The leading cause and the fastest thing to correct.
- Check the tray once the plinth is off — Displacement after other work is common here.
What an owner can safely check
- Switch off at the isolation switch and empty the lower basket — You need clear access to the drain channel.
Tools: cloth, torchAbout 20 min
- Flush the drain with warm water and a soft wire — Never force a sharp tool into the hole.
Tools: warm water, soft wireAbout 25 min
- Remove the plinth and re-seat the drip tray — It should sit square and clear of the compressor shell.
Tools: screwdriver, torchAbout 25 min
- Adjust the furniture panel so the door closes fully — Then re-test with paper all the way round.
Tools: screwdriver, paperAbout 30 min
- Dry the cabinet base and plinth thoroughly — Trapped water ruins joinery quietly over months.

Safety
Switch the freezer off at its isolation switch before flushing the drain or removing the plinth — a capacitor can hold a charge after the power is off, and an integrated appliance has no reachable plug. Never chip ice with a sharp tool; the evaporator is behind that wall. Dry the joinery fully, because water trapped under a fitted cabinet is not visible until the damage is done.
When to call a technician
Call when the drain runs clear, the tray is seated, the door closes and seals and water still collects. Call the kitchen fitter rather than a technician if the furniture panel cannot be adjusted to let the door close. Call promptly in any case, because on an integrated appliance the cabinets and flooring are what the water is damaging.

This page covers Blomberg integrated freezers as a class rather than one model line. Deliberately absent here: drain and tray part identifiers, housing clearances, gasket profiles and capacity figures, which differ by family and belong on the family or model page.
