The short answer
An export compact defrosts by hand and drains by gravity, and both of those depend on the cabinet standing where it was meant to stand. Ranked first on this platform: Condensation on a cold plate or rear wall. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- Water pooling at the bottom of the rear wall inside the cabinet — The pool sits directly below the surface that made it.
- Water at the front, and a door that swings open rather than closing itself — A door that will not self-close and a wet floor at the front are the same fault.
- Water at the door line, with condensation or frost around the same part of the seal — The wet patch marks where the air is coming in.
- NEAR MISS — water only appears after a power cut or a long door-open — That is melt from the evaporator finding its way out, and it usually needs no repair at all.
Causes, most likely first on this platform
- Condensation on a cold plate or rear wall — A static-cooled cabinet frosts its rear plate during the run and melts it during the off cycle by design. It ranks first on this platform because the whole drip path is a moulded channel with no pump and no heater behind it, so a cabinet standing out of level, or one whose channel has never been cleaned, puts its meltwater on the floor.
- The cabinet tilted so water runs the wrong way — Drains and pans rely on the cabinet standing level, or tilted very slightly backwards. It ranks second here because export cabinets are climate-class rated, and the class the unit was built for is frequently not the room it ended up in.
- Humid air entering past a door seal — A seal that is not sealing lets room air in continuously. That air is humid, it meets a cold surface immediately, and the water it drops runs down inside the liner and out under the door. Ranked third: worth checking once the causes above have come back clean.
Check in this order, and why
- Look at the channel at the foot of the rear plate and the hole in the middle of it — The hole is the narrowest part of the whole system and the first thing to check. It leads because it tests the top-ranked cause.
- Put a spirit level on the top of the cabinet, front to back — Two minutes, and it explains a leak that no part would have fixed. Tests the second-ranked cause.
- Run a slip of paper round the door seal and note where it pulls out freely — It maps the failure round the whole door in a couple of minutes. Tests the third-ranked cause.
What an owner can safely check
- Clear the channel and the hole with warm water and a soft flexible line — Keep food a hand-width off the rear plate afterwards so the melt can run.
Tools: warm waterAbout 25 min
- Adjust the feet so the cabinet sits level side to side and very slightly back — The door should swing gently closed from half open when you have it right.
Tools: spirit levelAbout 20 min
- STOP here if the next step needs a meter on live terminals or a sealed panel off — That is where an owner check ends. Write down what each check showed and hand it to the technician.
Before you start tracing it
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the base — a capacitor can hold a charge after the power is off, and water plus a live compartment is the one combination to take seriously.
When to call a technician
Call once the water is coming from behind a sealed panel, from the sealed system, or from a drain that will not clear from the cabinet side.

What this page does not cover
This page is written for the Multistar refrigerator as a class, not for one family or one model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: part numbers, wiring colours and disassembly order, which differ by family.
