The short answer
Water at a compact upright freezer usually comes down to one thing: the cabinet is tilted away from its drain. Next on the list: defrost melt water overrunning what is there to catch it. Before anything else, establish whether the water is inside the cabinet or on the outside of it — those are two entirely different faults.
What you observe
- Water where there was none before — Inside the cabinet, at one low corner, or beaded on the outside — each means something different.
- The leak began after the cabinet was moved — Nothing failed; the geometry changed.
- A large puddle on the day the cabinet was defrosted — Timing alone identifies this one.
- Ice or water builds at one point on the door — Warm air is getting in at that point and nowhere else.
- NEAR MISS — the cabinet is also failing to hold temperature — Read the cooling page first: a warm freezer that leaks is one fault with two symptoms.
Causes, most likely first on this machine
- The cabinet is tilted away from its drain — First on this unit, because it stands in a spare room or a landing, and it is moved more often than a full-size unit and has been moved. The internal channel depends on a very small fall; tip the cabinet the wrong way and the water runs to a corner with no drain in it.
- Defrost melt water overrunning what is there to catch it — Ranked here because it happens on every defrost unless the water is managed part-way through.
- A leaking seal is letting humid air in to condense — Ranked here because a seal fault leaks water as readily as it leaks cold, and only one of those is obvious.
- The condensate pan is cracked, full or out of position — Last, and worth a look while the coil is being cleaned anyway.
Check in this order, and why
- Put a level across the cabinet in both directions — The drain relies on a small fall and a tilt defeats it.
- Note whether the water appeared during or after a defrost — The tray on this class cannot hold a whole defrost at once.
- Paper-test the seal and look for water inside the door — Water on the door rather than the floor means condensation.
- Isolate the cabinet and check the pan is square and whole — Everything that drains ends up here.
What an owner can safely check
- Dry everything and find out where the water reappears first — Inside, at a corner, or on the outside — the first wet point is the answer.
Tools: towelsAbout 20 min
- Level the cabinet with the drain corner very slightly low — Recheck after a day of normal use.
Tools: spirit levelAbout 20 min
- Lay towels and empty the tray part-way through any defrost — Plan for several trayfuls, not one.
Tools: towels, bowlAbout 25 min
- Paper-test the seal all round and clean the gasket channel — Wherever the paper slides free is where air is entering.
Tools: paper, clothAbout 15 min
- STOP HERE before removing a rear panel or disturbing any pipework — Water and live terminals in the same space is a service job.
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 ice off the walls of the cabinet. Refrigerant tubing runs inside those panels and a puncture scraps the freezer outright — let it melt with the door open instead.
When to call a technician
Call once the drain and the seal are proven good, the cabinet is level and water still returns inside it. Call sooner if the water is reaching a socket or running under another appliance. Call immediately if water is touching any electrical connection — switch the circuit off before you mop.

What this page does not cover
This page is written for the brand and the cabinet class, not for one family or model line. Where a family- or model-specific page exists for your freezer, that page is the more specific answer. Deliberately absent: capacity figures, thermostat and relay part identifiers, wiring colours and climate-class ratings, which differ between the compact upright and drawer families.
