Start here
Short answer: this is melted frost that has lost its route out. Start with a plug that has perished on this cabinet. A freezer has no supply line, so clean cold water arriving continuously is not a possibility here.
What you observe
- The floor is wet only every few hours — Periodic water follows the defrost cycle on a frost-free cabinet.
- A sheet of ice across the bottom of the cabinet — Defrost water freezing where it stands means the drain below it is blocked.
- Water at the back rather than the front — The drain outlet or the evaporation tray, both of which are at the rear.
- NEAR MISS — the water is warm or soapy — Warm or soapy water came from elsewhere in the room. Dry the floor, put paper down, and confirm the source before opening anything.
Causes, most likely first on a Kucht freezer
- A plug that has perished — Chest and manual-defrost cabinets have a drain outlet low at the front with a plug in it. After a defrost that plug is easy to leave out or to refit loosely, and then every subsequent thaw runs onto the floor. Number one here, because this is what the cabinet meets first and what owners notice last. The mechanism here is specified well above domestic duty, so the ordinary causes below outrank it by a wide margin.
- Seal letting humid air in, producing frost that melts — Every leak on this page is melted frost, and the seal is what decides how much frost there is. A gasket that no longer touches the frame admits humid room air continuously, and that air gives up its moisture as ice inside the cabinet. Second, and worth checking before anything is taken apart, since it is visible from outside the cabinet.
- Heavy frost melting after a warm spell or a power cut — It is also self-reinforcing: heavy frost reduces cooling, which lets the cabinet warm, which melts more frost. It ranks third: real, but rare enough that chasing it first wastes an afternoon.
- The drain tube packed with ice or debris — The blockage is usually at the very top of the tube, where a small plug of ice re-forms after each defrost, so clearing it is often a matter of warm water and patience rather than dismantling anything. Last, and the reason the order matters: it is the least likely of the four, and the three above are quicker to settle.
What to check first, second, third
- Check the plug seats fully and squarely — A plug pushed in at an angle leaks slowly rather than obviously. Start here — it is free, and it decides which half of the list you are in.
- Shut the lid or door on a sheet of paper at several points and pull — Paper that slides out easily marks the leak path, and frost usually forms at the same spot. Next, because it takes the same few minutes and covers the other likely half.
- Ask whether there has been a power cut or a door left open recently — That history explains a one-off leak with nothing wrong at all. Third in sequence — useful, but rarely where the answer turns out to be.
What to do, step by step
- Refit or replace the drain plug and dry the area — Keep the plug with the cabinet rather than in a drawer after the next defrost.
Tools: clothAbout 15 min
- Repack so nothing holds the lid or door open — One packet proud of a basket keeps the cabinet making frost all night.
About 20 min
- Empty the cabinet and defrost it completely with towels down — Let the ice melt rather than chipping at it: the tubing behind the liner is thin.
Tools: towels, coolerAbout 120 min
- STOP if the fault is now down to a sealed or high-voltage part — Those need tools, training and a discharge procedure. Write down what you found and hand it over.

Safety
Unplug the freezer or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never chip ice off a wall or a coil with a knife or a screwdriver: the tubing behind the liner is thin, and puncturing it releases the charge and ends the life of the cabinet.
When to hand it over
Stop and call at the point where the fix means dismantling the interior. Before that, a full defrost and a clean drain resolve most of these complaints on a cabinet of this kind.

What is not on this page
A note on scope: this page treats Kucht freezers as one class. A page written for your specific family or model line will carry what this one deliberately leaves out — component locations, fastener sizes and the disassembly order — and it takes precedence over this page for your unit.
