The short answer
Water inside a thermoelectric Aicook is almost always condensation on a plate that is cold continuously and never defrosts. Wipe it out as routine, cover everything you store, and open the door less. Condensation on the outside is next and is the same effect. A blocked drain, where one exists, is third, and a cracked cabinet last.
What you observe
- A steady film of water in the base inside — Condensation collecting with nothing to clear it.
- It is worse in a humid room or in summer — More moisture in the air reaching the plate.
- The outside of the cabinet beads too — The same effect on the other side of the wall.
- Uncovered food or drink stored inside — A continuous moisture source in a sealed box.
- NEAR MISS — frost on the plate itself — Normal on the coldest surface. Not a leak.
Causes, most likely first on this class
- Condensation on a continuously cold plate — First because this class never cycles off, so the plate is always collecting and there is never a defrost period to clear it. Nothing has leaked; the water was always in the air.
- Warm damp air entering, and uncovered contents — Second, and it is what sets the rate: every door opening brings in room air, and anything stored uncovered keeps feeding moisture to the coldest surface in the box.
- Condensation on the outside of the shell — Third, and not a fault either: a cold cabinet in a humid room beads on the outside, which wets whatever it is standing on rather than anything inside.
- Drain blocked, or the cabinet cracked — Last. Where a drain exists it silts easily; a genuinely cracked cabinet is rare and, at this price point, ends the unit.
Check in this order, and why
- Decide whether the water is inside or outside — Free, and it separates two different answers.
- Look at whether contents are covered — Uncovered food feeds the plate continuously.
- Note how humid the room is and how often it is opened — Both set how fast the water accumulates.
- Check for a drain and clear it if there is one — Left until here because many units have none.
What an owner can safely check
- Wipe the cabinet out and dry it completely — Then note how long it takes for water to return.
Tools: clothAbout 20 min
- Cover or seal everything stored inside — Uncovered drink and food is a constant moisture source.
About 15 min
- Reduce door openings for a day and compare — Fewer openings means much less moisture arriving.
About 20 min
- Look for a drain opening and flush it if present — Use warm water and nothing sharp.
Tools: jugAbout 20 min
- STOP HERE if water escapes the cabinet itself — A cracked cabinet is a replacement at this price point.
Before you open anything
Safety
Unplug the unit before wiping out the base, clearing vents or opening the case; a capacitor can hold a charge after the power is off, and the fan can restart without warning while power is connected. Keep water away from the adapter and the lead, which usually sit on the same surface. Never chip frost off the plate with a tool.
When to call a technician
Call rarely here. If the contents are covered, the room is reasonable, any drain is clear and water still escapes the cabinet, the cabinet itself has failed and a replacement usually costs less than a visit. Move the unit onto a mat and off furniture in the meantime. Unplug it immediately if water reaches the adapter or the lead.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: drain positions, cabinet and seal part identifiers, cooling margins and fault-code meanings, all of which differ between the thermoelectric, compressor and vehicle-lead families.
