What this usually is
Puddles under the unit and a sheet of ice under the crisper are the same fault at two different stages. Clearing a drain is really homeowner work and needs nothing more than warm water and patience. On this kind of cabinet these cabinets are old enough that age, not design, sets the failure order — seals harden, terminals oxidise, mechanical timers wander.
What you actually observe
- A smell of damp or mould near the base — Standing water somewhere it cannot evaporate, typically under a drawer or beneath the liner.
- NEAR MISS — water on the outside of the door only — That is condensation at a failed seal, and the door-seal page covers it.
- Drips from the underside of the freezer compartment — Melt water escaping past the drain trough rather than through it.
- Damp or swollen flooring in front of the unit — The leak has been running for a while; the floor tells you how long before you find the source.
Likely causes in order
- Defrost drain blocked with debris or frozen shut — Ranked first: It explains the two hallmark signs together — ice under the drawers and water on the floor — which no other cause does as neatly. It sits at the top here since these cabinets are old enough that age, not design, sets the failure order — seals harden, terminals oxidise, mechanical timers wander.
- Door seal leaking and condensing air inside the unit — Second: A gasket fault and a drain fault together is a common pairing, since each makes the other worse.
- Cabinet out of level so water runs forward — Third: It is the cheapest cause to eliminate and it costs nothing but a spirit level and five minutes.
Check in this order, and why
- Check the drain pan at the back of the unit — A dry pan with a wet floor proves the water never got there; a brimming pan says something else is wrong.
- Run the paper test round the door — A leaking seal loads the drain with condensation that it was never meant to handle.
- Ask what changed just before the problem appeared — A move, a power cut or a new installation nearby explains a large share of sudden cold-appliance faults.
What an owner can safely do
- Flush the drain again a week later to establish it stays clear — A drain that reblocks quickly is telling you there is debris further along than warm water can reach.
Tools: warm waterAbout 15 min
- Chip nothing: melt the ice sheet under the drawers — Empty the compartment and let the ice melt naturally, or use warm cloths. Prising it out cracks the liner.
Tools: warm cloths, towelsAbout 30 min
- Clear the drain with warm water and a soft flexible tube — Pour slowly and let the warmth do the work. Never use a metal wire or a sharp tool — a punctured trough turns a free fix into a repair.
Tools: warm water, turkey baster or soft tubingAbout 25 min
- STOP once the free tests are exhausted — The next step is a measurement rather than an observation, and measurements here are technician work.
Safety first
Safety
Pull the plug, or trip the breaker that feeds the outlet, before any panel comes off; a stored charge can sit in a capacitor long after the lights go out. Sealed-system work — the compressor, the condenser and the lines between them — belongs to a licensed technician with recovery gear. Nothing in the sealed circuit is an homeowner job: it is pressurised, and the law treats venting it as a violation in its own right.
The line between fix and call
If the drain reblocks within days of being flushed, stop flushing — repeated blockage means debris beyond reach or a drain heater that has stopped working. If the part that is probably needed costs a serious fraction of a replacement, get the cause named in writing before agreeing to anything.

The page is deliberately family-agnostic: one Coldspot refrigerator can share nothing with the next but the badge. Where a family or model page exists, it is linked below and it is the page to trust for dimensions, fasteners and parts. Read this one for the shape of the problem, and the specific page for the specifics. It also does not cover installation faults that look like appliance faults, which are handled on the pages for the problem they imitate.
