The short answer
Water inside the cabinet or on the floor: on an Igloo freezer that is usually months of frost melting at once, not a cracked interior trough. If that is clean, a blocked defrost drain is next. Most causes below are owner checks needing no tools and no panel off; the last is a service call.
What you are looking at
- Water runs down the outside of the cabinet — The shell is wet rather than the interior.
- Packages at the bottom are wet or frozen together — Water pooled around them and refroze.
- There is a sheet of ice on the cabinet base — Melt water froze where it pooled.
- NEAR MISS -- water after a power cut — That is stored frost melting, not a drain fault.
Causes, most likely first on this kind of unit
- Accumulated frost is melting — Frost that built up over months melts whenever the cabinet warms -- a power cut, a door left ajar, or a warm spell. Ranked first on an Igloo compact or chest cabinet: on a cabinet that defrosts only by hand, melting frost is the usual answer to water on the floor.
- The defrost drain is blocked or frozen — Melt water has one route out of the cabinet. Placed here: a blocked route puts defrost water exactly where owners find it.
- The seal is letting humid air in — A leaking gasket admits warm humid air that condenses and freezes on the nearest cold surface, then melts and runs. Ranked here because condensed room air is water that never came from a pipe.
- The interior trough, heater or hose behind the panel — A cracked trough, a failed drain heater or a split internal hose needs the panel off and the cabinet thawed to reach. Bottom of the list, deliberately: it needs a panel off and a meter on a heater circuit, which is why it is last.
Check in this order, and why
- Judge the frost, and ask what changed — Thick frost plus a recent warm spell or open lid explains the water without any fault.
- Look at the drain mouth and the trough — Ice or sludge at the drain with water standing behind it is the confirmation.
- Only after the accessible routes are proven — Water returning with a clear drain, a level cabinet and a good seal points behind the panel -- a service call.
What an owner can safely check
- Mop up and find out where it returns first — Dry inside and out, check both an hour later, and let the first wet spot name the source.
Tools: towelsAbout 15 min
- Check the drain plug, hose and pan — Seat the plug, confirm the hose ends in the pan and that the pan is not cracked.
Tools: flashlightAbout 15 min
- Paper-test the seal and level the cabinet — Fix the failing stretch and set the feet so it sits level front to back.
Tools: levelAbout 20 min
- STOP HERE -- the next step needs the panel off — Interior troughs, drain heaters and hoses behind the panel are technician work.
Before you open anything
Safety
Power off at the plug or breaker first, and let a loaded cabinet warm on its own rather than forcing ice off with steel.
When to call a technician
Anything you can reach without a panel is owner work; anything behind a panel or on the sealed system is not.

What this page does not cover
This page covers the Igloo freezer as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: drain-plug locations, trough geometry, heater part numbers and panel-removal order, all of which differ by family.
