What this usually is
On a Marathon freezer, water where it should not be is most often an evaporation tray overflowing or out of position rather than a blocked defrost drain. The installation comes first on a compact cabinet, because it is rarely standing as squarely as the drain path assumes. All three checks below are owner work, and not one of them needs a part.
What you observe
- A puddle on the floor at the back — Behind the cabinet is the tray's territory, and it is reachable from the front.
- Water at the front of the cabinet only — Water at the front has usually run forward rather than reaching the drain.
- A sheet of ice across the bottom of the cabinet — Water freezing where it collects means the drain is not taking it away.
- NEAR MISS — the sound of water running and nothing visible — Defrost water reaching the tray sounds exactly like this and is normal.
Why this happens, likeliest first
- An evaporation tray overflowing or out of position — The tray above the compressor is meant to evaporate defrost water. Cracked, knocked askew when the cabinet was last moved, or simply overwhelmed in a humid room, it spills onto the floor at the back. It leads because water at the back with a dry interior points at the tray before anything else. The machines are chosen for tight spaces, so they are usually boxed in on at least two sides.
- A cabinet tilted so water runs to the opening — Drains rely on the cabinet standing level or slightly back. Tipped forward, water that should reach the drain runs to the front and out at the seal instead. It ranks here because levelling is free and worth doing before anything is dismantled.
- A blocked defrost drain — Water from each defrost should run out through a small drain to a tray. Plugged with debris or frozen shut, it backs up and collects in the bottom of the cabinet, where it freezes into a sheet. It is last because the water is clearly outside the cabinet.
Check in this order, and why
- Pull the base grille and look at the tray — Cracked, full or knocked out of position is visible straight away. First, because it is the likeliest to end the job.
- Check whether the cabinet tips forward — A forward tilt sends water to the opening instead of the drain. Second, once that is clean.
- Find the drain hole in the bottom of the cabinet and look at it — Ice or debris sitting in it is the whole answer. Third, and by now the answer is usually in hand.
What an owner can safely check
- Remove, empty and reseat the tray — Check it sits flat in its cradle and is not cracked.
Tools: clothAbout 20 min
- Level the cabinet, slightly back rather than forward — That is what the drain path was designed around.
Tools: spirit levelAbout 15 min
- Clear the drain with warm water poured gently into it — A baster works well. Never force anything stiff down a drain hole.

- STOP — dry the floor and note where the water collects — Where the water sits is the single most useful thing you can hand a technician.
Safety first, and it is not a formality
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Dry the floor and isolate the cabinet before kneeling to work: water and an electrical appliance sharing a floor is the one combination worth taking seriously.
The line between a fix and a call
Call when the drain will not clear from inside, when water returns after the tray has been reseated and the cabinet levelled, or when the leak comes with the contents softening. Everything else here is owner work. On this brand the brand has a real parts channel behind it, which makes a proper diagnosis worth the effort.
