The short answer first
On a Marathon refrigerator, water where it should not be is most often an overflowing or displaced drip tray rather than a cabinet tilted so water runs the wrong way. The installation comes first, because a compact cabinet fitted tightly into its space is rarely standing as the drain path expects. All three checks below are owner work, and not one of them needs a part.
What you are seeing
- Water under the crisper drawers with a dry floor — Water inside and nothing outside points at the drain path rather than the plumbing.
- A sheet of ice across the floor of the freezer — Ice rather than water means it is freezing where it lands, which points at a fill or drain problem.
- Ice forming at the bottom of the door — Water that reaches the door and freezes there means it never got to the drain.
- NEAR MISS — water and the cabinet is also warm — Water with warmth is a cooling fault first; the cooling page ranks it correctly.
What goes wrong here, in order
- An overflowing or displaced drip tray — The tray above the compressor is meant to evaporate the defrost water. Cracked, knocked out of position when the cabinet was last moved, or simply overwhelmed in a humid room, it spills onto the floor at the back. It leads because the water is at the back and on the floor, and that combination 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 leaking water line, valve or filter connection — Cabinets plumbed for ice and chilled water carry a line to a valve at the back and on to a filter head. Any of those joints can weep, and the water runs down the back and appears at the front as a puddle. It sits here because it is quick to confirm with a dry cloth and a torch, and because it is the cause that gets worse rather than better.
- A cabinet tilted so water runs the wrong way — Interior drains and trays rely on the cabinet standing slightly back-tilted. Tipped forward on an uneven floor, water that should reach the drain runs to the door instead. It is last because a cabinet that has never moved is usually still standing as it was set.
The order to check in
- Look underneath at the tray above the compressor — Cracked, overflowing or knocked askew is visible from the front with the grille off. First, because it is the likeliest to end the job.
- Dry the back of the cabinet, then look again with a torch after an hour — A wet joint on a dry background is unmistakable, and it tells you which joint. Second, once that is clean.
- Check the cabinet stands slightly back-tilted rather than forward — A forward tilt sends water to the door instead of the drain. Third, and by now the answer is usually in hand.
The steps, with tools and times
- Pull the base grille, remove the tray, empty and reseat it — Check it sits flat in its cradle and is not cracked.
Tools: clothAbout 20 min
- Shut off the supply at the valve, then dry and inspect each joint — Isolate first and check afterwards, in that order.
Tools: cloth, torchAbout 20 min
- Adjust the front feet until the cabinet sits slightly back — A small back-tilt is what the drains were designed around.
Tools: spirit levelAbout 15 min
- STOP — isolate the water supply and note where the water collects — Where the water sits is the single most useful thing you can hand a technician.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Shut the water supply off at its valve before touching any plumbed joint; a fitting that lets go under pressure empties into a kitchen faster than you can reach the stopcock.
When to call a technician
The line is the sealed system and the concealed plumbing. A drain cleared from inside, a tray reseated, a filter turned home and a gasket cleaned are all yours; a weeping valve behind a fitted cabinet is not. On this brand the brand has a real parts channel behind it, which makes a proper diagnosis worth the effort.
