The short answer
On a Marathon washing machine, water on the floor is most often a drain hose split, loose at the standpipe, or backing up rather than a loose or perished inlet hose connection. The installation comes first on a compact machine, because the design assumes a solid square footing that a tight laundry space rarely provides. All three checks below are owner work, and not one of them needs a part.
What you are seeing
- The leak started after the machine was moved — Moving disturbs hoses and clips, and it disturbs the level.
- Water only during the drain phase — Drain-phase water belongs to the drain hose and the standpipe.
- Water underneath with the outside dry — A leak that appears from underneath is internal and needs a panel off.
- NEAR MISS — the drum is full and will not empty — Water inside rather than outside is a drainage fault on its own page.
Causes, most likely first on this brand
- A drain hose split, loose at the standpipe, or backing up — The drain hose sees a surge every time the pump runs. A split, a clip that has worked loose, or a standpipe that cannot take the flow all put water on the floor during the drain phase only. It leads because the timing narrows it: water only while draining belongs to the drain path and nowhere else. The machines are chosen for tight spaces, so they are usually boxed in on at least two sides.
- A machine out of level, or overfilling — An unlevel machine slops water past the door during spin. A pressure system reading the level wrongly overfills, which shows as water at the drawer and the door with the machine otherwise healthy. It ranks here because levelling is free and worth doing before any panel comes off.
- A loose or perished inlet hose connection — The fill hoses carry mains pressure whenever the tap is open, so a washer that only leaks on fill is almost always leaking at a hose end. Rubber washers harden and connections work loose with vibration. It is last because the water appears with the taps closed, which rules it out.
The order to check in
- Watch the hose and the standpipe through a drain phase — The surge shows up a split or a loose clip immediately. First, because it is the likeliest to end the job.
- Rock the machine and watch the water level through the door — Rocking, or a level above the glass, are both visible without a tool. Second, once that is clean.
- Dry both hose ends and look again after a fill — A wet joint on a dry background tells you exactly which one. Third, and by now the answer is usually in hand.
The owner-side checks
- Check the hose along its run and secure it at the standpipe — Look for splits at the bends, which is where they always start.
About 20 min
- Level the machine on its feet and rerun a short cycle — A firm floor under all four feet matters as much as the feet do.
Tools: spirit levelAbout 25 min
- Close the taps, then check and tighten both hose ends — Replace a hardened rubber washer while you are there.
Tools: clothAbout 20 min
- STOP — note exactly when in the cycle the water appears — The phase the water belongs to is most of the diagnosis, and it is free to record.
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. Close the water taps before touching any hose: an inlet hose that lets go under mains pressure empties into a room faster than you can reach the stopcock.
Where the owner fix ends
Call when the water arrives from underneath with every external joint dry, when the machine overfills past the glass, or when a leak returns after hoses, seal and filter have all been dealt with. Everything else on this page is owner work. On this brand the brand has a real parts channel behind it, which makes a proper diagnosis worth the effort.
