The short answer for these models
A leaking washer is almost always losing water at a connection rather than through the tub. Hose couplings, the drain hose where it enters the standpipe, and the door or lid seal account for most of these, and all three are visible with a torch while the machine runs. Overdosed detergent is the fourth, and it looks like a leak without being one. What changes on the MAV models is the sequence rather than the diagnosis. A tap-adapter installation gives up its pressure and its drain height the moment the adapter slips, so a fault that looks electrical on a plumbed machine is usually mechanical on a portable one, which is why the supply and adapter checks belong at the top of the list here.
What you observe
- How your MAV unit is built — the check that comes before the list — See where the water comes from. On a portable installation two failure points sit outside the machine and imitate faults inside it.
- Foam coming out of the dispenser or the door — Foam rather than water, escaping wherever it can, which is a dosing error dressed as a fault.
- Water tracking along the floor from behind the machine — A trail running forward from behind the cabinet, telling you nothing except that the source is at the back.
- NEAR MISS — the tub is full at the end but the floor is dry — That is a drainage failure, not a leak, and the page about a machine that will not empty covers it.
Causes, most likely first on this family
- The door seal or the lid gasket — Here because a hair grip in the fold or a hardened lip lets a thin stream out at the one moment nobody is watching. The ranking moves here for a reason particular to these models: how the unit is built changes what this finding means. That is what puts the supply and adapter checks ahead of everything else on the list.
- The tub, the sump or an internal hose — Last, because an internal split is far rarer than a connection fault and because confirming it means the cabinet off.
Check in this order, and why
- First — dry the floor and run one cycle watching with a torch — Do this before moving anything: a leak you have watched is a leak you can find. On these models this is the step the construction changes: what you found at the step above decides how much weight to give what you find here.
- Second — check every connection at the back — Most leaks are at a joint, and every joint on this machine is behind it.
Before you open anything
Safety
Kill the power and close the supply valves before anything is moved — a capacitor can hold a charge after the power is off. Do not pull the machine out across a wet floor on its own feet; dry the path, get help, and walk it.
Where the owner job ends
Call once the connections, the seal and the dosing are all accounted for and water is still arriving from somewhere you cannot see, because an internal hose or a cracked sump means the cabinet off. Shut the taps and stop using the machine in the meantime — a leak that runs unattended reaches the floor below long before it reaches your notice.
