The answer first
The Ariston ARWL washer family covers six listings in the roster below, and on that platform the pressure side and the gravity side leak in completely different ways. A washer leak is diagnosed by its schedule: fill, spin or idle, because each names a different pressure regime in the machine. A leak that appears only on spin is a different shortlist from one that appears while the machine stands idle.
The observables
- Water is on the floor even when the machine is idle — Something upstream of the machine is weeping under mains pressure, and it will not stop until the taps are closed, which makes it the most urgent form of this fault.
- Foam rather than water at the door or under the cabinet — Excess suds escape past seals that water alone would never pass. The fix is dosing rather than parts, and the evidence is the foam itself.
- Water only on one particular programme — A programme that fills higher, uses a different compartment of the dispenser or spins faster will expose a leak that gentler programmes do not.
- NEAR MISS — water at the door with no leak anywhere else — Condensation and splash from an overloaded drum both wet the door area without being a leak, so confirm the water is arriving rather than escaping.
Causes, most likely first on the ARWL line
- Inlet hose fittings or the tap connection — Ranked first here: these are the only joints on the machine that are under mains pressure all the time, so a leak here runs whether or not the machine is in use and delivers far more water than any other cause on the list. The wildcard tails on this roster are finish and trim, not mechanism, so a difference in what you see on the outside is not a reason to expect a different cause inside.
- Door seal split, perished or trapping debris — Second here: it takes the water, the grit and the door closing on laundry, and it fails at the lowest point where all three collect.
- Hose clip or fitting inside the cabinet working loose — Third here: the internal hoses move with the drum every spin, so a clip that has relaxed leaks under movement and seals again at rest.
- Detergent over-dosing producing foam that escapes — Fourth here: foam goes where water cannot, so the machine appears to leak from a seal that is in perfect condition and a part gets replaced for nothing.
- Dispenser drawer or its housing overflowing — Last here: the siphon in the drawer has to clear itself every wash, and residue eventually stops it, at which point the water backs out of the front instead of going down.
What to check first, second, third
- Establish when the water appears — Fill, wash, spin or idle. Each names a different pressure regime in the machine, and that single observation rules out most of the shortlist before anything is moved.
- Run a fill-only and then a spin-only cycle — Separating the two pressure regimes tells you whether the leak belongs to the supply side or to movement, and it needs nothing but two short programmes.
- Pull the drawer out and look into its housing — Residue in the siphon, or a housing crusted with detergent, makes water back out of the front of the drawer on fill, which is easy to see once the drawer is out.
Before you open anything
Safety
Dry the floor and unplug the appliance or switch off its breaker before working at the back: a capacitor can hold a charge after the power is off. Water at the base of the cabinet is where the mains connections are, so the machine comes off supply before it comes out of its space. Do not kneel in a wet floor to work, and expect a supply hose to hold pressure for a moment after the tap is shut..

Where the owner side ends
Call once the hose fittings are dry, the filter cover seats, the seal is intact and the dispenser is clear, because what remains is the tub seal or the pump housing and both are behind the drum. Close the taps now if the floor wets while nothing is running, and keep them closed between washes until the repair is made.
