The short answer
On the Ariston ARWXF washer line, water that will not drain is worth working through in a set order: a blocked pump filter or coin trap first, then a drain hose that is kinked, too high, or pushed too far into the standpipe, and only after those does the work that needs a meter or a teardown enter the picture. That order is written for a one-cabinet line and sequenced for how these models are put together, which is where it departs from the brand-generic article.
What you observe
- The drum is full at the end and the pump can be heard trying — A pump working with no water moving is the signature of a blockage rather than a failure.
- The problem started right after the machine was moved — A hose crushed against a wall is the classic post-move drainage fault.
- NEAR MISS — water is on the floor rather than in the drum — That is a leak and it has its own page; deal with the water before the drainage.
Causes, most likely first on the ARWXF line
- The pump filter or coin trap is blocked — The first thing to suspect: the filter exists precisely to catch what the pump cannot pass, and once it is full of lint, coins and hair the machine can no longer move water at all — which is why it is the first thing to open on any machine that will not drain.
- The drain hose is kinked, too high, or pushed too far into the standpipe — The drain hose is crushed or badly positioned often enough that it is worth checking before anything is opened.
- The pump impeller is jammed or the pump housing is blocked — A jammed impeller buzzes rather than pumps, and that noise separates it cleanly from a dead pump.
- The lid switch or door lock is preventing the drain and spin step — The lid switch is the explanation when the wash completes normally but drain and spin never happen at all.
- The drain pump motor or its control — Last here, and the only cause on this list that is not owner work — a pump that is silent at the drain step, with a clean filter and a free impeller, has lost its motor or its supply — and that is diagnosed with a meter on live terminals.
Check in this order, and why
- Open the pump filter and look at what comes out — Lint, coins, hair and buttons are the normal haul, and they are also the answer. Done first because it separates the likeliest causes before any tool is needed.
- Pull the machine out and follow the drain hose along its whole run — Second: it confirms or dismisses what the first check suggested.
- With the power off, reach into the filter housing and turn the impeller by hand — Third, once the two checks above are clean.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before opening the pump filter — a capacitor can hold a charge after the power is off, and the filter housing sits close to the electrics. Expect a lot of water: a full drum empties through that filter, so work with a shallow tray and towels and unscrew slowly. Never force a locked door on a full drum.

When to call a technician
Call when the filter is clean, the impeller turns freely, the hose is clear and the pump is silent at the drain step, because that is the pump motor or its supply. Drain the machine down first so the drum is manageable.
