The short answer
The Ariston ARWXF washer family covers four listings in the roster below, and on that platform whether the pump can be heard running splits the shortlist in half. A washer that will not drain is one of the few appliance faults where the most likely cause is also the easiest one to reach. Where the machine also refuses to spin, that is the same fault seen from the other end: no washer spins on a full drum.
What an owner actually sees
- No sound at all where the pump should be — Either the pump is not being asked to run or it cannot. A jammed impeller stops the motor dead, and that silence is easy to mistake for a control fault.
- The cycle ends with the laundry still soaking — The machine abandoned the spin because the drum was not empty. This is the same fault reported from the laundry rather than from the drum.
- A smell from the drum between washes — Water standing in the pump housing and the hose is what produces it, and the smell often arrives weeks before the drain finally stops altogether.
- NEAR MISS — the waste pipe gurgles and backs up when other taps run — That is the household plumbing rather than the machine, and the bucket test on the standpipe will settle it in two minutes.
Causes, most likely first on the ARWXF line
- Pump filter blocked with lint, coins or debris — Ranked first here: it is the first restriction on the way out and it is designed to be opened by hand, which is why it is both the most likely cause and the cheapest one to rule out. 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.
- Drain hose kinked, crushed or badly routed — Second here: it is created by pushing the machine back into its space, so it appears with no warning after a move and is invisible from the front.
- Standpipe or waste connection blocked or siphoning — Third here: the fault is in the plumbing rather than the appliance, which is why it survives every repair to the machine: a hose pushed too deep or a blocked standpipe will defeat a perfectly good pump.
- Pressure sensing telling the machine the drum is already empty — Last here: the machine never asks the pump to run, so the pump is silent and blameless, which is the one case where silence does not mean a jam.
Check in this order, and why
- Listen for the pump during the drain step — A hum or a whirr with no water moving is a blockage past the pump; complete silence is either a jammed impeller or a pump that is not being asked to run.
- Turn the impeller by hand with the power off — Behind the filter the impeller should turn freely with a finger. One that will not move is jammed; one that turns loosely with no resistance may have lost its coupling.
- Lower the drain hose into a bucket on the floor — If the drum empties by gravity, the pump and the filter are clear and the fault is the height, the routing or the waste connection rather than the machine.
- Run a drain or spin programme and watch the whole sequence — With the filter clear and the hose proven, a drain programme shows whether the machine asks the pump to run and whether the water leaves in the time it allows.
Before you open anything
Safety
Switch off at the wall and let a hot cycle cool before the filter cover is opened: a capacitor can hold a charge after the power is off. The filter holds a surprising amount of water and on a hot programme that water can scald, so let the machine stand until it is cool and have a shallow tray and towels ready before the cover moves. Objects in a pump can have sharp edges; use a torch rather than a bare finger to find them..

When this stops being an owner job
Call when the filter is clear, the impeller turns freely and the standpipe takes a bucket of water without backing up, since what is left is the pump itself or the circuit that drives it. Anything that puts water on the floor is a same-day problem; anything that only costs a wash cycle can wait for a convenient appointment.
