The short answer
On the Ariston ARWXF washer line, a cycle that will not complete is worth working through in a set order: a door lock or lid switch that is not confirming first, then a restricted drain stretching or repeating steps, 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 cycle will not begin and the door stays locked or will not latch — The interlock is both the first thing the machine checks and the thing that keeps the door shut.
- The cycle runs far longer than it used to and water is slow to leave — Time stretching without an error is nearly always drainage rather than control.
- NEAR MISS — the drum is full of water at the end — That is a drainage fault and the drainage page ranks those causes in a better order.
Causes, most likely first on the ARWXF line
- The door lock or lid switch is not confirming — Ranked first: a washer will not run a step it cannot do safely, so a lock that closes but does not report closed leaves the machine stalled before it starts — and the tell is that the door is also often still locked when you try to open it.
- A restricted drain stretching or repeating steps — A restricted drain makes the machine repeat steps until the water leaves, which stretches the cycle without any obvious fault.
- Programme selection, a child lock or a paused cycle — A selection, a delay timer or a child lock explains an idle-looking machine more often than any fault does.
- Slow or partial fill from closed taps and blocked inlet screens — The fill side is still worth confirming at the end, because a slow tap stretches every cycle on the machine.
- The control board, a sensor or the motor control — Last here, and the only cause on this list that is not owner work — a board that resets mid-cycle, a heater or level sensor reading wrongly, or a motor control cutting out is diagnosed with a meter on live terminals, which is where owner work ends.
Check in this order, and why
- Close the door firmly and listen for the lock engaging — No click at all, or a click followed by nothing, both point here. Done first because it separates the likeliest causes before any tool is needed.
- Watch a drain step and time how long the water takes to go — Second: it confirms or dismisses what the first check suggested.
- Read the panel carefully and cancel the programme completely — 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 or removing any panel — a capacitor can hold a charge after the power is off. Never force a door that is still locked: the lock releases when the drum has stopped and the water is out, and forcing it breaks the one part that was working. Shut the taps before unscrewing any inlet hose.

When to call a technician
Call when the taps, the screens, the filter, the hose and a full cancel have all been done and the cycle still will not complete, because what is left is the control side. Bring the list of where it stopped each time.
