The short answer
The Ariston ARWL washer family covers six listings in the roster below, and on that platform the door interlock accounts for more of these than anything else. The most useful observation is whether anything at all lights up, because a completely dead machine and a lit machine that refuses to run share almost no causes. Supply, door lock and the panel itself account for the overwhelming majority, and all three are free to check.
The observables
- No lights, no display, nothing at all — The machine is not getting power, or it is getting power and its supply components have failed.
- Lights come on but nothing happens when start is pressed — Power is present and the machine is refusing to run. The door lock, a child lock, a delay timer or a selected programme that has already finished cover nearly all of these.
- The machine starts and stops within seconds — It has begun, checked a condition, and abandoned. That is closer to a cycle fault than a start fault, and the step it stops at is the useful evidence.
- The display lights for a moment and then goes out — The machine is powering up and dropping out again, which points at the supply or at something drawing heavily the instant the cycle is requested.
- NEAR MISS — the machine starts but stops within seconds — Something is dropping out under load rather than refusing to begin, which is the stalled-cycle shortlist and not this one.
Causes, most likely first on the ARWL line
- Supply: socket, plug, breaker or an RCD that has tripped — Ranked first here, because it is free to check, it explains every completely dead machine, and a shared socket lets a different appliance take the circuit down without anybody connecting the two events. 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 or lid interlock not latching or not reporting — Second here, because it is operated every time the machine is used and it can fail in two different ways, only one of which leaves a door that swings open.
- Door not fully closed because of laundry or an overloaded drum — Third here, because the door looks shut, the catch cannot reach, and the machine never sees a lock — which reads as an electrical fault and is put right by taking half the load out.
- Programme selector or start switch worn — Fourth here, because a selector loses one position at a time, which is why a machine that runs on some programmes and not others points here rather than at anything shared.
- Main control board or its supply — Last here: it is the least common of these and the most expensive to guess at, and because almost everything that looks like a board failure is one of these above it.
What to check first, second, third
- Prove the socket with something else — A lamp or a phone charger in the same socket settles the supply question immediately, and it is worth doing before the machine is moved or opened for any reason.
- Take half the laundry out and close the door firmly — An overloaded drum stops the door reaching its catch. It is the cheapest test on the page and it accounts for a real share of no-start calls.
- Cancel any programme and select a simple one from cold — A machine sitting in a finished or paused state ignores the start button. Cancelling properly and choosing the shortest programme rules that out in under a minute.
- Try several programmes in turn — A machine that starts on one programme and not another has a selector fault rather than a supply or control fault, and that distinction saves replacing the wrong part.
Before any panel comes off
Safety
Prove the socket with another appliance before anything is moved, and unplug this one before a panel comes off: a capacitor can hold a charge after the power is off. A machine that hums without moving is drawing current into something that cannot turn, so switch it off rather than retrying. Water and mains wiring share the lower part of the cabinet, so dry any spill before power is restored..

When to call a technician
Call at the point where the next step needs the front or the top panel off, because that line puts the filter, the hoses, the seals and the feet on your side of it and everything else on the other. Stop immediately if the machine hums without moving: leave it off rather than retrying, because that state draws current into a part that cannot do anything with it.
