In short
On the Ariston ARWDF washer line, a machine that will not start is worth working through in a set order: a control lock, a delay timer or a cycle left paused first, then water supply off, so the machine stalls before it visibly starts, 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 an owner actually sees
- A lock symbol, a delay indicator, or a programme that will not cancel — The machine is following an instruction rather than refusing one.
- The cycle appears to start and then nothing audible happens — A machine waiting on water is silent, and silence reads as a dead machine.
- NEAR MISS — it starts and then stops part way through — That is a cycle fault rather than a no-start, and the cycle page ranks those causes properly.
Causes in the order they are worth suspecting on the ARWDF line
- A control lock, a delay timer or a cycle left paused — The first thing to suspect: child locks, delay starts and paused cycles all leave a machine lit and unresponsive, and a machine that was left mid-cycle yesterday will often refuse everything until the old programme is properly cancelled.
- Water supply off, so the machine stalls before it visibly starts — Closed taps leave a machine sitting silently at its first step, which looks identical to a machine that will not start.
- No power at the socket, or a tripped breaker — A dead socket or a tripped breaker explains a dark panel completely, and both are checked in a minute.
- The door or lid is not latching and confirming — The latch is the remaining mechanical explanation when the panel is alive and nothing happens on start.
- The control board, the start switch or the motor circuit — Last here, and the only cause on this list that is not owner work — a failed start switch, a dead board or an open motor circuit needs a meter on live terminals to separate, and that is the boundary of owner work on any mains appliance.
What to check first, second and third
- Read the panel and hold the cancel control long enough to clear it — Most machines need the control held, not tapped, to clear a lock or a delay. Done first because it separates the likeliest causes before any tool is needed.
- Check both taps are fully open and listen for water entering — Second: it confirms or dismisses what the first check suggested.
- Test the socket with something else and look at the consumer unit — Third, once the two checks above are clean.
Before you start work
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. If the breaker trips the moment the machine is plugged in, leave it off: a standard US household branch circuit is 15 A or 20 A at 120 V, and protection that operates immediately is doing its job. Never defeat a door interlock to make a cycle run.

Where owner work ends
Call at once, and leave the machine unplugged, if the breaker trips as soon as it is connected or if anything smells hot. That is not a starting problem any more.
