The short answer
If the panel is dark, the fault is in the supply rather than the washer. If the panel lights but the cycle never begins, the machine is waiting for the door lock to confirm or for water it cannot get. Both are owner checks, and a control board is the least likely of the five causes below.
What you observe
- The display is completely dark — Nothing lights when you press the power button.
- Lights come on, a cycle is selected, nothing happens — No lock click, no fill, no drum movement.
- The lock clicks, it tries, then stops and unlocks — It attempted the cycle and failed a condition it needs.
- It starts only if you hold the door shut — A clear pointer at the latch rather than anything electronic.
- NEAR MISS - it starts but sits silent before filling — Many programmes weigh the load first. Silence is not failure if the cycle runs.
Causes, most likely first on this brand
- No power at the outlet — First, because compact washers so often share a closet circuit with a dryer or a light. A tripped breaker or residual current device is the commonest reason a panel is dark, and it costs nothing to check.
- A door lock that will not confirm — Second, and the commonest cause when the panel is lit. The machine tests the latch before committing; a worn catch or a door held proud by a tight frame means it never gets confirmation.
- Closed or restricted taps — Third. A machine that cannot fill will start and then abandon the cycle. Taps get closed for a repair and never reopened, and inlet screens silt up over years.
- A control lock or delay start left set — Fourth, and worth ruling out before any repair. Both look exactly like a dead machine from the front panel.
- A failed control board or wiring fault — Last. Least likely, and the only one that is not an owner check. Everything above imitates it.
Check in this order, and why
- Decide whether the panel lights at all — That one question splits this list in half.
- Plug something else into the same outlet — Rules the supply in or out in a minute, with no tools.
- Press the door firmly shut and start again — If it now runs, the latch is the fault and the electronics are fine.
- Open both taps fully and look for a fill — A machine that starts filling was never broken, only thirsty.
What an owner can safely check
- Test the outlet with another appliance — A lamp or a charger is enough. Reset the breaker once, and once only.
About 10 min
- Close and reopen the door, then start a short cycle — Push the door in at the latch as you press start. If it only runs this way, it needs a latch.
About 10 min
- Open the taps and clean the inlet screens — Close the taps, unscrew the fill hoses at the machine, and rinse the screens in the inlet ports.
Tools: adjustable wrench, brushAbout 25 min
- Clear any delay start or control lock — Hold the labelled button until the indicator clears, then reselect the programme.
About 5 min
- STOP HERE if the panel stays dark on a good outlet — A dead machine on a live outlet is an internal supply fault.
Before you open anything
Safety
Unplug the washer before removing any panel or unscrewing a fill hose at the machine end - a capacitor can hold a charge after the power is off, and the hoses stay under mains pressure until the taps are closed. Reset a tripped breaker once; if it trips again with the washer plugged in, leave it off. Never tape the door lock to persuade the machine to start, because that interlock keeps the door shut during a high-speed spin.
When to call a technician
Call when the outlet is proven good and the panel is still dark, or when the panel lights and the machine refuses to run with the door held firmly shut and both taps open. Call without further testing if it trips the breaker the moment it is plugged in, or if you smell hot insulation: that is a short circuit, and repeated resets make it worse rather than better.
