The short answer
On a Costway washing machine that is not starting, the cause to suspect first is door or lid lock not reporting closed, with power at the socket, breaker or protective device behind it. The ranking below is written for the front-load build, which you can confirm in seconds: a horizontal door with a boot seal means a door lock that has to report closed before anything at all happens. The door, the taps, the breaker and the load are owner work; the pump, the motor and the board are not.
What you observe
- Water still standing in the drum — Most machines refuse to start over it, so the drain is the real fault.
- Panel lights and the cycle never begins — Power is present, so the question is the lock, the water or a lock setting.
- Completely dead with no lights — A supply question: the socket, the breaker or a protective device.
- A hum with no drum movement — Power present and rotation absent, which is the motor circuit.
- It stopped mid-cycle and now ignores the button — Usually an imbalance pause rather than a fault.
- NEAR MISS — it starts and then stops without filling — That is a fill fault rather than a start fault, and the taps are the first thing to check.
Causes, most likely first on this brand
- Door or lid lock not reporting closed — Ranked first here: it ranks first on a front-load machine because the lock is in the start path of every single cycle and because the click it makes is a free diagnosis.
- Power at the socket, breaker or protective device — Second: a tripped breaker or protective device leaves the machine dead with nothing wrong inside it.
- Standing water the machine will not start over — Third: it ranks high on a front-load machine because the lock will not release either, which makes the machine feel completely inert.
- Control board or start switch — Fourth: it sits here because a board fault usually shows as inconsistent behaviour rather than a clean refusal.
- Drive motor or its start circuit — Fifth: a hum with a drum that does not move is power present and rotation absent, which is the motor circuit rather than the controls.
- Taps closed or hoses kinked — Sixth: a machine that cannot fill sits waiting rather than reporting an error, which looks exactly like a machine that will not start.
Check in this order, and why
- Close the door or lid firmly and listen for the lock — It is in the start path of every cycle, so the click is a free diagnosis.
- Check the socket, the breaker and any protective device — A tripped device leaves the machine dead with nothing wrong inside it.
- Look for water still standing in the drum — Most machines will not begin over standing water, so this reads as a start fault.
- Note whether the panel responds at all — Inconsistent behaviour points at the board; a clean refusal usually does not.
What an owner can safely check
- Open the door, redistribute the load and try again — A machine paused on an imbalance restarts once the load is spread.
About 10 min
- Look for a delay-start or control-lock indicator and clear it — Free, and easy to set while wiping the panel down.
About 5 min
- Close the door or lid firmly and listen for the lock to engage — In the start path of every cycle and free to test.
About 5 min
- STOP HERE if water is standing and will not drain — That is a drain fault, and the filter and pump sit behind the lower panel.
Before you open anything
Safety
Power off at the wall, water off at the taps, then open the machine. Both come first because the wiring and the water share the cabinet. Never force the door on a drum with water in it: drain through the filter with a shallow tray first. Moving the machine is a two-person job, and it should be empty before it moves at all.
When to call a technician
Once the free checks are clean the remaining causes are few and a visit is short. Turn the machine off at the wall while you wait if it has hummed or tripped anything, rather than leaving it powered and trying again later.

What this page does not cover
Written for Costway washing machines as a class, not for one family. Family-level pages sit beneath it — EP, FP, XQB — and where your model is named on one of those, that page is the more specific answer. Wiring colours, torque figures and part numbers are deliberately not here: they differ by family.
