The answer first
Most dead washers are refusing rather than failing. Here the ranking starts with control lock, delayed start or a programme not confirmed. Work the door, the taps, the supply and the controls first — between them they account for almost every machine that will not begin a cycle.
What you observe
- The panel is completely dark — No power reaching the machine: the socket, the plug or the breaker.
- The panel lights but start does nothing — The machine has power and is declining to begin.
- You hear the door lock click and then nothing — It locked and then stopped, which points at the fill.
- NEAR MISS — it starts but leaves the drum full at the end — That is drainage, and the machine started perfectly well.
Causes, most likely first on a Simplex washer
- Control lock, delayed start or a programme not confirmed — A long press sets a child lock on most machines, and the indicator is easy to miss. Ranked first on a Simplex washer: a lit panel that refuses is usually locked or waiting rather than broken.
- Socket, plug or breaker — A GFCI tripped by something else on the circuit leaves the washer dead with no clue at all.
- Door or lid not locking — A washer will not run until the interlock confirms the door, and a worn strike or a packed drum stops it.
- Taps closed, or a blocked inlet screen — The inlet screens silt up over years, which starves the fill without anything failing.
- Door lock switch, wiring or the control board — Both are behind a panel and neither is owner work.
Check in this order, and why
- Look for a lock or delay indicator, then cancel and reselect the programme — Small indicators on a busy panel are easy to overlook.
- Plug something else into the socket and check the breaker — Look for a tripped GFCI on the laundry circuit.
- Close the door firmly and listen for the lock to click — No click means the machine has no reason to start.
What an owner can safely check
- Hold the lock key for several seconds, then cancel, reselect the programme and press start again — That clears a control lock and a delayed start, which between them explain most silent refusals.
About 10 min
- Plug the machine into a socket you have proved live, with no extension lead, and reset any GFCI — A standard US household branch circuit is 15 A or 20 A at 120 V, and a washer should not share one with much.
About 10 min
- STOP HERE if the next step needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
Before you open anything
Safety
Power off at the wall and close the taps before opening anything. A capacitor can hold a charge after the power is off, and the filter will hand you several litres of water if you are not ready for it. Never bypass a lid switch or a door interlock, never force a locked door on a full drum, and never move a loaded or flooded machine — drain it first.
When to call a technician
Owner work here is the socket, the door, the load, the taps and the control lock. The door lock assembly, the wiring and the control board are a technician's job. Age is the deciding factor: if the machine is old enough that the control board is the suspect, price the board against a replacement machine before agreeing to the work.

What this page does not cover
This is the generalised Simplex washer page. A family- or model-specific page, where one exists, is linked above and is the more precise answer for your unit. Left out on purpose: part numbers, connector colours, the order panels come off in, and every torque figure — a generalised page cannot be right about any of them.
