The short answer
On this platform the machine is usually refusing rather than failing. Work through the conditions it needs before you go near the electrics: vend satisfied, doors closed, lock engaged, control not in a service mode. Only then is power worth suspecting.
What you actually see and hear
- The display is lit but nothing happens when a cycle is selected — The machine is powered and is declining. That is logic, not electrics.
- Completely dark, no lights and no tones — Now power is worth suspecting - supply, breaker, or the machine's own protection.
- It accepts the selection, clicks, then returns to idle — The lock is trying and failing to engage, which is a mechanical fault with an electrical face.
- It starts only when the service door is pressed shut — A switch that needs help is a switch that will strand a customer tomorrow.
- NEAR MISS - it starts and then stops part-way — That is a cycle fault, not a start fault, and it is a different page.
Causes, most likely first on this machine
- Vend not satisfied or vend hardware faulty — First on a vended machine. A jammed coin mechanism, a card reader that has lost its link, or a price that was changed will hold the machine at idle with the display perfectly healthy.
- Door, lid or service-door switch not made — Second. These are the hardest-worked switches in the room and they wear out in the closed position long before they break.
- Lid or door lock not engaging — Third. The lock tries, fails and hands the cycle back, which reads as a refusal rather than as a fault.
- Control in a service, manager or diagnostic mode — Fourth. A machine left in a programming mode after service is inert to a customer and looks broken.
- Supply, breaker or a machine protection device — Last unless the machine is completely dark, in which case it moves straight to first.
Check in this order, and why
- Look at the display before anything else — Lit means power is present and the ranking above applies. Dark means start at the breaker.
- Satisfy the vend and watch what changes — A machine that lights a cycle but never starts it is usually still waiting for payment.
- Close and hold the service door, then try again — Isolates a worn switch in seconds without any tools.
- Listen for the lock at the start of a cycle — A click followed by nothing is a lock that is not making its switch.
What an owner can safely check
- Check the breaker and, if the machine is dark, that the outlet or connection is live — A standard household branch circuit is fifteen or twenty amps; a large machine may be on its own higher-rated circuit.
About 10 min
- Satisfy the vend in the normal way and observe — Separates payment logic from the machine in one attempt.
About 10 min
- Press the service door fully closed and start a cycle — A cycle that starts only with pressure has named its own fault.
About 10 min
- Close the lid or door firmly and listen for the lock — A healthy lock is audible and immediate.
About 5 min
- STOP HERE before opening the control housing or testing live terminals — Vended controls are service work and often need the programming key.
Before you open anything
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 machine is completely dark, treat it as live until you have switched off its breaker yourself - a machine that does not respond is not the same as a machine that is not powered. Never bypass the lid or door interlock to make a cycle start.
When to call a technician
Call when the display is lit, the vend is satisfied, the doors are closed and the lock still will not engage: that is a switch, a lock or a control, and on a vended machine those are service parts. Call the card or coin supplier rather than an appliance technician if the machine refuses only at the payment step, because that hardware is usually maintained separately. Call immediately if the machine is dark and its breaker trips again when reset, since a repeat trip is a fault to the ground and not a nuisance.

What this page does not cover
This page is written for the Alliance-built commercial washer class, not for one family or model line. Where a vended or on-premise page exists for your unit it is the more specific answer and it is linked above, so go there first if your machine is named. What is deliberately not here: vend parameters, coin and card interface details, switch part numbers and service-mode key sequences, all of which differ by family and belong on the page for that family.
