The short answer
On the BLH family a no-start splits at once into dead panel and live panel. That split is the whole diagnostic and it is where this page differs from the brand-generic article, which treats a no-start as a single fault.
What you observe
- Panel lights but the drum will not turn — The control has power and something in the start chain is open, usually the door switch.
- A hum with no rotation — The motor is being called and cannot turn, which points at a seized blower or a jammed drum.
- It starts only if the door is pressed hard — A door switch that no longer makes reliably, and it will fail completely soon.
- Nothing at all: no panel, no click — A supply question. On a two-leg machine, losing both legs leaves this.
- NEAR MISS - it runs but stays cold — That is a heating fault and belongs on the heating page.
Causes, most likely first on BLH
- No supply at the appliance — Ranked first on the BLH family: a large appliance circuit is typically 30 A or higher at 240 V, and a double breaker can drop one leg while still looking set. What decides the order here is the protection chain, and on this family that chain is common to every model listed. This moves above door switch worn or not making, which leads the brand-generic order, because this family is a single build with fixed access points.
- Door switch worn or not making — Second: the door switch is operated at every single load, so on a machine of any age it is the likeliest thing to have failed when the panel is alive and the drum is still.
- Start switch or the control — Third: worth proving once the interlocks are clean, but a start switch that has genuinely failed is a rarer find than the two causes above it.
- Thermal fuse open in the start circuit — Fourth: the one-shot device that protects the heat sits in the motor circuit too, so a machine that overheated last week can be completely dead this week.
- Seized motor or a jammed drum — Last: last, and the hum without rotation is its signature; turning the drum by hand with the power off settles it in seconds.
Check in this order, and why
- Try the breaker and confirm the panel behaves at all — One observation splits the fault: dead panel is supply, live panel is interlock or start circuit.
- Open and close the door firmly and listen for the switch — A clear click that is now soft or absent names the door switch without any tools.
- Cut power at the breaker for a minute and retry — It clears a latched control state and takes nothing apart.
- Consider the history: did it stop heating first? — A no-heat that became a no-start points at the one-shot protection in the start circuit.
Before you open anything
Safety
Kill the power before opening anything, and run the machine only with its panels fitted and its duct connected to the outside. The drum, the blower and the heater all move or get hot.
When to call a technician
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Breaker, door and drum are owner checks. Call when the supply is proven and the door switch clicks but the machine still will not run.
