The short answer
When the BDV line will not start, decide first whether the machine is dead or merely refusing. A dead panel means the supply — breaker, plug or cord. A lit panel that will not accept a start command means the door switch, a lock or a start switch, and those are cheaper by an order of magnitude. The name covers a small group of numbers that share their construction, which is what fixes the order of the checks below.
What you observe on these models
- Nothing at all happens — no lights, no sound — The machine is not being powered; on electric builds a half-supply fault will also do this while the breaker looks fine.
- The panel lights but the drum does not move — Power and control are alive, so the machine is refusing rather than dead — the door switch is the first suspect.
- It hums when start is pressed but the drum stays still — The motor is being energised and cannot turn — a seized part, a shed belt wrapped on the shaft, or a start winding fault.
- It starts if you hold the door firmly closed — A worn door switch making intermittently, which is a cheap part and an unambiguous diagnosis.
- NEAR MISS — it runs but never heats — That is a heating fault rather than a start fault, and it belongs on a different page.
Causes, most likely first on the BDV line
- Control lock or a delayed start — Most likely here. It is the only cause on the list with a zero-cost, zero-part cure.
- Door switch not making — Second on this family. It ranks first because it is a cheap part, a common failure, and it perfectly imitates a dead machine.
- Supply, breaker, cord or outlet — Third, and less common. A completely dead panel is a supply question until proven otherwise, and on a large-appliance circuit half the supply can be lost while the machine still looks connected.
Check in this order, and why
- Look for a lock or delay indicator and clear it — Hold the marked button for a few seconds. A delay timer set by accident explains a machine that did nothing and then ran hours later.
- Close the door deliberately and listen for the switch — It should click. Try starting while pressing the door firmly shut — if it runs then, the switch is the fault and nothing else needs testing.
- Prove power at the outlet and check both sides of the breaker — On a large-appliance circuit half the supply can be lost while the machine still shows signs of life. Check the cord where it passes behind the machine, too.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off. Never run the machine with the drum panel removed to observe a fault, and clear lint from the cabinet while you are inside it: lint against a heater is how dryer fires start.

When to call a technician
On the BDV line the line is the cabinet. Everything outside it is yours; everything inside needs a meter. If the machine hums without turning, stop pressing start — each attempt on a seized drum or a wrapped belt stresses the motor further, and it turns a belt replacement into a motor replacement.
