The short answer
Here is what the symptom means on a Black+Decker washer: a portable washer that does nothing is usually reporting a dead socket, an unlatched lid or a closed tap. All three are free to check and cover most of these; the motor and the control are where a technician takes over.
What you actually see
- Nothing at all when the button is pressed — No light, no sound and no display is a supply picture.
- It hums without moving the drum — A hum with no movement is a motor being asked to turn against something.
- It starts only when the lid is pressed down — A start that depends on lid pressure convicts the lid switch.
- It beeps and refuses — A beep with no cycle means the control heard you and something else refused.
Causes, ranked for this washer
- No power at the outlet — Ranks first because it is first because it is free to test and because a switched socket, a tripped device or a dead extension lead explain a large share of these. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
- Lid or door not closing its switch — Second because it produces a total refusal on a machine that is otherwise healthy, which makes it the highest-value free check here. Confirm it before moving on, because the entries below read differently once it is ruled out.
- Water supply not turned on — Third because a machine that cannot fill will not start its cycle, and on a portable washer the tap is turned off between loads by design. Rule it in or out properly here; a maybe at this position costs an hour further down.
What to check, in order
- First — the outlet itself — Check the breaker and any protection device on that run. A standard household branch circuit is 15 or 20 amps.
- Second — the lid catch and switch — Close the lid and listen for a definite click, then press it down and try again. A start under pressure convicts the switch.
Checks an owner can do safely
- Step 1. Turn the drum by hand — With the machine unplugged, turn the drum. A drum that will not move, or one with no resistance at all, points at the mechanical side.
Tools: noneAbout 5 min
- Step 2. Test the outlet with something else — Plug a lamp or a charger into the same socket. A dead socket means the machine is not the fault.
Tools: lamp or phone chargerAbout 5 min
- Step 3. Close the lid firmly and listen — Press the lid properly shut, listen for a definite click, and try to start. A start under pressure convicts the switch.

Safety
Take the power away before the panel. Unplug the appliance or open its breaker; a capacitor can hold a charge after the power is off, so a dead-looking board is not a safe board. Work with dry hands on a dry floor and put the panel back before power goes on.
When this becomes a service call
Where the owner side ends is easy to state. Call when the socket is live, the lid latches, the tap is open and a proper power cycle changes nothing — the motor, the belt and the control all need the cabinet open.

What this page does not cover
One limitation worth stating up front: this page is written for the Black+Decker washer range rather than for your particular unit. It does not name families, model numbers or control revisions. Where a page exists that does, it is more precise than this one and it is linked under Related pages.
