The short answer
Here is what the symptom means on a Black+Decker washer: a trip is usually a shared circuit rather than a broken machine, but a tingle never is. Testing on a dedicated socket is free and settles most of it. Anything past that is a stop-and-call finding.
What you actually see
- The machine trips the breaker or the outlet protection — A trip is the protection working and it ends owner diagnosis.
- The plug or socket is warm after a cycle — A warm plug is a poor connection making heat and it gets worse.
- It trips only during the spin — A trip at one step points at the load drawn at that step.
- The machine runs but the lights in the room dim — Dimming under load points at the circuit rather than the appliance.
Causes, ranked for this washer
- Shared or overloaded circuit — Ranks first because a washer is a heavy intermittent load, and a socket shared with a kettle, a heater or a dryer trips on the combination rather than on a fault. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
- Damaged cord or plug — Second because it produces intermittent tripping that follows movement rather than the cycle, which is a distinctive pattern. Confirm it before moving on, because the entries below read differently once it is ruled out.
- Water where it should not be — Third because a leak that reaches the base plate or the outlet turns a plumbing problem into an electrical one, and the protection will respond. Rule it in or out properly here; a maybe at this position costs an hour further down.
What to check, in order
- First — the circuit the machine is on — Note what else was running each time it tripped. That correlation is usually the whole diagnosis.
- Second — the cord and plug — Unplug the machine and run the cord through your hand from plug to cabinet, feeling for flats and nicks.
Checks an owner can do safely
- Step 1. Stop at any smell or tingle — A burning smell or any sensation from the cabinet means unplugging the machine and not using it again until it is tested.
Tools: noneAbout 1 min
- Step 2. Isolate the circuit and leave it isolated — At the first trip, tingle or burning smell, switch off at the breaker and unplug the machine. Nothing else here happens with it live.
Tools: noneAbout 1 min
- Step 3. Inspect the cord and plug — With the machine unplugged, run the cord through your hand end to end and check the pins for browning or pitting.
Tools: noneAbout 10 min

Safety
Shut off, unplug, dry off — in that order. A capacitor can hold a charge after the power is off. Kneeling on a wet floor beside a plugged-in appliance is the one mistake on this page that has consequences beyond the repair.
When this becomes a service call
Where the owner side ends is easy to state. Call when the machine trips a circuit with nothing else on it. That is a genuine fault and it needs a meter on an isolated machine.

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.
