The short answer
On a Black+Decker washer, a control that forgets is being interrupted, and the interruption is usually outside the machine. Moving to a dedicated socket is the whole test and it costs nothing.
What you actually see
- Programme selection does nothing — A dial or button that changes nothing separates the input from the control.
- The cycle time jumps or counts unevenly — An uneven countdown is normal on machines that adapt the cycle to the load.
- The machine ignores a temperature setting — A machine on a cold-only supply cannot reach a warm setting whatever the panel says.
- The display is dark but the machine still runs — A dead display over a working machine is a display fault.
Causes, ranked for this washer
- Supply sagging under load — Most likely — a control resets when the machine draws hard on a marginal circuit, and a portable washer is often on a kitchen socket shared with something heavy. A clean result here does not just remove one part; it removes everything that depends on it.
- Control left in a stuck state — Common — it resolves a large share of odd panel behaviour, which is why it comes first regardless of how the fault presents. It is worth being sure about this one rather than half-sure, since everything after it assumes a verdict.
- Water not arriving so the machine waits — Regular — a machine that cannot fill waits, times out and shows a code, which owners read as a control fault rather than a supply one. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
What to check, in order
- First — the outlet and the circuit — Note what else was running each time it reset. That correlation is the diagnosis.
- Second — a full power cycle — Unplug the machine for several minutes until any display is fully dark, then restore power and watch the start-up.
Checks an owner can do safely
- Step 1. Clear any lock or delay — Hold each button for several seconds in turn, cancel any programme, and set a short cycle explicitly.
Tools: noneAbout 10 min
- Step 2. Test every button — Press each in turn and note which respond and which produce the wrong result. The pattern names the part.
Tools: pen and paperAbout 10 min
- Step 3. Record the exact code — Write down the characters shown, at which point in the cycle they appeared, and what the machine was doing.

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, so treat a stored charge as live even when the cord is in your hand. Do not run the machine with a panel off to watch what happens, and do not defeat any switch that cuts power when a door opens.
When this becomes a service call
Where the owner side ends is easy to state. A code that appears at the same point in every cycle is reporting a specific step failing, and that step is usually more informative than the code itself.

This page is written for Black+Decker washers in general. It does not cover a specific family, a specific model number or a control board revision, and where a family or model page exists it will be more precise than this one — start here to understand the fault, then follow the more specific page for the part numbers and the board layout.
