The short answer
On a BLACK+DECKER dishwasher, controls, display or error code most often comes down to a marginal electrical supply. Supply leads on a portable or countertop machine, because the cord is plugged and unplugged constantly and often shares an outlet with everything else on the worktop. Most of what follows is an owner check; it becomes a service call when the code returns immediately after a full power cycle at the breaker.
What you are actually seeing
- The entries at the end belong to a different fault and send you elsewhere.
- A code shown on the display or flashed by a cycle light.
- Buttons that answer intermittently or not at all.
- A cycle that starts on its own or changes programme mid-run.
- If instead you see this: A padlock symbol showing — that is the control lock, held on a button rather than a fault.
Ranked causes on a BLACK+DECKER dishwasher
- Supply leads on a portable or countertop machine, because the cord is plugged and unplugged constantly and often shares an outlet with everything else on the worktop. Settle one observable question before you use this ranking — countertop or portable versus built-in: a faucet quick-connect or an internal reservoir, draining into the sink or an on-board tank, means countertop or portable, while a plumbed and hard-wired unit is built-in. Look at where the water and the exhaust go. A countertop or portable unit connects to a faucet with a quick-connect adapter or fills from an internal reservoir, and it drains into the sink or into an on-board tank. A built-in unit is plumbed and hard-wired in place. On countertop or portable units, the hookup is made and broken every use, so hookup faults dominate and cost nothing to fix; on built-in units, the hookup is fixed, so a fault that appears after months of good service is far more likely to be inside the machine.
- A marginal electrical supply — Why: A loose outlet or a shared circuit produces resets and dropouts that look exactly like a failing board.
- Control lock or a delay timer — Why: Both leave the panel alive and answering while the machine does nothing, and both are set by a button combination that a wiping cloth can find.
- A latched fault from the previous cycle — Why: Controls hold a fault state until they are properly cleared, so a code can survive long after the condition that caused it has gone.
- A drain or fill condition the control is reporting — Why: A large share of dishwasher codes are the control truthfully reporting that water did not arrive or did not leave in the time it expected. The control is fine.
- The door switch — Why: A marginal switch makes the control see the door opening mid-cycle, which produces aborted programmes, beeping and codes that seem random.
What to check, and why in this order
- Free checks first, then the ones that need the machine opened.
- Write down the exact code or light pattern before touching anything, including whether there is water in the tub. A code with water in the tub is nearly always a drain report.
- Clear the two settings that imitate a fault: the control lock and a delay start.
- Then power the machine down at the breaker for several minutes to clear a latched state, and see whether the code returns.
Checks you can safely do yourself
- Stop at the first step that would need a meter on live terminals.
- Photograph the display or the flashing light pattern, and note whether there is water standing in the tub. — Number: 1 — Tools: phone camera — Time: a few minutes
- Look for a padlock symbol and a delay indicator, and clear both by holding the marked buttons. — Number: 2 — Tools: none — Time: a few minutes
- Switch the machine off at the breaker or the wall switch for several minutes, then restore power without pressing anything for a minute. — Number: 3 — Tools: none — Time: under ten minutes
Before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Nothing below asks you to put a meter on live terminals, and nothing below asks you to defeat a door switch or an interlock — those exist to cut power to something that would otherwise hurt you. If the plug, the cord or the outlet is warm, discoloured or smells hot, stop there and have the circuit looked at before you use the dishwasher again.
When to stop and call a technician
The line is whether the next step needs live testing, sealed-system access or a part you cannot verify. Call for anything behind the cabinet skin, and any repair whose part cost approaches what the appliance is worth, or when:
the code returns immediately after a full power cycle at the breaker the machine aborts at the same point in every cycle one or more buttons are permanently dead

Common BLACK+DECKER Dishwasher Problems (black-decker-dishwasher-problems)
This page is generalized across the BLACK+DECKER dishwasher range: it is written for the brand and the fault, not for one family or one model number. It carries no model-specific code table, wiring detail or part number, and no measured failure rate, because no measured snapshot was available here.
