The short answer
On a BLACK+DECKER dryer, controls, display or error code most often comes down to a full-tank or clean-filter reminder. The tank and filter reminders lead on a compact ventless machine, because they are shown on the same panel as fault codes and are routinely read as failures. Most of what follows is an owner check; it becomes a service call when the code returns immediately after a full power cycle with clear airflow.
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 the cycle lights.
- Buttons that answer intermittently.
- A panel that lights and then goes dark.
- If instead you see this: A padlock symbol on the display — that is the control lock rather than a fault.
Ranked causes on a BLACK+DECKER dryer
- The tank and filter reminders lead on a compact ventless machine, because they are shown on the same panel as fault codes and are routinely read as failures. 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 full-tank or clean-filter reminder — Why: Ventless machines report a full tank and a dirty filter through the same panel, and owners read the indicator as a fault code.
- A control lock or a delay start — Why: Both leave the panel alive while the machine does nothing, and both are set by button combinations that are easy to trigger by accident.
- A marginal supply — Why: A loose plug, an extension lead or a shared circuit produces resets and dropouts that imitate a failing board precisely.
- A thermal condition the control is reporting — Why: Many dryer codes report an over-temperature or a sensor out of range, which is the control truthfully reporting restricted airflow rather than a fault in itself.
- The door switch — Why: A marginal switch makes the control see the door opening, which aborts programmes and produces codes that look random but are not.
- The touch panel or membrane — Why: One dead button with the rest working is a panel fault, which is a much smaller repair than the board behind it.
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, and note whether the machine still runs.
- Then rule out the indicators that are reports rather than faults: full tank, clean filter, control lock, delay start.
- Then power the machine down at the breaker for several minutes 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 panel showing the code or the light pattern, and note whether the drum still turns. — Number: 1 — Tools: phone camera — Time: a few minutes
- Empty the condensate tank and clear the lint filter, then see whether the indicator clears. — Number: 2 — Tools: none — Time: under ten minutes
- Look for a padlock symbol and a delay indicator, and clear both by holding the marked buttons. — Number: 3 — Tools: none — Time: a few minutes
- Switch the machine off at the breaker for several minutes, then restore power and wait a minute before pressing anything. — Number: 4 — 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 dryer 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 with clear airflow one or more buttons are permanently dead the machine aborts at the same point in every cycle

Common BLACK+DECKER Dryer Problems (black-decker-dryer-problems)
This page is generalized across the BLACK+DECKER dryer 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. Where a family- or model-specific page exists beneath this one, the links below go down to it.
