The short answer
On a BLACK+DECKER dishwasher, door, latch or seal fault most often comes down to something in the way. Obstruction and a dirty gasket lead on a compact machine, where the rack sits close to the door and a single tall item stops the door closing squarely. Most of what follows is an owner check; it becomes a service call when the door falls or slams after the obvious obstructions have been cleared.
What you are actually seeing
- The entries at the end belong to a different fault and send you elsewhere.
- The door drops open rather than staying where you leave it.
- The door slams the last part of the way down.
- A gap you can see at one corner of the closed door.
- If instead you see this: A machine that will not start at all — read the will-not-start page, because the latch is a likely cause there too.
Ranked causes on a BLACK+DECKER dishwasher
- Obstruction and a dirty gasket lead on a compact machine, where the rack sits close to the door and a single tall item stops the door closing squarely. 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.
- Something in the way — Why: A rack corner, a tall item or a handle sticking through the rack stops the door reaching the frame, which reads as a latch fault.
- A dirty gasket or sealing face — Why: Grease on the gasket stops it making contact, and it takes a wash rather than a part.
- The gasket is hard, torn or out of its channel — Why: The seal takes heat and detergent for years and eventually goes hard.
- The strike plate has drifted — Why: The plate the latch catches is adjustable on most machines, and a machine that has settled or been moved needs it reset.
What to check, and why in this order
- Free checks first, then the ones that need the machine opened.
- Watch how the door behaves when you release it at half open. A door that falls or slams has a spring or tension problem, and everything else follows from that.
- Then clear obstructions and clean the gasket and the sealing face, which between them explain a surprising share of latch and leak complaints.
- Then look at the strike plate and the latch alignment, since both are adjustable on most machines.
Checks you can safely do yourself
- Stop at the first step that would need a meter on live terminals.
- Open the door to halfway and let go. It should stay where you leave it; a door that falls or rises has a spring or cable problem. — Number: 1 — Tools: none — Time: a few minutes
- Take the lower rack out and check the door path for anything catching: rack corners, tall handles, a fallen item in the door channel. — Number: 2 — Tools: none — Time: under ten minutes
- Wash the gasket and the tub lip with warm soapy water and dry both, then close the door and look for gaps along the edge. — Number: 3 — Tools: warm soapy water, cloth — Time: under half an hour
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. A loaded dishwasher is heavier than it looks and its weight sits high; get help before moving it, empty it first, and never let a door take your weight. Do not remove a door from its hinges while the door is loaded, and never defeat a door switch to keep something running with the door open.
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 door falls or slams after the obvious obstructions have been cleared the door is visibly out of parallel with the machine face a custom or decorative panel has been fitted and the door no longer balances

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.
