The short answer
Here is what the symptom means on a Black+Decker washer: a door leak on a washer is usually debris in the fold rather than a failed seal. Clearing and cleaning the fold is free and fixes most of these; a tear is a part and a hinge is service work.
What you actually see
- Water at the front of the machine during the wash step — A leak timed to the wash step points at the door rather than the fill or drain.
- The door will not latch on the first attempt — A door that needs a second push is a catch or an alignment problem.
- Black marks in the seal fold — Growth in the fold is a smell question as well as a seal one.
- The door glass is loose in its frame — A loose door assembly loads the seal unevenly.
Causes, ranked for this washer
- Debris trapped in the seal fold — Ranks first because grit, hair, coins and lint collect in the fold and hold it open a fraction, which leaks during the wash step only. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
- Seal torn or split — Second because it ranks below debris because clearing the fold is free and because a tear is obvious once the fold is opened. Confirm it before moving on, because the entries below read differently once it is ruled out.
- Detergent residue hardening on the seal — Third because residue builds into a crust that stops the rubber sitting flat, and it also holds moisture against it. Rule it in or out properly here; a maybe at this position costs an hour further down.
What to check, in order
- First — the fold of the seal — Look for a shiny worn patch where debris has been sitting. That is where a tear will start.
- Second — the seal surface — Open the fold with a thumb and look right around the circumference in good light.
Checks an owner can do safely
- Step 1. Sight the gaps at each corner — Close the door and look at the gap at each corner from the side. Unequal gaps mean the door is not sitting square.
Tools: noneAbout 5 min
- Step 2. Clear the seal fold — Pull the fold back and run a finger right around it, removing grit, hair, lint and anything else you find, then dry it.
Tools: clothAbout 15 min
- Step 3. Clean the sealing face — Wipe the face and the frame it meets with a mild cleaner and dry both thoroughly. Residue stops the rubber sitting flat.

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 fold is clean, the face is clean, the load size is right and a bead still forms at the bottom of the door — a torn seal is a part and fitting it is service work on most compact machines.

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.
