Direct answer: A Samsung washer door usually stays locked because the cycle has not fully ended, water is still sitting in the tub, or the washer door latch is not releasing. Start by checking for standing water and a paused or interrupted cycle before you assume the latch itself is bad.
Most likely: The most common real-world cause is a drain problem that leaves water in the tub, so the washer keeps the door locked on purpose.
When this happens, the first job is to separate a normal safety lock from a true latch failure. If the tub still has water, the machine is humming like it's trying to drain, or the cycle never really finished, chase the drain path first. If the tub is empty and the lock never clicks open after power cycling, the washer door latch moves to the top of the list. Reality check: many 'bad latch' calls end up being a no-drain issue. Common wrong move: yanking the door harder when the lock is still engaged.
Don’t start with: Don't start by prying on the door handle or ordering a control board. Forced opening often breaks the strike or latch and turns one problem into two.
Clothes are wet, you can see water below the basket, or you hear sloshing when you push the drum.
Start here: Start with the drain check. The washer will usually keep the door locked until it senses the water is gone.
The cycle appears finished, there is no standing water, but the lock never clicks open.
Start here: Start with a full power reset and then focus on the washer door latch and strike area.
The machine stopped mid-cycle after a power blink, cancel, or error, and the door never released.
Start here: Give the washer time to clear the lock, then reset power and try a drain or spin cycle before touching parts.
The door feels mechanically stuck, or you hear a weak click without the door opening.
Start here: Inspect the latch area for a misaligned door, damaged strike, or latch that is not retracting.
This is the most common reason the washer keeps the door locked. If the control thinks water is still inside, it will not release the door.
Quick check: Look through the glass for water at the bottom of the tub and listen for a drain pump hum or repeated drain attempts.
A washer that was paused, canceled, or hit by a brief power loss can hold the lock longer than expected until the control resets.
Quick check: Unplug the washer for a few minutes, restore power, and try Drain/Spin or Power then Start/Pause once.
If the tub is empty and the lock light stays on or you hear a weak click with no release, the latch may be sticking or electrically failed.
Quick check: Close the door firmly and listen for a solid lock and unlock click. A weak, repeated, or absent click points toward the latch.
A sagging door, loose hinge, or damaged strike can keep the latch from releasing cleanly even when the cycle is done.
Quick check: Lift gently on the open-side edge of the door and look for rubbing, looseness, or a strike that does not line up cleanly with the latch opening.
You want to separate a normal safety lock from a failed part before you take anything apart.
Next move: If the door unlocks after the cycle fully ends or after the water clears, you likely had a temporary delay or drain issue rather than a bad latch. If the tub is empty and the door still will not release, move to a power reset. If water is still inside, go straight toward the drain branch.
What to conclude: A locked door with water inside usually means the washer is protecting against a spill. A locked door with an empty tub points more toward the latch, strike, or control not resetting.
A stuck control state is common after a canceled cycle, brief outage, or interrupted wash.
Next move: If the washer drains and then unlocks, the problem was likely a hung cycle or temporary control glitch. If it will not drain, keeps humming, or the door stays locked with water inside, inspect the drain path next. If the tub is empty and the lock light stays on, focus on the latch branch.
What to conclude: A successful reset points away from a failed part. A washer that still cannot clear water usually has a drain restriction or drain pump problem. A washer that stays locked with an empty tub leans toward the door latch.
On these calls, the locked door is often just the symptom. The real problem is that the washer never finished draining.
Next move: If the washer drains strongly and the door unlocks, the lock was doing its job and the drain restriction was the real fault. If the pump only hums, drains very weakly, or will not move water after the path is clear, the washer drain pump is the likely failed part.
Once water is out of the picture, the next most likely cause is a latch that is stuck, weak, or not lining up with the door strike.
Next move: If reseating the door or correcting a minor alignment issue lets it unlock normally, you likely avoided a parts swap. If the strike is intact but the lock stays engaged or never clicks properly, replace the washer door latch assembly. If the strike is broken or worn, replace the washer door strike.
By this point you should know whether the washer is staying locked because it cannot drain, because the latch is not releasing, or because the problem is deeper than a simple homeowner repair.
A good result: If the washer completes a cycle, drains fully, and the door unlocks within the normal delay, the repair is done.
If not: If a confirmed pump or latch replacement does not change the symptom, the problem may be in wiring or the control, which is not a smart guess-and-buy repair.
What to conclude: A clean fix here usually comes from the drain pump, the door latch, or the door strike. If those clues are not lining up, deeper electrical diagnosis is the next step.

Most often, the washer still thinks water is in the tub or the cycle did not fully clear. Give it a couple of minutes, then try a full power reset. If the tub is empty and it still will not unlock, the washer door latch is a strong suspect.
Yes. That is one of the most common reasons. If water is still inside, the washer usually keeps the door locked to prevent a spill onto the floor.
Not a good idea. Forced opening often breaks the washer door strike, handle, or latch housing. Drain the water first and reset power before trying anything mechanical.
If there is standing water or sloshing in the tub, think drain pump or blockage first. If the tub is empty and the lock light stays on or the latch clicks weakly and never releases, think washer door latch.
That usually means the problem is not fully gone. A partial drain issue, sticky latch, or failing strike can act up intermittently before it quits for good. Watch whether the tub is draining completely and whether the latch sounds strong and consistent.
Not first. On this symptom, a drain problem or washer door latch failure is far more common than a bad board. Rule those out before spending money on electronics.
