What Does Error Code dEi Mean on a Samsung Washing Machine?
Push the door firmly shut until you hear a click, then restart the cycle — if the latch was simply not fully engaged, this clears the error immediately (takes about 2 minutes).
Fault description
When your Samsung washing machine displays the dEi error code, it is telling you that the door is not registering as securely closed. The machine's control board monitors the door lock assembly throughout the wash cycle, and if it cannot confirm a locked position, it will stop the programme and show this code to prevent water leaking into your home.
In practical terms, you may notice the drum refusing to spin up, the cycle failing to start at all, or the machine pausing mid-wash and displaying dEi on the screen. The door itself may feel closed to the touch, but the internal latch or lock mechanism is not completing the electrical circuit that signals a safe, sealed door.
The good news is that this fault is often straightforward to diagnose and, in many cases, you can resolve it without calling anyone out. Working through the steps below in order will help you identify whether the issue is a simple alignment problem or a component that needs replacing.
Causes
- Door not fully closed — The most common reason for dEi is simply that the door has not been pushed firmly enough to engage the latch. Laundry caught in the door seal or an overfilled drum can prevent the door from closing completely.
- Dirty or obstructed door latch — Detergent residue, limescale, and fabric fibres can build up on the latch tab and the strike plate inside the door aperture. This build-up stops the latch from retracting and seating correctly, so the lock cannot engage.
- Worn or broken latch tab — The plastic latch tab on the door handle assembly can crack or wear down over time, especially with heavy daily use. If the tab no longer protrudes far enough, it will not trigger the lock mechanism even when the door appears shut.
- Faulty door lock assembly — The door lock, also called the door interlock, contains a small solenoid and electrical contacts that physically secure the door and send a confirmation signal to the control board. If the solenoid or contacts fail, the board never receives that signal and throws the dEi code.
- Door hinge misalignment — Over time, the door hinge can loosen or bend slightly, causing the door to sit at a slight angle. Even a small amount of misalignment can mean the latch tab misses the strike plate, preventing proper engagement.
- Wiring fault between door lock and control board — The wiring harness connecting the door lock assembly to the main control board can develop a loose connector or a broken wire, particularly near the hinge where the cable flexes repeatedly. This interrupts the signal even if the lock itself is working correctly.
Step-by-Step Fix
- 1
Check for laundry caught in the door seal
Open the door and inspect the rubber door gasket all the way around. Pull out any clothing or fabric that is sitting between the seal and the drum rim. Overfilling is a frequent culprit — if the drum is packed tightly, remove a few items, then close the door firmly and try restarting the cycle.

Push the door firmly shut and listen for a click
Stand directly in front of the machine and push the door closed with a firm, even pressure until you hear or feel a distinct click. Avoid pushing at an angle. If the error clears and the cycle starts, the latch simply was not fully engaged. If the error returns, continue to the next step.

Clean the door latch and strike plate
Mix a small amount of warm water with white vinegar or a mild detergent. Using an old toothbrush, scrub the latch tab on the door and the corresponding strike plate recess on the machine body. Rinse with a damp cloth and dry thoroughly. Residue build-up here is surprisingly common and can prevent a clean engagement.

Inspect the latch tab for damage
With the door open, look closely at the plastic latch tab that protrudes from the door handle assembly. Press it gently with your finger — it should spring back firmly. If it feels loose, does not spring back, or you can see cracks or chips, the door handle and latch assembly will need to be replaced.
- 5
Check the door hinge for looseness or misalignment
Open the door fully and grip it near the hinge side, gently testing for any wobble or play. Tighten any visible hinge screws with a suitable screwdriver. Close the door slowly and watch whether the latch tab lines up cleanly with the strike plate — if it is visibly off-centre, the hinge may need adjustment or replacement.

Test the door lock assembly
If all the above checks pass but the error persists, the door lock interlock itself is the likely culprit. Unplug the machine from the mains before proceeding. Access the door lock by removing the door seal and the front panel screws as described in your model's service guide. Check the wiring connector to the lock for corrosion or loose pins, and reseat it firmly. If the connector looks sound, the lock unit itself will need replacing.

Reset the machine after any repair
Once you have made a repair or adjustment, plug the machine back in, select a short cycle, and press Start. Watch the door lock indicator and listen for the lock engaging within the first few seconds. If the dEi code does not reappear and the cycle runs through, the fault has been resolved.

When to call a service technician
If you have cleaned the latch, confirmed the door aligns correctly, and replaced the door lock assembly but the dEi error still appears, the fault is likely in the main control board or the wiring harness running to it. Diagnosing a PCB fault or tracing a broken wire through the machine's internal routing requires specialist test equipment and experience — attempting it without the right tools risks causing further damage.
You should also contact a service technician if the door lock becomes physically jammed and the door will not open at all, or if you notice any signs of burning, melting, or a burning smell near the door lock area, as these indicate an electrical fault that should not be handled without professional assessment.

Frequently Asked Questions
Can I use my washing machine while it is showing the dEi error?
No. The machine will not start or continue a cycle when dEi is displayed because it cannot confirm the door is safely locked. Running a wash with an unsecured door would risk water escaping into your home. Resolve the fault before attempting to use the appliance.
Will turning the machine off and on again clear the dEi error?
A power cycle alone will not fix dEi if there is a physical problem with the door or lock. The error will return as soon as the machine checks the door status again. Power cycling is only useful after you have already addressed the underlying cause, such as repositioning laundry or cleaning the latch.
How do I open the door if it is stuck locked with dEi showing?
Most Samsung washing machines have an emergency door release cord located behind the kick panel at the bottom front of the machine. Remove the panel, locate the small coloured pull tab or cord, and pull it firmly downward. This manually releases the door lock. Always unplug the machine before doing this if there is any water in the drum.
Is the dEi error the same as the dE or dE1 error on Samsung machines?
They are closely related. All three codes point to a door detection or locking problem, and the troubleshooting steps are essentially the same. The specific code displayed can vary depending on the model and firmware version, but the door lock assembly and latch are the components to investigate in every case.
How long does a door lock assembly replacement take?
For most Samsung front-loader models, replacing the door lock interlock takes between 30 and 60 minutes if you are comfortable with basic appliance repair. You will need to remove the door seal and part of the front panel to access the lock. If you are not confident working inside the machine, a service technician can usually complete the job in a single visit.
