The **door** display on a Samsung washing machine points to **main door is not closed / door-lock condition**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **door**. Search normalization stores it as **DOOR** while preserving the characters a homeowner actually sees.

Quick answer
Main door is not closed / door-lock condition.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so DOOR may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **door** display on a Samsung washing machine points to **main door is not closed / door-lock condition**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **door**.

Signs
Symptoms you may notice
On affected Samsung washing machine models, the appliance can refuse to start or continue a cycle.
One clue that supports the door diagnosis is that a door, lid, divider, or latch can not be recognized as closed or locked.
door can be accompanied by this pattern: the code can return immediately when the appliance reaches a door-safety verify.
Depending on the exact model, door appears during the washer stage associated with main door is not closed / door-lock condition.
door can be accompanied by this pattern: the cycle can pause, stop, retry, drain, or refuse to advance until the condition is cleared.
Why it happens
Possible causes
varies by model — official regional/current support — Main door is not closed / door-lock condition
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With door recorded, open and close the door or lid firmly without forcing it.
To rule out an accessible cause, remove clothing, racks, cookware, packaging, or debris that can interfere with closure.
For door, start by doing this: inspect the visible latch/strike area for obstruction or damage without bypassing the safety interlock.
Before opening any service area, if water is trapped in a washer or dishwasher, resolve the drain condition before trying to force the door open.
For door, start by doing this: record the code and the cycle stage where it appears.
As an external check for door, check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. Do not bypass a safety device merely to see whether door disappears.

When to request repair service
Request service if the door closes normally but the code returns, the latch will not release safely, or diagnosis requires testing the interlock, wiring, or control circuit. If door keeps returning, record the stage at which it reappears so the technician can test the main door is not closed / door-lock condition path instead of replacing parts by guesswork.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **door** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **door**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **door** before replacing anything.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Washer door** separate from same-looking codes used by other Samsung appliance families.
