Samsung Dishwasher Won’t Latch — What’s Happening
When a Samsung dishwasher won’t latch, the sensor cannot detect that the door is closed, so the unit will not start or will show a door-related error or blinking indicator. This is not usually a formal Samsung fault code by itself, but it means the door-closed system is not being satisfied.
Samsung says a door may not close completely because the racks are not pushed in, dishes are obstructing the door, the dishwasher is not leveled, or the latch is not in the correct position. On non-display models, blinking lights can also indicate a stuck button rather than a latch fault, so the symptom should not be assumed to be mechanical without checking the control interface too.
Most Likely Causes
- Dish or rack interference Items are loaded improperly or the racks are not fully seated, so the door cannot close completely.
- Door latch misalignment or wear The latch is not engaging the strike correctly, or the latch mechanism is damaged or bent.
- Leveling or installation issues The cabinet or dishwasher is out of level, so the door does not align with the strike.
- Control or interface issue A stuck button or panel problem can mimic a door problem on some models.
- AutoRelease setting (select models) Samsung advises checking AutoRelease on models that use it, because the feature can affect normal door behavior.
How to Diagnose and Fix
- Verify whether the door physically will not close, or whether it closes but the dishwasher still thinks it is open.
- Pull both racks fully into the tub, remove any tall or protruding dishes, and retest the door closure.
- Check that the unit is level front-to-back and side-to-side, and verify the tub and frame are not twisted in the opening.
- Inspect the latch and strike to confirm the strike lines up with the latch opening, the latch moves freely, and the hook is not cracked, bent, or worn.
- Turn off the dishwasher and touch every button on the control panel to check for stuck-button symptoms or interface faults.
- After correcting mechanical issues, close the door firmly and verify the machine starts normally.
- If the door physically closes but the machine still reports a door problem, move to the latch switch or sensor circuit, harness, and control board path based on the model’s design, or contact service.

When to Call a Pro
Contact service when the door physically closes and all racks and loading are correct, but the machine still reports a door problem after you have checked leveling and inspected the latch and strike. Also call a pro if you find a stuck button or panel issue that returns after resetting the dishwasher, or if the door-closed signal still fails after mechanical corrections and you need to test the latch switch, sensor circuit, wiring harness, or control board.
