Samsung models: Samsung front-load pump filters (WF series) are behind a push-open panel at the lower-right of the front fascia; top-load models (WA series) have no user-accessible filter. The SmartThings app can read active error codes on Wi-Fi-enabled models and often clarifies which sub-component triggered the fault.
Common causes
- Door not closed firmly enough to engage the latch
- Object caught in the door seal preventing full closure
- Worn or broken door latch/catch
- Door lock wiring harness loose
Step-by-step fix
- Open the door and check the rubber seal for small items of clothing caught in it.
- Close the door firmly — listen for a click.
- Inspect the latch hook and catch for visible damage.
- If the door closes but the error persists, the door lock module may need replacement.
Tools you may need
FlashlightScrewdriver set (if replacing lock)
Prevention
- Check the door seal for small items after each load.
- Do not overstuff the drum, which puts pressure on the door seal.
When to stop DIY
Call a technician if the lock clicks but the machine still shows the error — the lock module's internal microswitch has likely failed.
