Check whether Stay Connect is active in SmartThings. The model manual describes up to 24 hours of connected standby with the door closed and Smart Control, Door Lock and Wi-Fi icons illuminated.
Models covered
WF45A6400AW/US; match the complete model suffix and the cited manual/control panel before following a sequence.
Wait for motion to stop and the door or lid to unlock. Water may be hot. Isolate power and follow the exact manual before any user filter maintenance. Never open a filter against a full drum, force a lock or bypass an interlock.
Compare the behavior
Match the documented control, cycle or feature before interpreting the result. The comparison below keeps normal model behavior separate from an unresolved fault.
| Observed state | Interpretation / next step |
|---|---|
| Finished wash; three relevant icons lit | Check Stay Connect setting. |
| Water remains in drum | Investigate draining, not only connectivity. |
| Remote-ready state ended after unloading | Recheck local Smart Control before remote use. |
Model-specific checks
Three icons provide the useful comparison
A finished cycle with those indicators is different from an unresponsive washer full of water. Record whether the drum is visibly empty of water and whether the panel responds. Do not treat a Wi-Fi icon alone as evidence of Stay Connect.
Separate remote readiness from physical access
The feature keeps a connected state after washing. Use the normal Smart Control and power controls as described in the manual when ending that state; do not defeat the lock to unload. If controls do not respond or water remains, investigate those conditions before attributing everything to the app.
If remote starting later fails
Document whether the door was opened or the washer powered off between enabling remote control and the attempted start. Recheck the local Smart Control state after reloading rather than assuming Wi-Fi connection alone authorizes remote operation. Use Samsung support if the state cannot be reconciled with the exact manual.
What to record next
The key distinction is connectivity versus a remote-ready operating state. A working network does not prove that the washer is currently ready to accept a remote start.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
