Samsung Washer Error Code WF — Wi-Fi Connection Error
What this means
The WF error code appears on Samsung smart washers with Wi-Fi capabilities. It indicates the washer cannot connect to your home Wi-Fi network. This only affects smart features (SmartThings control, remote start, cycle notifications) — the washer will wash normally without Wi-Fi. The issue may be with the router, signal strength, or the washer's internal Wi-Fi module.
Alternate codes: WiFi
Step-by-step fix
4 stepsPower cycle the washer and router
Unplug both the washer and Wi-Fi router for 2 minutes. Plug the router in first, wait for it to fully boot, then plug in the washer.
Smart appliances sometimes drop Wi-Fi after firmware updates or router restarts.
Re-pair through SmartThings
On the washer, press and hold the Smart Control button for 3 seconds to enter pairing mode. Open the SmartThings app and add the washer as a new device.
Delete the washer from SmartThings first if it was previously paired, then re-add it.
Check your Wi-Fi band
Ensure your router is broadcasting on 2.4 GHz. Most Samsung smart washers do not support 5 GHz networks.
If your router has a combined network (same name for 2.4 and 5 GHz), create a separate 2.4 GHz network name for appliances.
Improve signal strength
If the washer is far from the router, signal may be too weak. Move the router closer, remove obstacles, or add a Wi-Fi extender near the laundry room.
Metal laundry room doors and concrete walls significantly reduce Wi-Fi signal strength.
When to call a professional
If the washer never enters pairing mode, the internal Wi-Fi module may have failed. Samsung service can replace the communication board.
