Diagnosis
Connection failure during Wi-Fi setup. The washer's module requires a specific 2.4 GHz network configuration.
How to Fix It
Ensure your phone is on the 2.4 GHz Wi-Fi band. Disable any VPN or ad blocker on your phone. On the washer, press and hold the Remote Start and Delay End buttons for 3 seconds to reset the network module. The Wi-Fi icon will blink. Try the setup in the SmartThings app again.
If That Didn't Work
The router may be blocking the connection. Temporarily disable the router's 5 GHz band and any firewall settings like AP isolation. Place the washer within 10 feet of the router during setup.
Heads Up
Mesh network systems often cause timeouts. Try connecting the washer to the primary router node, not a satellite. The module has limited range.
