F70 — No Communication Between Control Board and Console
F70 (and F71) indicates a loss of communication between the machine control board and the console / user-interface electronics. It is an internal board-to-UI communication fault, not a Wi-Fi / connectivity-module problem. Check the wiring/connectors between the control board and the console, then the boards themselves.

How to fix it
- Verify the home Wi-Fi router is on and the network name/password haven't changed.
- Confirm 2.4 GHz band is broadcasting (separate SSID or mixed-band).
- On the dryer, follow the Maytag/Whirlpool app prompts to re-pair via the Wi-Fi/Connect button.
- If the dryer can't see networks at all, unplug the dryer for 1 minute and retry pairing.
- If still failing, replace the Wi-Fi module/communication board.
- Confirm operation by issuing a Remote Start from the app.
