Poolex pool heater does not respond to external Wi-Fi or smart control app.

Safety: Only low-voltage components are involved, but still turn off power before plugging/unplugging modules.

Steps:

• Check Wi-Fi signal: Use a phone near the heater to confirm strong Wi-Fi coverage.
• Reset module: Follow Poolex instructions to reset and re-pair the Wi-Fi module with the app.
• Inspect connection: Ensure the Wi-Fi module is firmly plugged into the designated port on the Poolex control board.

If the module still does not connect, replace the Poolex Wi-Fi module or consult Poolex support for firmware updates.
