LED light meanings

LED color or pattern

What it means

What to do

Green (solid)

The EN module is connected to your router and ready to be set up in the Gecko App.

Open the app to start setup. If the light changes color, check the table below for the new status.

Yellow (solid)

The module is initializing. This usually lasts a few seconds after powering on.

Wait a moment. If it stays yellow for more than a minute, unplug the power cord and reconnect it.

Red (solid)

The EN module isn’t detecting your router.

Check that your router is powered and working. Ensure the Ethernet cable is plugged in firmly at both ends. Try another cable or LAN port. If the router and cable are fine, the module may need servicing.

Red (rapid blinking)

The module is installing a firmware update.

Do not unplug or power off during the update. Wait a few minutes. If blinking continues for more than 5–10 minutes, restart the module. If the issue persists, contact support.

Blue (solid)

The module is fully connected to the internet and the Gecko cloud. It’s already linked to a user account.

Everything is working correctly. Use the Gecko App to control your spa.
⚠️ Note: Once the module is set up, it can only be used with the same account that first registered it.

Purple (solid)

The module is connected to your router but can’t reach the internet.

Check your internet connection and router settings. Ensure your ISP connection is active and stable.

White (slow blinking)

A critical error has occurred. The module’s identity can’t be verified.

This can’t be fixed through the app. Contact Gecko Support for assistance or replacement.

Slow blinking (any color except white)

The module is in pairing mode and not yet connected to the spa.

The EN (Home) and CO (Spa) modules need to be paired. Turn off the spa breaker, wait a few seconds, and turn it back on to complete pairing.

Blue (rapid blinking)

The module is saving a backup of its software.

Do not turn off the device during this process. If blinking continues for more than a few minutes, restart the module.


Tips for setup and troubleshooting

  • The EN module’s LED will go through several colors during first-time setup — this is normal.

  • Wait for the solid green light before adding your spa in the Gecko App.

  • Keep the EN module powered and connected at all times for reliable remote access.
