Wrong Passcode Error

Activating the generator is a simple one-time process that only takes a few minutes. The activation process is necessary for the generator to run automatically. Some users may see a WRONG PASSCODE message after inputting the activation code in the generator's control panel while attempting to activate their Generac home standby generator.

Note: If you see the WRONG PASSCODE message while trying to connect the generator to Wi-Fi, rather than during activation, see Why Is My Generator Giving Me a “Wrong Password” Error Message When Connecting to the Wi-Fi Network? for more information.

Environment

This article applies to Guardian-series home standby generators with an Evolution controller that are attempting to activate their generator.

Note: Next Generation air-cooled home standby models are activated during the commissioning process and do not use a passcode for activation: How Do I Commission a Generator in the Field Pro Application?

Causes

This error typically occurs when the wrong passcode is entered or the wrong serial number was provided.

Troubleshooting

If you receive a WRONG PASSCODE error, follow these steps:

1. Confirm you have provided the correct serial number to request the activation code. The serial number is located inside the generator on the metal tag toward the floor of the generator on the firewall. See Where Do I Find the Serial Number on My Air or Liquid-Cooled Standby Generator? for more information.
2. Double-check the activation code is correct and that you are entering it properly into the controller.
3. Verify the serial number recorded in the control panel's firmware. To do this, perform a hard reset as shown in the How Do I Perform a Hard Reset on a Home Standby System? article. The serial number will display briefly after the installation wizard as the control panel reboots.

Note: If the serial number on the control panel is different from the generator serial number on the printed label, contact a customer experience technical representative at 1-888-436-3722 with the serial number displayed on the controller.
