Effective October 2007, we transitioned to the
White Rodgers Thermostat Control for our standard
Guardian PowerVent residential gas water heaters.
This change affected both natural and LP gas
models. Below is the troubleshooting step for each
potential error code. In the event you display the
code for a flammable vapor event, please call the
technical support line.
Error 1
Indications
An open earth ground circuit to the water
heater.
Troubleshooting
1. Check that the earth ground conductor is properly connected at the fuse box or breaker
panel and the water heater.
2. Check that the grounding conductors on the water heater are properly connected and
secure.
3. Check green grounding wire connection on side of control valve.
Error 2
Indications
The self diagnostic test detected a wiring error
or a high resistance to earth ground.
Troubleshooting
1. Check for proper connection of the line neutral and line hot wires.
2. Check that the appliance is securely connected to earth ground.
Error 3
Indications
The pressure switch remained closed longer
than 5 seconds after the call for heat began.
This error code will appear within 5 seconds if
the pressure switch will not open.
Troubleshooting
1. The pressure switch wiring is incorrect.
2. The pressure switch has been jumpered.
3. The pressure switch is defective (contacts inside switch permanently closed) and must be
replaced.
