What to do if my GSW 6G40NAV Water Heater shows a Hard Lockout?
If your GSW Water Heater is in Hard Lockout, the suggested solution is to replace the main controller or, if resetting the control does not clear the fault code, replace the control.
What to do if my GSW 6G40NAV indicates an ECO (Energy Cut Off) Limit Lockout?
To reset the ECO (Energy Cut-Out) on your GSW Water Heater, manual intervention is required. It cannot be reset by cycling power. Here’s the reset procedure: 1. Turn the set point knob to the lowest setting for at least 10 seconds, then return it to the desired set point. 2. You can only manually reset the ECO twice. If the ECO trips a third time, the gas valve will enter a hard lockout, requiring replacement of the gas control.
What should I do if my GSW Water Heater has a Soft Lockout - Recycle Limit - Flame Lost?
If your GSW Water Heater displays a Soft Lockout - Recycle Limit - Flame Lost, here are a few things you can try: 1. Turn the power “OFF” for 10-20 seconds then “ON” again to clear the fault code. 2. Make sure the flame rod is properly seated in the flame; if not, reposition it. 3. Clean the flame sensor rod with fine steel wool to prevent lock-out. 4. If the fault code persists, replace the control.
What to do if my GSW Water Heater displays Pressure Switch Failed Closed?
If your GSW Water Heater displays a Pressure Switch Failed Closed, follow these steps: 1. Check that the blower operates and is free of blockages. 2. Verify that all wiring is correct. 3. Ensure the air pressure sensing tubes are properly connected and not kinked or damaged. 4. Make sure the air pressure switch is correct and the air pressure switch (N.O.) is not bypassed (jumpered). 5. Turn the power to the unit “OFF” and check for continuity of the air pressure switch (N.O.) with wires disconnected: * If the pressure switch contacts show continuity (closed circuit), replace the pressure switch. * If the pressure switch contacts are open and all wiring is correct, replace the Gas Control.
What should I do if my GSW Water Heater shows Soft Lockout - Flame out of Sequence Sensed?
If your GSW Water Heater displays a Soft Lockout - Flame out of Sequence Sensed, here’s what you can do: 1. Turn the power “OFF” for 10-20 seconds then “ON” again to clear the fault code. 2. If the fault code persists, replace the control.
What to do if my GSW 6G40NAV Water Heater displays Valve Fault Detected?
If your GSW Water Heater displays a Valve Fault Detected, you can try the following: 1. Turn the power “OFF” for 10-20 seconds, then turn it back “ON” to clear the fault code. 2. If the fault code persists, replace the control.
What should I do if my GSW 6G40NAV Water Heater shows Temperature Sensor Fault Detected?
If your GSW Water Heater shows Temperature Sensor Fault Detected, replace the gas control.
What to do if my GSW Water Heater shows Electronics Fault Detected?
If your GSW Water Heater shows Electronics Fault Detected, replace the gas control.
What to do if my GSW 6G40NAV experiences Soft Lockout - Retry Limit - Failed Trial For Ignition?
If your GSW Water Heater shows a Soft Lockout - Retry Limit - Failed Trial For Ignition, consider the following: 1. Ensure the gas supply is turned on and the gas pressure meets requirements. If the supply pressure is correct but the manifold pressure is off by more than 0.3” WC, replace the control. 2. Verify the supply voltage is between 115 - 125 VAC. 3. Make sure the flame sensor has good contact with a steady burner flame. 4. Clean the flame sensor with ultra-fine steel wool. 5. Confirm the Hot Surface Igniter is correctly positioned for consistent ignition. 6. Inspect the igniter assembly ceramic insulators for cracks and replace the assembly if damaged. 7. Check the igniter's resistance at room temperature (at the plug). Replace it if the resistance is not within 42-76 ohms...
