Troubleshooting Error Codes

Error A101 Configuration Data Restore

• Cycle power and attempt to clear alarm. If alarm does not clear, replace display control.

Error A102 Time Clock Needs to be Programmed

• Go to configurations and set the time and date.

Error A103 Time Clock Not Advancing Time Properly

• Cycle power and attempt to clear alarm. If alarm does not clear, replace display control.

Error A104 Water Leak Detected

The presence of water has been detected by the control. Make sure that the water heater doesn't shut down without
interactions from the customer and perform the following checks:
• Visually inspect the unit for leaks
• If no leaks are detected, check water leak sensor for water
• If sensor is not wet, replace leak sensor or control if leak sensor has already been replaced.
• If sensor is wet, proceed to steps for leak resolution

Error A108 Ignition Board Communication Failure

Communication lost between the display board and the ignition control board. The ignition control board will
continue to operate the heater using the last known configuration settings.
• Check wiring between the display and P5 of the ignition control board.
• If all wiring is secure and undamaged, replace ignition control board and/or display.

Error A109 External CO Sensor Alarm

CO sensor detects carbon monoxide above the threshold limit. The unit does not come with a CO sensor. If the unit
does not have one wired directly to it then the configuration setup could be causing a false alarm.
• If there is an auxiliary CO Sensor connected to the unit, follow the sensor manufacturer's instructions for
checking proper operation of the sensor.
• Confirm there are no exhaust leaks from loose vent connections,
• From the front display tap the "Settings" button. Then tap "configs". From the "config. settings" screen make
sure the auxiliary input select is set to "Flow Sensor". If this setting is "CO Sensor" with no sensor connect, it
can produce a phantom A109 code.
Error A110 & A111 Shut-off Valve Monthly Test Close/Open Error
These codes indicate that the monthly test of the automatic shut off valve (premium models only) was not completed
properly. The valve did not close in the allotted time. Every 30 days, the unit shuts the valve and opens it. If it doesn't
see shut indication, these error codes will occur.
• Drain the tank and remove the automatic shutoff valve. Clean any debris from inside valve body and manually rotate
the ball valve to ensure the motor is not seized up.
• Reinstall the valve, fill the tank with water, and clear the alarm. If issue persists replace the automatic shutoff valve.
• You can manually open and close the valve if the drive motor has failed. See page 59.
