3. Press the key to clear the fault and resume operation. Be sure to observe the operation of the unit to prevent a recurrence of
the fault.
NOTE: You are allowed up to 5 “resets” to clear a Fault or Error code. After that, the controller will enter an
|E13| Lockout
state.
When servicing or replacing any components of this water heater be certain that:

The gas is off.

All electrical power is disconnected.
When servicing or replacing components that are in direct contact with heater water, be certain that:

There is no pressure in the heater. Pull the release on the relief valve to relieve pressure in the heater.

Heater water is not hot.

The electrical power is off.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service technician.
The appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance that has been submerged could create
numerous harmful conditions, such as a potential gas leakage causing a fire and/or explosion, or the release of mold, bacteria, or other
harmful particulates into the air. Operating a previously submerged appliance could result in property damage, severe personal injury,
or death.
NOTE: Appliance damage due to flood or submersion is considered an Act of God, and IS NOT covered under product warranty.
The water heater has wire function labels on all internal wiring. Observe the position of each wire before removing it. Wiring errors may
cause improper and dangerous operation. Verify proper operation after servicing.

– Blocking Error Codes
CONTROL BOARD BLOCKING ERRORS
CODE SHORT DESCRIPTION LONG DESCRIPTION CORRECTIVE ACTION
E07 Flue Temperature Too High
The Flue temperature has met /
surpassed the maximum limit.
This is first an E07 blocking error
code.
1. Is the tank full of water? This error code will appear if the tank is
dry-fired.
2. Measure actual Flue temperature.
3. Use an ohmmeter to check resistance on flue temperature sensor.
4. Replace sensor if it does not pass the resistance test.
5. If Flue temperature does not return to normal within 15 minutes,
E07 shall become an F07 fault code.
6. Error will clear automatically if Flue temperature returns to normal
within 15 minutes.
E13
Remote Reset Volatile
Lockout
FIVE RESET attempts counter
has been exhausted Service and repair unit per displayed error code. Turn the main
power supply to the unit off and back on to clear out the error code.
E34 Low Main Power Supply
The main power supply is too low
(below 75 VAC) to properly
power the water heater. 1. When main power is brought back to a normal state (over 75 VAC),
water heater will resume normal operation.
2. Measure AC Mains.
E39
Outdoor Temperature Sensor
Error (When Enabled)
The Outdoor Temperature
Sensor is out of normal operating
range, meaning the sensor is
either open or shorted.
1. Check the Outdoor Temperature Sensor. Ensure it is properly
wired and connected, and that there are no breaks, cuts, or other
visible issues with the sensor wire.
2. Use an ohmmeter to check resistance on the outdoor temperature
sensor.
3. Replace Outdoor Temperature Sensor if it fails the resistance test.
E53
Flue Temperature Sensor
Error
The Flue Temperature Sensor is
out of normal operating range,
meaning the sensor is either
open or shorted.
1. Check the Flue Temperature Sensor. Ensure it is properly wired to
the control, and that there are no breaks, cuts, or other visible issues
with the sensor wire.
2. Use an ohmmeter to check resistance on flue temperature sensor.
3. Replace Flue Temperature Sensor if it does not pass the
resistance test.
E64 Blocked Flue
The control detects a blocked
Flue condition.
1. Check the Flue termination. Ensure there are no blockages or
obstructions in the Flue.
2. Check APS switch. Ensure it is properly wired to the control, and
that there are no breaks, cuts, or other visible issues with the wiring.
3. Replace APS switch.
