Self diagnostic check has detected
a problem with the gas valve driver
circuit, internal microprocessor, or
other internal circuits.
1 Turn the power off for 10-20 seconds, then on again to
clear these error codes.
2 If any of these error codes persist or cannot be cleared,
replace the gas control valve/thermostat.
10
Flame signal sensed out of proper
sequence.
1 Turn the power off for 10-20 seconds, then on again to
clear these error codes.
2 Replace the gas control valve/thermostat if this error
code persists.
11
Water in the tank has exceeded the
maximum allowable temperature,
activating the ECO (energy cut off).
1 Turn the power off for 10-20 seconds, then on again to
clear these error codes.
2 Replace the gas control valve/thermostat if the error
code persists.
12
One or both of the temperature
adjust buttons are stuck.
1 Press and release both temperature adjust buttons
several times - cycle water heater power off and on.
2 Replace the gas control valve/thermostat if the error
code persists.
13
The water temperature sensor
(located in the control valve's
immersion probe) is either open or
shorted.
1 Turn the power off for 10-20 seconds, then on again to
clear these error codes.
2 Replace the gas control valve/thermostat if the error
code persists.
14
either open or shorted.
1 Turn off power to the water heater. Ensure all FV
sensor wiring, the ignitor assembly plug, and the ignitor
assembly socket on the bottom of the Intelli-Vent
control are making good contact. Repair or replace
any worn/damaged components that are not making
good connection.
2 Replace the FV sensor.
15
Self diagnostic check has detected
sensor.
1 Do not touch any electrical switch, do not use any
phone in your building, and do not try to light any
appliance.
2 Smell around the water heater to ensure there are
no gas leaks at the gas control valve/thermostat, in
vapor(s) in the area.
3 Carefully inspect the area surrounding the water heater
for any substances such as gasoline, paint, paint
vapors. Remove anything that can potentially emit
a different location.
4 Call the technical information support phone number
shown on the water heater labeling for further
assistance.

Air pressure switch circuit is
opening repeatedly during one
heating cycle.
LDO (Lint, Dust, and Oil) lockout
condition.
1 On models equipped with a dilution air intake screen on
the blower assembly - check/clean the screen.
2 On models equipped with a combustion air intake
screen on the base ring (bottom) of the water heater -
check/clean the screen.
3 Ensure intake air screen(s) on models so equipped are
not obstructed.
