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
The gas control valve/thermostat
hassensedmainburnerame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 temperature in the tank has
exceeded195°Fandhasactivated
the ECO (energy cut off) high
temperature limit.
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
Self diagnostic check has detected
that 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
Self diagnostic check has detected
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
Self diagnostic check has detected
a problem with black resistor wire
on the ignitor assembly plug;
resistor wire is open or shorted.
1 Turn off power to the water heater. Ensure black
resistor wire is not cut, missing, and is installed
between pins 3 & 4 of ignitor assembly plug. Replace
ignitor assembly if damaged or defective.
2 Replace the gas control valve/thermostat if the error
code persists.
15
Self diagnostic check has
determined resistance of the black
resistor wire on ignitor assembly
plug is not within tolerance.
1 Turn off power to the water heater.
2 Replace the igniter assembly plug.
3 Replace the gas control valve/thermostat if the error
code persists.
16
The gas control valve/thermostat
has detected the air pressure switch
circuit is opening repeatedly during
one heating cycle.
1 Ensure air pressure switch hose is not kinked or
clogged, ensure the blower housing is clear of any
condensation.
2 Check vent temperature limit switch - if it is determined
that the vent temperature limit switch is opening its
contacts at normal operating temperatures during
heating cycle - replace the vent temperature limit
switch.
