STATUS LIGHT TROUBLESHOOTING CHART
LED STATUS PROBLEM CORRECTIVE ACTION
0 FLASHES (LED NOT LIT) Pilot light is not lit. Not enough
power (millivolts) to keep it lit.
Follow the lighting instructions on the front of
the water heater and record any diagnostic
codes. See Status Light Codes section.
1 FLASH (EVERY 3 SECONDS) Normal operation. No corrective action necessary.
2 FLASHES Insuffi cient power (millivolts) to the
gas control valve/thermostat.
Check all wiring connections. If problem 1.
persists proceed to step 2.
Replace the thermopile. 2. If you feel
uncomfortable with this procedure,
contact a qualifi ed technician.
4 FLASHES High water temperature has
activated the over heat sensor.
Replace the gas control valve/thermostat. If
you feel uncomfortable with this procedure,
contact a qualifi ed technician.
5 FLASHES Water temperature sensor failure Replace the gas control valve/thermostat. If
you feel uncomfortable with this procedure,
contact a qualifi ed technician.
7 FLASHES Gas Control Valve/Thermostat
failure.
Replace the gas control valve/thermostat. If
you feel uncomfortable with this procedure,
contact a qualifi ed technician.
8 FLASHES This condition only appears if the
gas control/temperature knob has
been turned off and the thermopile
continued to produce electric
power. This condition can occur
if the thermopile does not cool
down as quickly as expected when
the unit is shut off. This condition
can also occur if the gas control/
temperature knob has been turned
off and the pilot continues to
operate because the pilot valve is
stuck in the open position.
Make sure that the gas control valve/
thermostat knob is set to OFF. Wait one
minute. Remove the outer door. Look through
the sight glass for a pilot fl ame. If a pilot
fl ame is observed with the gas control valve/
thermostat knob set to the OFF position, the
pilot valve is stuck open. Turn the main gas
supply OFF. Replace the gas control valve/
thermostat. If you feel uncomfortable with this
procedure, contact a qualifi ed technician.
If the pilot fl ame is not observed when the gas
control valve/thermostat knob is set to the OFF
position, wait 10 minutes for the thermopile
to cool, then attempt to relight the pilot by
following the lighting instructions on the water
heater’s label. If this condition returns, replace
the gas control valve/thermostat. Contact a
qualifi ed technician if you are uncomfortable
with this procedure.
9 FLASHES Combustion chamber temperature
sensor circuit is open or shorted
Check all connections. If the problem 1.
persists, proceed to step 2.
Replace the temperature sensor. 2. If you
feel uncomfortable with this procedure,
contact a qualifi ed technician. If the
problem persists, proceed to step 3.
Replace the gas control valve/thermostat. 3.
If you feel uncomfortable with this
procedure, contact a qualifi ed technician.
10 FLASHES LDO occurrence was detected
in the combustion chamber
(contaminants)
Reset the system by following these steps: 1.
1.) Turn the temperature adjustment knob
to OFF. 2.) Unplug the thermopile plug
from the gas control valve/thermostat. 3.)
Wait for about three minutes. 4.) Plug
the thermopile plug back into the gas
control valve/ thermostat. 5.) Turn the
temperature adjustment knob to PILOT
and restart the water heater as directed
in this manual. If the problem persists,
proceed to step 2.
Follow the procedure outlined in “Cleaning 2.
the Combustion Chamber and Flame-
Trap.” If the problem persists, proceed to
step 3.
Shut off the gas supply to the water heater 3.
