STATUS LIGHT AND DIAGNOSTIC CODE TROUBLESHOOTING CHART
LED STATUS PROBLEM CORRECTIVE ACTION
0 FLASHES (LED NOT LIT) Pilot light is not lit or Thermopile
has not yet reached normal
operating temperature.
Turn Gas Control Valve/Thermostat knob to OFF.
Wait 10 minutes, then attempt to relight Pilot by
following the lighting instructions on the water
heater’s label. Until the Thermopile reaches its
normal operating temperature, the Status Light will
not blink, even if the Pilot is lit. It may take up to 90
seconds of continuous Pilot operation before the
Thermopile reaches normal operating temperature
and the Status Light starts to blink.
If the Status Light does not blink after three lighting
attempts, check to make sure unit is getting gas.
Remove the outer door. Press reset button. Replace
outer door. Turn Gas Control Valve/Thermostat
knob to OFF. Wait 10 minutes, then attempt to light
Pilot by following the lighting instructions on the
water heater’s label. Look through the sight glass
for the Pilot flame. If Pilot is not visible, the spark
igniter or gas supply to the Pilot should be checked.
If the Pilot is visible and the Status Light does not
blink after 90 seconds of continuous Pilot operation,
the Pilot flame may not be heating the Thermopile
sufficiently (weak Pilot) or the Thermopile may be
defective, or wiring connectors may be loose.
Replace outer door and verify proper operation after
servicing
NOTE: If the water heater has been operating
but has stopped and will not re-light, check the
flame-arrestor for signs of high temperature (blue
or black) discoloration indicating a flammable
vapor incident. If you suspect a flammable vapor
incident has occurred, do not use this appliance.
Immediately call a qualified technician to inspect the
appliance. Water heaters subjected to a flammable
vapors ignition will require replacement of the entire
water heater. NOTE: Check the gas control valve/
thermostat and thermal switch for any loose wiring
connections, correct immediately.
RED LIGHT ON (SOLID) Pilot light was recently extinguished
and the Thermopile is cooling
down.
Turn Gas Control Valve/Thermostat knob to OFF.
Wait 10 minutes for the Thermopile to cool, then
attempt to relight Pilot by following the lighting
instructions on the water heater’s label. NOTE: This
gas control valve/thermostat has built-in circuitry
that requires waiting 10 minutes between lighting
attempts. Until the Thermopile reaches its normal
operating temperature, the Status Light will not
blink, even if the Pilot is lit. It may take up to 90
seconds of continuous Pilot operation before the
Thermopile reaches normal operating temperature
and the Status Light starts to blink.
1 FLASH (EVERY 3 SECONDS) Normal operation. No corrective action necessary.
2 FLASHES Pilot is lit but the Thermopile is
not producing the required output
voltage.
Turn Gas Control Valve/Thermostat knob to OFF.
The Thermopile is probably defective, but loose
wiring connections or a weak Pilot flame can also
cause this symptom.
