LED STATUS PROBLEM CORRECTIVE ACTION
0 FLASHES (LED NOT LIT) Pilot light is not lit. Not enough Follow the lighting instructions on the front of the
power (mitlivolts) to keep it lit. water heater and record any diagnostic codes.
See Diagnostic Status Light Code section.
1 FLASH (EVERY 3 SECONDS) Normal operation. No corrective action necessary.
2 FLASHES Insufficient power (mitlivolts) to the 1. Check all wiring connections. If problem
gas control valve/thermostat, persists proceed to step 2.
2. Replace the thermopite. See "Replacing the
Pitot/Thermopite Assembly."
4 FLASHES High water temperature has Replace the gas control valve/thermostat. See
activated the over heat sensor. "Removing and Replacing the Gas Control Valve/
Thermostat."
5 FLASHES Sensor failure Replace the gas control valve/thermostat. See
"Removing and Replacing the Gas Control Valve/
Thermostat."
7 FLASHES Gas Control Valve/Thermostat Replace the gas control valve/thermostat. See
failure. "Removing and Replacing the Gas Control Valve/
Thermostat."
8 FLASHES
This condition only appears if the
gas control/temperature knob has
been turned off and the thermopite
continued to produce electric
power. This condition can occur
if the thermopite 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 flame. If a pilot flame 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. For instructions, see "Removing and
Replacing the Gas Control Valve/Thermostat."
If the pilot flame is not observed when the gas
control valve/thermostat knob is set to the OFF
position, wait 10 minutes for the thermopite to coot,
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. See "Removing and Replacing the Gas
Control Valve/Thermostat" for instructions.
