to light, a water heater does not require you a qualified person or great effort.

To know how to fix a water heater pilot light to yourself without calling a qualified person which cost you a lot of money here what to do please follow all instructions and steps that we will show you below:

How to light a water heater pilot light?

1. Turn the control knob to “Pilot”

• Press the knob in fully and hold it in. (The knob will jump in about 1/4- inch whether it is set to Pilot accurately.)

2. While holding the control knob in

• click on the igniter button constantly for as much as 90 seconds or till the Status Light begins to blink.
If the standing mild doesn’t start to blink after 90 seconds

• STOP. Release the control knob.
• Wait 10 minutes before attempting to relight the Pilot. Repeat these steps 2-Three instances, if needed.

The circuitry in this valve requires that you wait 10 minutes between lighting attempts.
If the Status Light blinks

• launch the management/temperature knob and switch it to the specified setting. (“Hot” is approximately 120°F).

How to fix a water heater pilot light?

Step1. If the Status Light Does Not Blink:

1. Wait 10 minutes earlier than one other lighting try.

2. If the standing light didn’t blink:

• repeat the lighting course by following the lighting instructions on the water heater’s label.

• Remove the outer door.

• The control knob has to be set to Pilot and held in constantly whereas clicking the igniter button (about as soon as per second for as much as 90 seconds).

To observe the Pilot:

• take away the outer door and look at employing the viewport (sight glass).

3. Continue clicking the Igniter button (for up to 90 seconds) until the pilot lights.

4. Once the pilot is lit, proceed to carry the management knob in till the Status Light begins to blink.

5. Release Control Knob and set Knob to the specified temperature setting. (“Hot” is roughly 120°F.

6. Replace the outer door.

Step2: If the Pilot Does Not Light:

1. Wait 10 minutes earlier than one other lighting try. If the pilot doesn’t light, the Igniter is probably not sparking or the unit might not be getting gas (or for a brand new setup, there should be air within the gas line).

Each time you click on the igniter button, you must be capable to :

  • see the spark by wanting to use the viewport. (You might need to darken the room lights to see the spark.)
  • You don’t have to push the Control Knob in to test the Igniter button.
  • Simply look by way of the sight glass whereas clicking the Igniter button and search for a spark.

If you may see a spark when the Igniter button is clicked

  • test the wiring connections from the Igniter button and make it possible for they’re tight.

2. If you see the igniter spark

  • attempt relighting the pilot by following the directions on the water heater’s label.
  • Ensure that the gas provide is turned on. There could also be air within the gas line, and several other lighting attempts could also be wanted to fill the line with gas and successfully light the pilot.

Step3: If the Pilot Lights however the Status Light Does Not Blink:

1. If the pilot lights, proceed to carry the management knob in till the standing light blinks.

If the pilot is lit and stays lit for 90 seconds and the Status Light nonetheless doesn’t blink, the thermopile connections could also be unfastened, the thermal change might be reset, or the thermopile could also be defective.

2. Remove the outer door.

3. Press the reset button on the thermal change (TCO switch).

4. If the swap clicks, it could have tripped.

  • Do not light the pilot if flammable vapors are current.
  • Check flame arrestor for indicators of discoloration (which may very well be attributable to flammable vapors).

 If the flame arrestor is discolored:

  • don’t try to relight the Pilot
  • Check the wiring connections from the thermopile and thermal change (TCO) to the control valve/thermostat.
  • Ensure that every one wiring connections are tight.

6. Replace the outer door.

7. Wait 10 minutes and attempt to mild the Pilot in response to the instructions on the water heater’s label.

8.  While clicking the igniter button constantly

  • the control knob should be set to Pilot and held in until the Status Light blinks.

Once the status light blinks

  • launch the control knob and set the knob to the specified temperature setting. (“Hot” is roughly 120°F.)

How to diagnostic flash codes?

to diagnostic flash codes, we are going to present you the essential situations and learn how to repair them,  comply with these directions under :

In every case, the flash code will happen, adopted by a 3-second pause, after which will repeat.

Step1: zero Flashes (LED not lit)


Control Off/Pilot Out.


1. Follow the lighting directions on the entrance of the water heater and try and relight the pilot.

2. If the pilot will light but doesn’t maintain

  • test for a tripped thermal switch. (Measure continuity by inserting a meter lead on each of the two terminals. Continuity implies that it was not tripped.)

If the thermal change is tripped

  • verify for flammable vapors within the space and be certain that the unit has satisfactory combustion air and correct draft earlier than relighting. (You can reset the thermal switch by urgent the reset button in its center.)
  •  be certain that the filter and flame arrestor is clear

3. If the pilot will light and does maintain, file any standing codes and observe the procedures referring to that code

4. If the pilot won’t light at all

  • confirm the piezo igniter is producing a spark and the unit is getting the right to provide strain.
  • See “Testing the Igniter System” and  “Gas Pressure Checks” .
  • check the thermopile wiring connections

Step2: Status Light On (solid)


The pilot light was not too long ago extinguished and the thermopile is cooling down.


1. Turn the control valve/ thermostat knob to OFF.

2. Wait 10 minutes for the thermopile to chill, then attempt to relight the pilot by following the lighting instructions on the water heater’s label.

NOTE: This control valve/ thermostat has built-in circuitry that requires ready 10 minutes between lighting attempts.

Until the Thermopile reaches its regular working temperature, the standing light is not going to blink, even when the pilot is lit.

It could take as much as 90 seconds of continuous pilot operation earlier than the thermopile reaches regular operating temperature and the Status Light begins to blink.

Step3: one flash


Normal Operation (brilliant/dim heartbeat)


 No corrective motion is critical.

Step4: two flashes


Thermopile voltage low. C


1. Check all wiring connections for unfastened or broken wires. Correct if wanted.

2. Check the millivolt output on the thermopile. If the output is lower than 350 millivolts DC, substitute the thermopile

Step5: Four flashes


Temperature exceeded (ECO activated).


 1. Turn control valve/thermostat knob to OFF.

2. Turn the primary provide OFF.

3. Replace the control valve/ thermostat.

Step6: five flashes


Sensor failure.


 1. Turn control valve/thermostat knob to OFF.

 2. Turn the primary provide OFF.

3. Replace the control valve/ thermostat.

Step7: seven flashes


Internal control failure.


 1. Turn control valve/thermostat knob to OFF.

 2. Turn the principle supply OFF.

3. Replace the control valve/ thermostat.

Step8: eight flashes


 Power off failure.


 1. If the pilot flame is current when the control knob is ready to the OFF place, substitute the control valve/thermostat.

2. If the pilot flame isn’t current when the control knob is ready to the OFF place, wait 10 minutes for the thermopile to chill, then relight the unit. If this situation returns, substitute the control valve/thermostat.
