Electronic ignition tries to lite, clicks 5 times, then goes POOF

When the electronic ignition tries to lite the gas water heater, we hear a clicking 3-5 times, then the gas goes POOF and it lites. What can we do to fix the POOFin' that happens.. Would it be adjusting the air shutter or is it a problem with the circuit board?

Gas burners go "poof" when they have too much gas in the area upon lighting. This is normally due to the ignition source not being close enough to the initial source of gas. This is normaally corrected by ensure the main burner is clean so that it distributes the gas correctly and having the ignition source at proper strength and location. I would have to have good schematics of your heater to be more specific. I hope this helps.

Bosch Confort S 13 BP tankless water heater won't ignite, It clicks but no gas going thru valve


The S 13 BP is a simple unit that does not have a pilot light. It uses electronic ignition on demand, which is what you hear clicking. If there is no gas going through and you've verified there is gas to the inlet, then it has to be the gas control valve.

Heater has low voltage and will not run


Attach black on meter, or ground clamp on test light to good ground such as cooper line. Test for 12vdc at gas valve when switch turned on and you hear or see ignitor sparking. If no 12vdc, backtrack. Follow red wire from gas valve to (ECO), (both terminals,) then same to thermostat (THERM) . If you get 12vdc on one side, and 6vdc or no voltage on the other, replace it. If you've got 12vdc going to gas valve, and don't feel or hear it "Click" when trying to ignite, try a quick "rap" on valve to see if it's stuck. If valve is opening and you hear gas, but no ignition, clean burner tube good and retry.

5yr. old aquastar 125x lp wont stay lit after about 5min. use. just started happening out of the blue... a clicking noise preceeds the flame shutting off. any ideas?


The gas valve makes a single click sound when the pilostat shuts off. That is a safety holding coil for units with standing pilot lights and closes if it thinks the pilot went out. In electronic ignition, the same holds true except the sensor is electronic.

I have a G6A-7E electronic ignite water heater.


Make sure propane is on and getting to your stove burners ok, first, then try switching it back on. If it fails to ignite, shut switch off and try a couple of times, if still no ignition, get back to me.

We believe we are to turn on the water electric button to start the heater. Directions say the light should go out when ignition occurs. It won't go out.


If your water heater has an electric element, as well as electronic ignition for gas operation, you may be getting them mixed up. One switch should show like a lightning bolt beside it,(that's for hydro use) the other will show a small gas flame beside it.(that's to turn on ignition for gas operation.)
If you only have one, my guess is it's for electronic ignition. When you turn that on, you should hear the water heater trying to ignite outside.("click,click,click) and then burner should ignite if you have your propane on. Get back to me with your model number of the heater, behind cover outside, and I can tell by that what you have as far as just gas, gas and electric, etc.

Hi Our gas water heater is not igniting


you need to replace the thermocouple its an electronic device that keep the gas flowing . the pilot light is always on and the thermo couple controls the flame. if it goes bad the flame goes out and the burner wont come on to heat the water, they are easy to replace and available at all home depot or a lowes kind of store.

Bosch tankless GWH 1600 H NG won't always ignite. The igniter sparks, but doesn't always light the gas. It just clicks. When installed it lit every time, now it takes more and more tries to get it to...


The manual says to hold a match near the pilot while the ignitor is trying. It says that if the unit lights the pilot orifice may be dirty or clogged. Then the manual says to check the voltage on the igniter. It should be 1.3 volts DC minimum if it is not means the electronic control box is defective.

Let me know the status ...Kevin
