Question about Water Heaters

1 Answer

On a State Ultra Low Nox system every few weeks the unit status light gives a message that the burner is dirty or clogged. I have cleaned it but it does not seem dirty and it is not clogged. It does not seem to matter if I clean it or just turn the pilot off and relight it. Seems like a safety system nuisance but I am not sure what to do about it.

SOURCE: pilot lights (not always) but gas will not flow into burner

First Clean the ignitor assembly and make sure the flame is reaching the flame sensor strongly.

You may need to replace the flame sensor.

SOURCE: After a few minutes of burner heating the water, gas shuts off.

A couple of things to check:

If possible, remove the pilot gas assembly and clean the gas jet and thermocouple - they can get carboned up and stop working properly. Make sure the pilot flame and deflector is aimed properly and making the thermocouple glow red hot. If the problem persists, you may want to replace the thermocouple and also check the propane regulator.

SOURCE: AO Smith water heater about 4 years old pilot went

It sounds like your flame detector (usually a thermocouple) has gotten weak and when you cleaned the pilot the stronger flame was able to generate enough power to keep the gas valve working. If you replace the thermocouple your problem should go away. If a new thermocouple will not keep the gas valve operating...the coil in the gas valve has gone bad and you will need to replace the gas valve assembly. (most valves do not have replaceable coils).

Kenmore Water heater, Model # 153.339462, Pilot lights, burner burns for approx. 10 - 15 minutes then both go out. after which it is more difficult to light the pilot. I need ideas please


Clean combustion parts, clean air intake, get more air to water heater and see if problem continues.
Look at color of burner flame and pilot flame: if flame has yellow-and-orange instead of clear blue flame, then combustion parts need cleaning.

Pilot and burner problems can be caused by bad thermocouple, thermocouple not sitting in flame, weak pilot flame due to dirty tube or low gas pressure, air in gas line, no draft up vent, backdraft coming down vent, dirty combustion parts, clogged air intake, insufficient air, insufficient air quality, hot attic, bad gas control valve, etc.

Model # BFG1F4040S3N0V RESET BUTTON WON'T STAY LIT


You have a 6 year tank-type low-nox gas water heater
http://www.whirlpoolwaterheaters.com/products/ByCategory.aspx?id=1
Google search 'low nox' for more details about low nox type water heaters that burn fuel so less NO2 irritant is vented into atmosphere.

Owner's manual:
http://www.whirlpoolwaterheaters.com/downloads/6510397.pdf

1) You said 'reset button.' Only mention of 'reset' in manual is about FVIR flammable vapor ignition system where water heater shuts off when exposed to vapors that might catch fire or explode:
This model appears to have Whirlpool's new resettable FVIR so read instructions in manual for resetting FVIR. If FVIR will not reset using instructions, then call whirlpool at 1-877-817-6750

2) You said 'won't stay lit.' Manual has troubleshooting flowchart starting on page 24.
There are 13 items listed for pilot won't stay lit, with possible remedy for each.
There are 9 things for burner will not light, with remedies.
Call whirlpool at 1-877-817-6750

3) Save manual posted above. I install water heaters and tell everyone to read and save manual to empower them to help themselves.

4) Call a plumber for service.

Pilot light keeps going out


Either the pilot light orfice is dirty, and you will need to pull it out and clean it, or the thermocouple is bad. If the pilot goes out as soon as you let the button go then it is most likely the thermocouple. If the pilot stays lit for a few days or hours then you will need to clean the pilot orfice, heres how:
1 turn off the gas supply
2 unhook the main burner gas line from the thermostat, this is the line that goes to the burner
3 unhook the pilot supply line it is usually next to the main burner line
4 unhook the thermocouple from the thermostat
5 remove the burner assembly
6 take the orfice out of the pilot line and clean it out by blowing thru it, use an air compressor if needed.
7 reassemble and light pilot

Rheem gas water heater it won't stay lit...will lite up and go off after 20 seconds or so. If I leave it sit for 20 minutes the exhaust fans blows but no flame and I have to turn off gas and refire up to...


For the main gas valve to come on several conditions need to be met.

The system must detect a pilot light prior to turning on the main gas valve for systems with a standing pilot light (not sure what your system has) and on systems with auto igniters (spark or ceramic heat glo) the control board must detect a flame present at the main burner a few seconds after the main gas valve turns on.

The other condition that must be met on systems with power exhaust systems is a vacuum/pressure diaghram switch must be made and stay made telling control circuits that vacuum/pressure is present = power exhaust fan is on and working.

From your description it sounds as if you may have a dirty/failing flame detector (thermocouple). Remove it and give it a good scrubbing with a scotch brite pad etc. cleaning off any carbon or corrosion/gunk re-install and try it out, or simply spend $15.00 or so and install a new one to be sure. The thermocouple is the metal thin tube that protrudes into the pilot and/or main burner flame and is connected to the main gas valve by a thin capilliary tube.

To check the vacuum swich on the blower a multi meter across the switch terminals looking for a steady "state change" as the blower runs/stops will work.
