Question about Water Heaters

Burner didn't ignite on my AO Smith model FXGT/PGXT

After a shower this a.m. the water heater burner did not ignite to heat more water. I had to turn the control all the way to 'very hot' before the burner kicked in. That was fine and the water did heat to 'very hot' . Do you think I will run into that again tomorrow morning? I guess I have not used enough hat water today to run the temp down enough to let the burner kick on again. time will tell.
Thanks for any ideas to look for,
Dave in Denver

Unless your AO is a high recover it will take a while for it to fill up with the water that you have used then reheat the water in the tank.

My water heater heats everything except my lower shower


Let's walk our way thru this one: I assume you have an upstairs shower, and a downstairs shower?-- Are you able to follow the pipes coming out of the Hot Water Heater?-- Can you trace where the pipes to the upstairs shower go?-- And what about the pipes to the lower shower? -- Do they BOTH come off the HOT water pipes coming out of the top of the HW Heater?
A big help in tracing pipes, is by having the hot water run in the Shower that is getting HOT water-- Feel the HOT! pipe?-- Now-- shut that water off, and go to the lower shower-- When it is running, can you hear water flowing out of the pipes at the top of the Hot Water Tanks?-- or do you feel Cold water moving-- Can you travels where it is flowing from? Get back with me, and tell me what you are feeling, and hearing-- Mack B

If the igniter is not turning off, then that would explain early failure, and it would be caused by the control chipset

Igniter is not working


Try removing the igniter. (First turn the heater off) There is a heat sensor rod on the igniter. If it is blackened use fine sand paper or a scotch brite pad and clean it so it is shiney. reinstall the igniter (turn the heater back on) and try it. If that doesn't work the igniter may be defective and will require replacement. I have a smaller A.O. Smith water heater and that little trick has saved me three service calls. Good luck.

AO Smith Water heater FPSH50-260 keeps blowing fuses


FPSH series is a power vented residential gas water heater.

1) The blower is plugged into 120Volt outlet. If blower has short, then it will trip breaker.
Blower could be Fasco model 7021-10195, or 7021-10770. Call AO Smith: 1-800-527-1953. They will need model number and serial number located on label on side of tank.

2) Before calling AO Smith, check outlet with circuit analyzer. Outlet must have correct polarity and must be grounded. Unplug cord to water heater and run continuity test from ground prong on electrical plug to manifold tube on gas valve.

3) Also if a fluorescent light fixture is on the same breaker, that can cause burner to short cycle.

4) Connect water heater to different outlet and see if problem continues.

5) AO SmIth has service manuals for the FPSH series that download to your computer:

I have a Reliance water heater - 40 gal Model


In my first 15 years as a plumber I never saw a pilot light issue on a gas WH that a new thermocouple didn't fix. Since the government mandated a redesign of the fire box, I've seen three that nothing ever fixed - two Whirlpools and one (my usually ultrareliable) AO Smith - including replacing the entire burner assembly and the regulator. And I've heard of many others.

Check the thermocouple connection for tight. (Don't strip.. threaded soft metals.)
Check the microvents on the bottom ? of the burn box for dust, even if it is new.
Call Reliant and demand new units until you get one that works.
Try another model. Consider a 52gal electric.

I've always recommended gas over electric, and AO Smith and Rheem were my recommendations (and "Reliants" were "lumber yard" water heaters. Sorry.)

Since the mandated redesigns, I don't really have a "proven reliable" model to suggest. I increasingly believe the restricted air flow design is the ultimate culprit, including any changes to the thermocouple/regulator construct to accommodate the restricted air flow design. Just my hunch.

Offered for what its worth. -- plumber in Indiana.
