SOURCE: A.O. Smith Water Heater Problems

ok here is how a heater works - there is a high setting cut out and a low settin cut out. The cycle is as follows. The water heater first heats to a preset temperature , say 120 degress. You draw water and the temp in the tank drops to say 90 degrees at which point it fires again- sensing that if it doesn't you will run out of water.I think that this setting has been set too low to say 75 degrees and you get cooler water because the heater cannot catch up. You must find this control in book at set the differential to twenty degress.This will stop you from running out of hot water.Just for the record less reputable companies will do this on purpose over a coulpe visits adn tell you the heater is failing and must be replaced. Get a book. In the mean time I need your model # so I can find this setting for you.Wait to hear from you. Allen

I bet your thermo couple is bad or your ports are clogged? How old is the unit?

SOURCE: I have a GPVH 40 100 AO smith hot water heater.The

AO smith manuals
http://www.hotwater.com/lit/im/r-gas.html

GPVH series manual
http://www.hotwater.com/lit/im/res_gas/315465-000.pdf
You can search the manual for FV

The FV sensor shorted because it detected flammable gas

Quote manual:
Flammable liquids (such as
gasoline, solvents, propane (LP or butane, etc.) and other substances
(such as adhesives, etc.) emit flammable vapors which can be ignited
by a gas water heater's hot surface igniter or main burner. The
resulting flashback and fire can cause death or serious burns to anyone
in the area. This water is equipped with a FV sensor for detecting the
presence of flammable vapors, see Figure 3. When the sensor detects
those vapors, the unit will shut down and not operate. Should this
happen, please refer to the troubleshooting guide on pages 28-30.

Troubleshoot step 14-15 says
replace the FV sensor
call tech assistance number that shows on water heater
AO Smith will refer you to a plumber
I don't believe homeowner can buy these parts due to Federal regulations
The shorted FV sensor probably saved you a flash-over
The cost of 2nd degree burns from a flash-over would be astronomical.
Fortunately you're ok, and the other folk in the room are ok.
In the old days.
Two guys I knew, winter 1978 Chicago, were laying VA tile using the black mastic.
They were killed and the house burned down because of the water heater.
Main office marked the event with a memo saying they still owed money on their account.

The only company with a re-settable FVIR that I'm aware right now is Bradford White

Bradford White Defender FVIR is resettable without buying parts.

SOURCE: I have an AO Smith Model EES 52 917 hot water

You have electric water heater.

Inside the upper panel on water heater is a thermostat with red reset button.
1) Click the reset.
2) Put insulation back over thermostat so it is not exposed to cooler air, so it reads correct temperature.

After resetting thermostat, you will have hot water.
The reset automatically clicks off when thermostat detects temperatures in excess of 150 degrees.
The re-set is a safety device, and it keeps everything safe.
If reset will not 're-set' with cold water in the tank, then thermostat is bad, replace thermostat.
You can repair electric water heater yourself following steps on links below

http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html

If the reset clicks off again, just reset it
This is not a dangerous situation
Reset thermostat as many times as necessary until you can fix the problem

If you have trouble fixing the problem, add a comment at bottom of this page and it sends me an e-mail and I will help further

Water was pouring out the top of my hot water tank and I would like to know can it be repaired at a affordable price or if it need to be replaced will it be affordable it is a Master Plumber Reliance 501...


Unit is probably rusted out:
http://waterheatertimer.org/Leaking-water-heater.html

Reliance is AO Smith. I recommend the AO Smith line-up of water heater brands as best because air intake screen is located on bottom of unit and can be cleaned by homeowner without removing combustion parts, and because AO Smith posts service manuals.

The plug is HOT?
Unplug immediately.
Is the outlet hot? Is the circuit breaker hot. Have you had a surge event or nearby lightning strike?
Do you have electrical issues in home?
Add a comment.

Test outlet for correct polarity, and test for overvoltage and short.

The intellivent is very susceptible to surge and will stop functioning.

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 an A. O. Smith Model FPSH 40-261 hot water heater. It won't heat water. there is a green light on the control flashing. What does it mean?


AO Smith uses the Honeywell ICON gas valve with green indicator light.
Some models use White Rodgers Intellivent with a row of indicator lights.

The gas control blinks the error code:
