it could be the fact thath the water comming in is what the problem is,, on a well system the water is extra cold and the unit is working hard and with sand aso comming in it makes it harder to keep the temp up on the water,,, flush the tank, put hose on it and open the drin valve with a hose on it turn the cold water on and let it flow till the water comes out clear usually about 5 min,,, get all the sand out and other debris and try it

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).

AO smith manuals
GPVH series manual
You can search the manual for FV
The FV sensor shorted because it detected flammable gas
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.

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
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
