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

SOURCE: my rheem water heater is flashing an error code of

This means the solenoid to the modulating gas valve is sharing a fault. You will need to inspect the wiring to the solenoid to make sure it's ok. You can ohm out the solenoid to make sure it's not open. If it is, you will need to replace it.

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

AO smith manuals

GPVH series manual
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

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

Takagi t-k3 runs hot on low to med flow on high turns cold & flame shuts off

OMG 95 PSI is too high a pressure for a tankless! What was the W.C. in inches on the manometer?
Also on a T-K3 12 isn't a Code but a partial Code. You need an R/C to make this easier as counting led flashes produces wrong codes.
you'll have to find the correct code it's throwing not a partial.
And put a Pressure Reducer on this to below 60 PSI. 95 PSI is only impressive when it blows the tubing out after a few years.
Call Takagi in California not A.O. Smith in TN and they'll help someone fix this
