Rinnai RL94i - Produces hot water for 3 minutes, then stops


I just had this exact problem. It kept getting worse until we had no water. Our Rinnai tankless hot water heater started the same way though, with hot water for a few minutes and then would shut off with an error code 10. We just had to shut the hot water off and then back on, wait a minute or so and we had hot water back for a few minutes. Our unit would come on with a loud vibrating noise and remain until it shut off with an error code 10 (air flow fault). The solution was to remove the blower fan and blow out the squirrel cage. Ours had moths in it. We also vacuumed out the fan housing. Be careful to mark any wires you disconnect and take pictures before removal. Our unit is now almost silent when it comes on and supplies endless hot water.

Is there a reset button for a 6G50NVH-FV-02 hot water heater


Depends on gas control valve, and if cause is overheating high-limit event or FVIR flammable vapor event.
Turn off water heater when using flammable vapors, clean burner parts to prevent overheating.

1) GSW Residential power vent gas water heater with FVIR system:
Some models have intelli-vent gas contol
Others have robershaw gas control with auto-reset

2) Parts manual shows #15 'auto-reset' high limit switch on the blower
http://www.gswpartsonline.com/model/27484
http://www.gswpartsonline.com/schematic/137/view

3) Possible manual:
http://www.gsw-wh.com/pdfs/GPD135NInstall.pdf
Shows resettable lockout page 15
Water temperature must be 120 degree F or lower for reset. Unplug power cord, and then plug back in and wait 15 minutes or 60 minutes depending on gas control valve.
Some intelli-vent controls must be replaced when 195 degree high limit event locks out the water heater.
If high-limit lockout repeats, then gas control must be replaced.
Also clean burner parts, air intake, and make sure flame is clear blue. and not yellow-or-orange.

4) Intelli-vent service manual might apply to your water heater:
http://waterheatertimer.org/pdf/Intellivent-service-manual.pdf

If FVIR flammable vapor event locked out heater, then unplug heater and plug back in.
Immediately press two temperature buttons. Wait for green light to blink. Release buttons.

We change the burner for the water heater, it stay li ari=ound 35 minutes, heat the water and after is turning on completely, even the small flame don't stay lit. What we need to do?


you mean it is only staying on for 35 minutes, if this is the case, then readjust or replace thermal coupling, if bad it will not sense the flame or pilot light. it has to be in pilot light flame as to work properly. ( this is for a gas hot water heater). if bad it will shut gas off to heater.

It sounds like your main valve. The diaphram may be loose fitting or it has a small leak.

Blower not turning on


push the priority button unplug the unit for 1 min,, plug it back in set the temp to the lowest setting it has to start on the lowest setting turn on a faucet on the hot side, turn it on set the temp after it comes on and it should stay on,, if not check the vent make sure there is nothing around it on the outside it can not have anything blocking it,, all the flue connections have to be in the same way they lock into position and it can determin thru the computer if they are not together it draws in the exhaust fumes and shuts it self down
