I had the identical trouble with my Rinnai 431F just now & read the unanswered posts.

I checked my intake & exhaust & found them connected & intact then went out to check the exterior vent assembly. The "bell" or dome was almost entirely clogged with ice.

I suspect the 60 - 76 lights flashing means insufficient combustion air.

Anyway, I took a hair dryer to it & in 10 minutes it was working as well as ever.

This won't help you October posters but if anyone else has this problem in the future I would start with the outside vent assembly. Get a good look right up inside because I would have missed this ice if I didn't get up close with a flashlight.

Here's a good source for manuals too...

I HAVE A JACUZZI HEATER RINNAI 95GS-5 DO THINK PROPANE WOULD WORK ON THIS ITEM


Contact Rinnai, or look at product manual.
Products rated for natural gas do not work with propane.
Propane burns hotter and has more pressure... wrong gas can cause explosion

I have a Rinnai 556F Heater and I set it to a specific Temperature and a temperature higher is always flashing. What is wrong?


The temp you are looking at may be an error code. 72 Room sensor, 68 Over heat, 76.80 Room sensor short, etc. What is the exact code??

Rinnai rhfe-431faIII heater malfunction


Either the high limit switch is either defective or the wire has come off and the circuit is open. It is found under the heat shield on the front of the heat exchanger. Or there is a blockage in the flue or the blower motor is not running. Take the to trim piece off that is closest to the wall and disconnect the gray plastic hose off of the vent termination and try to start the unit. If it starts, you need to clear out the outer ring on the vent termination. If it continues to fail, there is still a problem and now you will need the installer back. Check all electrical connections going to the circuit board while you have the front cover off.

Where is the pilot light on Rinnai EnergySaver 1001F


If you smell gas in a Rinnai you have a big issue. This heater is what is called a direct vent heater with an electronic ignition so the combustion chamber is sealed and the smell of gas is an indication that you have a gas leak. Please call a professional today.

Rinnai tankless water heater


LC is the error code that you get when you have limescale buildup in the heat exchanger. You need to flush your heat exchanger. If you have the manual for your water heater, use it. The manual to mine is attached. The procedure for flushing it is covered on page 12. I suggest that you have a certified Rinnai plumber perform this task as it requires a ciruclating pump and some hoses that you need to connect to your water heater. If you don't perform this task, it is possible that you will need to replace your heat exchanger and this is not something covered by Rinnai's warranty.

Rinnai EnergySaver 556F Heater flashes


I'm picking up a faint propane scent when the heater is completely turned off. When I turn the heater on it lights fine so I don't suspect it's the pilot light. Is this an issue with the installation of the fuel line, or could it still be the pilot? Any ideas on troubleshooting the source?
