Question about Rinnai RHFE-556WTA Direct Vent Heater NG Air Conditioner

1 Answer

I have a Rinnai Energysaver 556F

It worked great last year, now this year you turn it on set the temp that you want it works it heats up blows warm air, but then stops after a cycle like 5 min. All of the light in the temp setting and the on button are blinking. If you turn it off then on again, it will do it again?

The heater will have some error codes stored in it. To retrieve them get an assistant to write down the codes as you see them. They come quickly. OK to get the codes, push down on the Economy button and the up arrow and down arrow at the same time. Hold for three seconds. It will take three fingers to do this. Once you get the error codes, look in your owners manual to diagnose.

Here is a link to the 556FTR from Australia.
They are all pretty much the same. The US site has similar info. Just google Rinnai. Open the site, go to resources tab and click downloads. The manuals are easy to locate.

My tank says I have 32 gallons left but the heater won't work (rinnai 556f). It turns on for about 15 seconds and the light on the power button turns red and starts blinking. What does this mean?


If you hold down the economy button and the up and down arrow buttons for 5 seconds the unit will start an error code display. Get a helper and yell out the numbers when they start blinking. Post the error codes and we can help you

Rinnai Energysaver 1001FT, ignites, blows 5mins then shuts down.


Sounds like it is reaching high limit...either the filters on the back are plugged, or the manifold pressure isn't adjusted properly. IF the exhaust were plugged on the unit, it wouldn't fire at all, since it has a pressure switch to verify vent flow. The slightest blockage, the unit will lock out to prevent damage to the unit.

Try disconnecting the unit and thoroughly cleaning the dual walled intake and vent pipe that goes through the wall. Use a small brush to make sure the passages are free from any obstructions. These units have safety mechanisms that are very sensitive and sometimes will shut off when something as seemingly insignificant as a leaf or spider web creates a slight blockage. A yearly inspection and clean out are necessary.

Rinnai 556F Not Exactly and "Energy Saver"...


Raise the thermistor. It is a black rubber probe located on the back of the heater close to the coldest spot in your home, the floor. Raise it a few inches. To do this you will need to unhook it from its holder and open the front of the heater to unravel the extra length of yellow wire.

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?
