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.
