You may notice a fault code flashing on the digital status monitor of the controller.

With the advanced technology delivered by Rinnai in their Infinity continuous flow hot water heaters, this self-diagnostic feature is extremely handy.

Should any issues arise with the hot water unit the fault code will show on the monitor to enable a fast and affordable repair.

One of the codes that may display during the lifespan of the hot water system is a Rinnai error code 31.

What does a Rinnai fault code 31 mean?

The Rinnai hot water error code 31 signifies that there is a problem in relation to the gas burner thermocouple.

The thermocouple is an important safety sensor within the gas tankless hot water heater which measures temperature.

The purpose of the burner thermocouple is to prevent explosions and the dangerous release of natural gas.

If there is a fault in relation to the burner thermocouple your hot water pilot light may not light at all or the burner won’t stay lit, which will result in no hot water for you.
