Rinnai Error Code 3

What Does the Rinnai Hot Water Error Code 3 Indicate?

The Rinnai error code 3 indicates a fault caused by a power interruption during an automatic bath fill. The error code 3 will only be present if you are operating your Rinnai continuous flow hot water heater with a wired or wireless temperature controller that provides the bath fill capability.

If a power interruption occurs during the automatic bath fill the water will not continue to flow upon the power being reinstated and the Rinnai error code 3 will begin to flash on the digital status monitor on either your unit or water controller.

The Rinnai error code 3 may appear on any of the following models of Rinnai continuous flow hot water heaters:

  • Infinity 16
  • Infinity 20
  • Infinity 26
  • Infinity 26i
  • Infinity 26 Touch
  • Infinity 32
  • Enviro 26
  • Enviro 32

You may easily be able to fix the issue yourself without the need of a service call by following the steps below:

How to Clear the Rinnai Error Code 3

You should be able to clear the Rinnai fault code 3 by turning all of your hot water taps to the off position and then pressing the on/off button on your hot water system to off and then turn it back on again. The code 3 fault code should now be removed and you should be able to continue running your bath once more.

Should the Rinnai fault code 3 appear again after following the above steps this may indicate a problem with your property’s power supply and it could be worth calling in a qualified electrician to have this looked into.

If you experience any other issues with your Rinnai Infinity continuous flow hot water heater then call the highly skilled Rinnai hot water experts from Jim’s Plumbing.
