This self-diagnostic tool is extremely handy to allow you to easily see what the problem is that is causing your hot water heater to not run as it should be.

If a service call is required to fix the issue you can simply advise your attending technician of the Rinnai fault code displayed so they can provide a quick and easy repair job.

What is a Rinnai error code 79?

If a Rinnai fault code 79 is flashing on the digital monitor of your hot water heater this signifies that a water leak has been detected with the unit.

Many hot water systems will produce condensation during their operating process but if there is excessive leaking not caused by condensation, or leaking somewhere within the system, then the Rinnai error code 79 will display and the issue will require a repair.

Rectify a Rinnai fault code 79

To remove the Rinnai error code 79 yourself you can try turning your hot water tap off and then on and also pushing the on/off button on your water heater monitor.

This will test if the fault code was just a trip of the system.  If the error code 79 remains, or is removed but then re-appears at a later date, then it is time to call in a fully qualified plumber for an inspection on your hot water system.

For a prompt, professional and reliable repair on your Rinnai hot water heater call the experts from Jim’s Plumbing and advise that your hot water system is showing a fault code 79.
