Rinnai Error Code 12

What Does a Rinnai Error Code 12 Mean?

If you’re getting Rinnai error code 12 on your hot water unit, it indicates that a flame failure has occurred on the system. In this instance, your hot water unit has not recognised that there is a flame in the burner box. This can be quite a difficult error code to solve yourself, especially if there are more extensive issues occurring within your unit. There are a number of reasons why your Rinnai unit is showing this error code but some of the common causes include:

  • Incorrect gas pressure supply your hot water unit
  • Loose gas connections and fittings
  • Incorrect venting material installed for your specific unit
  • Debris and dirt clogging the gas burner
  • Debris and dirt clogging the fan blower
  • Moisture in the tubing connecting the gas combustion chamber to the gas valve (in internal units only)
  • Damage to the flame rod protective sleeve
  • Damaged flame rod wires

What Can I Do to Solve An ‘error 12’ on My Rinnai Hot Water Unit?

Firstly, check the gas connections and gas pressure to your hot water system to ensure that the pilot light is not out just because there is no gas to the unit. If the gas pressure to the hot water system is insufficient there can be a number of causes, most of which require a qualified gas fitter to correct.

Fortunately, Metropolitan Plumbing employs fully qualified gas fitters who have years of experience repairing and replacing Rinnai hot water systems. No matter what error code your Rinnai system is showing, our plumbers will be able to quickly identify faults and work towards finding a solution. It is imperative that all gas works are carried out by a qualified gas fitter, not only to meet Australian regulations but also to ensure the safety of persons living in the home.

Whether you are requiring thermocouples, elements, or pressure relief valves to be replaced, we can supply and install all parts to get your hot water unit up and running in no time.

Our company operates 24/7, so you can always call upon us to fix your plumbing problems no matter the time of day. Even in the event that your Rinnai hot water system is not repairable, we can provide an on site quotation to replace it and can have your new unit installed and operational on the same day.

Rick arrived within the hour and was diligent in autopsying the wall and ceiling to find the source of the leak. He found that it was an issue of pipe pressure. Our wall and ceiling are safe with no more leaks!
