Rinnai Error Code 12

Rinnai Continuous Flow Water Heater Fault or Error Code 12 Troubleshooting Guide

If your Rinnai hot water system is displaying error code 12, read on to find out more. Rinnai gas continuous flow water heaters have an error code feature. If there is a fault, an error code is displayed on the system or temperature controller.

Some error codes have troubleshooting steps you can take to find and fix faults. Others do not and a technician will need to be called to resolve the problem.  Error code 12 has troubleshooting steps you can work through before calling a technician.

Rinnai Error Code 12 Troubleshooting

Error code 12 indicates your Rinnai hot water system has a flame failure or low gas flow. If you encounter error code 12, you can try the following steps to fix the problem:

  • Check gas is turned on at the gas metre or cylinder
  • Check gas is turned on at the water heater
  • Check there are no obstructions to the flue outlet

If you have completed these steps and error code 12 remains, your next step is to call a qualified technician.

Please note that you should never attempt to take apart your hot water system in search of faults. Doing so creates an extreme safety hazard to you and your property. It also voids any warranties covering your system.

Leak Fixed!

I had an issue with water leaking under the sink, had water dripping from a cold water flexi hose. Rang Jim's Plumbing and Cameron arrived within 20 minutes. He thoroughly investigated where the leak was coming from, was very friendly and explained what to do if there were any more issues. Very happy with the quick service provided.

Thank you for my dishwasher

Trent installed my new dishwasher here in Bundoora. He did an excellent job and even started my new dishwasher so it is ready to use. He was polite, neat and tidy. Thank you.
Irene, VIC 5 stars rating

So quick!

Jayden was sent to fix my washing machine taps. He was polite and friendly, and explained what needed to be done. It was a bit more expensive than I expected, but from my call for service to the job being completed was only two hours. I would definitely recommend!
