Rinnai Continuous Flow Hot Water Heater Fault or Error Code 12 Troubleshooting Guide
Should you currently have a Rinnai Infinity continuous flow hot water heater installed on your property you may, at one time or another, experience a Rinnai fault code showing on your system or hot water temperature controller.
These Rinnai fault codes are an excellent feature provided by Rinnai as they easily provide a diagnosis of what the problem is with the hot water heater to allow for a prompt repair.
One of the error codes that you may come across is the Rinnai hot water fault code 12.
Rinnai fault code 12 troubleshooting
The Rinnai error code 12 in relation to your continuous flow hot water system indicates that there is either a flame failure or a low gas flow.
It is advised that when first noticing any fault code on your digital or status monitor that you should try to clear this by turning the hot water tap off and then on again. If the code still appears try pushing the on/off button to off and then push on again. If the fault code still remains then there is definitely an issue that needs to be attended to.
In the case of a Rinnai fault code 12 you can try the following prior to calling in a qualified service technician;
- Check that your gas is turned on at the water heater and gas meter
- Check that no obstructions are blocking the flue outlet
If one of the above was the cause of the Rinnai error code 12 and you have been able to rectify the issue your hot water system should now be working as normal once more. If your gas is turned on and you could not visibly see any obstructions without having to dismantle any part of the unit, and the Rinnai fault code 12 remains, then your next step is to call in a qualified professional.
Please take note that you should never attempt to take apart your hot water system yourself if you are unqualified – doing so could cause an extreme safety hazard to yourself and your property, and will void any current warranties that may be in place.
