Rinnai 12 HW_CF OIM
ERROR CODES
Your Rinnai gas continuous ow water heaters has a self diagnostic capability. If a fault occurs, an Error Code will
ash on the digital monitor of your water controllers or on the status monitor * on the front cover of the water heater.
This assists with diagnosing the fault, and may enable you to overcome a problem without a service call. Please
quote the code displayed when enquiring about service.
*Models: Innity Enviro 16, Innity Enviro 26, B16, B20 & B26 do not have a “Status Monitor”.

In the majority of cases, you may be able to clear the Error Code simply by turning the hot water
tap OFF, then ON again. If this does not clear the Error Code, try pushing the On/O󰀨 button OFF,
then ON again, or turning the power for unit OFF, waiting 10 seconds and then ON again.
If the Error Code still remains, contact Rinnai for advice.
