ERROR MESSAGES
Rinnai water heaters have the ability to check their own operation continuously. If a fault
occurs, an error code will flash on the Digital Display if you have temperature controllers
installed. 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.
* In all cases, you may be able to clear the Error code by turning the hot water tap OFF, then ON
again. If this does not clear the error, try pushing the On/Off button OFF then ON again. If the Error
Code still remains contact Rinnai or your nearest service agent for advice.
** Faults caused by insufficient gas/water supply or gas/water quality and installation errors are not
covered by the manufacturer’s guarantee.
