Trouble Shooting; Error Codes - Rinnai One 11i Operation And Installation Manual

1.4 TROUBLE SHOOTING

Rinnai products are all equipped with a self-diagnosis system: in case of failure, an error code appears on the control
panel display and flashes. This function can be very useful for diagnosing the problem and tracing the causes, avoiding,
where possible, the need for an external intervention by an authorized Rinnai technician. Write down the flashing error
code before making the maintenance request.
To cancel the error code and to restore the normal operation of the appliance, it is necessary to stop the hot water
withdrawal by closing all the taps for a few seconds. If this procedure does not solve your problem, press the 'On/
Off' key to switch off the appliance, switch off the power supply for a few seconds and reset the unit. If the error code
remains, it is necessary to contact an authorized Rinnai technician.
