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.

LC#
(LC0,

...)
Scale build-up in heat exchanger (when
checking maintenance code history, “00” is
substituted for “LC”)
If remote is fitted: lC0~lC9 indicates that there is
scale build up in the heat exchanger and that the heat
exchanger needs to be flushed to prevent damage.
Refer to the flushing instruction in the manual.
Hard water must be treated to prevent scale build up
or damage to the heat exchanger.
To operate the water heater temporarly until the heat
exchanger can be flushed, push the ON/OFF button on
the temperature controller 5 times.
Reapeted lC codes will eventually lockout the water
heater.
