Error Codes - Rinnai Neo Series Operation Manual

Error codes

The Neo has self diagnostic electronics that monitor the appliance during
start up and operation. Should a fault occur the heater will shut down. The
fault that has caused the shut down will be indicated by a pair of flashing
numbers in the error display window in the lower left hand side of the frame.
The error will show through two narrow cutouts—you will need to walk up to
the fire and look down to see these.
