Errors signal issues like ignition failure, flame problems, heat exchanger faults, or communication errors.
Power off for 30 seconds, then restart; use the reset button if available, or call a technician if errors persist.
Minor resets and sensor cleaning may be DIY, but persistent or electrical issues need professional service.
Flush annually, clean filters, check ventilation, maintain water pressure, and schedule yearly servicing.
If errors persist, hot water stops, or you detect gas leaks, electrical faults, or unusual noises.
