All tankless systems at times can give an error code if one of the sensors is triggered or something fails. Sometimes its as simple as just opening the front and replacing the failed sensor, other times you may need to hire a technician. Try cross referencing your error on our Navien error code page here. This could help you narrow down the problem and find the replacement if needed.
