Yes, an IE error code (frequently seen on Navien tankless units indicating an ignition failure or gas supply error) is a serious operational fault that requires immediate attention. When an IE code triggers, the electronic control board locks out operation and shuts down the gas supply to prevent unburned gas accumulation. While it can occasionally stem from a temporarily closed gas valve, it often signifies low gas inlet pressure, a failing gas control valve, or blocked intake/exhaust venting flues. Verification: Check gas supply valves and inspect venting flues for obstructions before resetting the unit.
