1. Pilot Will Not Stay Lit
A thermocouple issue is the most common cause, but if replacing the thermocouple does not solve the problem, the gas control valve may be failing.
2. Water Temperature Inconsistent
A failing gas valve may allow gas to flow intermittently, causing the water temperature to fluctuate between hot and cold during use.
3. Burner Flame Is Yellow or Lazy
A healthy burner flame is blue and sharp. A yellow, orange, or lazy flame indicates incomplete combustion from incorrect gas metering.
4. Gas Odour Near the Water Heater
A gas smell near the water heater gas valve area indicates a leak — the valve itself may be cracked or the connection is compromised.
5. Error Codes on Electronic Gas Valve
Modern gas water heaters with electronic gas control valves display error codes for valve-related faults. These codes typically require professional diagnosis.
