John Wood electronic gas water heater shows E014 and the burner does not light; gas odor may be present near unit

Critical safety: If you smell gas, do not light any appliances or operate electrical switches. Ventilate the area and contact your gas supplier or emergency services. Turn off the manual gas shutoff valve to the heater.

• 1. Visual inspection: Check the gas control valve for signs of overheating, corrosion, or physical damage. Do not attempt to disassemble the valve.
• 2. Wiring check: With power off, verify that the gas valve wiring harness is correctly connected and not pinched or damaged.
• 3. Coil resistance: If accessible, measure resistance of the gas valve solenoid coils and compare to manufacturer specs. Replace the valve if readings are out of range.
• 4. Replace gas control valve: If E014 persists and other ignition components are good, replace the entire John Wood gas control valve/thermostat assembly, following all leak-check procedures with a soap solution after installation.
• 5. Professional verification: Have a licensed gas technician verify proper operation and leak-free connections before returning the heater to service.
