Common problem: water heater lockout
When the spark is present, but there’s no gas, the issue often stems from incorrect gas pressure or malfunctioning the gas-electric system. Ensure your inlet pressure is set to 11” W.C., particularly when at least two gas appliances are used simultaneously.
For low voltage concerns, the power supply should be adjusted to 10.5VDC. The high-temperature limit switch could also trigger a lockout if it detects unsafe temperatures, serving as a critical safety feature.:
- The main burner tube is blocked. The solution is to clean up the burner tube thoroughly.
- E.C.O. wires or wires on solenoid valve are loose – solution: properly secure the wire connections
- No gas flowing to the solenoid valve – solution: correct the gas supply
The following is when it’s the other way around: there is, but the spark is not present.
- The electrodes attached to the main burner are loose – solution: properly secure the electrodes.
- Improper gapping of the electrodes – solution: reposition your spark gap to that of 1/8-inch and make sure it’s into the flame path
Personal Experience: I encountered a lockout issue during a camping trip. The heater started working flawlessly after checking the gas pressure and adjusting the power supply. Ensuring proper maintenance can prevent such interruptions.
“After replacing the anode rod on my Atwood water heater, I noticed a significant improvement in the unit’s performance. Regular maintenance, like checking the anode rod, is crucial for the longevity of these heaters.”
