What does 11 mean?
Error code 11 on your Richmond water heater means the unit tried to start but failed to light the burner. This usually happens when the system goes through its ignition sequence, tries to ignite the gas, but doesn't detect a flame. Because unburned gas is accumulating, the unit will shut down as a safety precaution. This is a critical issue because a buildup of gas can create a fire or explosion hazard, or lead to carbon monoxide poisoning.
