Common actions may include checking for gas supply issues, inspecting the venting system, verifying proper water flow, and examining electrical connections.
6. Check for Obvious Issues:
Inspect the water heater and its components for any obvious problems or issues. Look for signs of leaks, loose connections, or unusual sounds or odors.
Ensure that gas and water supply valves are open and that there are no blockages in the water lines or venting.
7. Record the Error Code:
Take note of the error code displayed, along with any relevant information or observations. This information can be helpful if you need to contact customer support or a professional technician for further assistance.
