Description: Ignition Failure Solution: This error indicates a failure in the ignition sequence. Ensure that the gas supply is turned on and the unit is properly grounded. It may require a service call to check the igniter and flame rod.
Description: Flame Loss Solution: This code appears when the burner flame is extinguished during operation. Check for proper gas pressure, and ensure there are no obstructions in the venting system. If the problem persists, contact Local Plumbing for professional assistance.
Description: Overheating Solution: This error occurs when the heat exchanger overheats. Ensure the inlet water filter is clean and the water flow is not restricted. An annual maintenance check by our experts at Local Plumbing can prevent this issue.
