Worcester Boiler Faults

Worcester C6 Boiler Fault – problem with the boiler fan

The Worcester C6 fault code indicates a problem with the boiler fan. The fan expels combustion gases to ensure safe operation. A malfunctioning fan prevents the boiler from working to avoid gas build-up. The boiler’s control system detects fan issues and displays the C6 error code as a safety alert. A blocked or damaged fan can cause this fault. Faulty electrical connections may also trigger the error. Regular maintenance helps prevent fan-related problems.

Worcester E9 Boiler Fault – problem with the boiler’s heat exchanger

The Worcester E9 fault code indicates a problem with the boiler’s heat exchanger. A blockage or restriction within the heat exchanger can trigger this fault. A faulty temperature sensor or a circulation issue may also cause the error. The E9 fault code appears when restricted water flow affects system performance. A blocked heat exchanger prevents proper water circulation, leading to overheating. A malfunctioning temperature sensor can also activate this fault code.

Worcester A21 Boiler Fault – communication error between

The Worcester A21 fault code indicates a communication error between the boiler and its control unit. This fault often results from wiring issues or a faulty control panel. The A21 fault occurs when communication is disrupted due to loose connections. Faulty wiring or a defective control panel can also trigger this error.

Worcester EA Boiler Fault – air supply issue

The Worcester EA fault code indicates an air supply issue within the boiler. This fault often results from flue or fan problems or a blocked air intake. The EA fault code appears on the boiler’s display to identify the specific issue and assist with diagnostics. A restricted air supply can prevent the boiler from working, ensuring safety by preventing damage and reducing potential hazards.
