The next section will explore the causes of the E168 Baxi boiler fault. It will explain why this problem occurs.
The 5 Major Causes of the E168 Baxi Boiler Fault
The E168 fault in a Baxi boiler means there’s a gas supply, ignition, or electrical issue. The five major causes are: gas supply interruptions, faulty ignitions, electrical interference, a bad PCB, and poor maintenance. Each cause affects the boiler’s ability to operate safely and efficiently.
1. Gas Supply Interruptions
Gas supply interruptions are a common cause of the E168 fault. This can result from a closed gas valve, a malfunctioning gas meter, or issues with the gas supply network. If gas flow to the boiler is low or unstable, the ignition fails. This triggers the fault code. Check that your gas supply is active. Also, make sure no external factors are disrupting it, like maintenance or blockages.
2. Faulty Ignition Components
Faulty ignition parts, like the lead, electrode, or flame sensor, prevent the boiler from igniting. These components wear out over time due to constant use or exposure to moisture. If they fail to create or detect a flame, the boiler shuts down as a safety measure. Regular servicing helps identify and replace worn ignition parts before they cause faults.
3. Electrical Interference
Nearby appliances or power fluctuations can disrupt the boiler. This can cause an E168 error. This interference can affect the boiler’s sensors or communication between internal components. A surge protector can help your boiler. Install it away from interference sources to reduce risk.
4. Defective Printed Circuit Board (PCB)
The PCB is the brain of the boiler, controlling all its functions. A defective PCB can cause miscommunication between the boiler’s parts. This can lead to operational errors. PCB failures are often due to wear, overheating, or water damage. Replacing a faulty PCB is one of the more expensive repairs associated with the E168 fault.
5. Poor Maintenance
Poor maintenance contributes to many boiler faults, including E168. Dust buildup, moisture, and lack of service raise malfunction risks. A qualified engineer must service the boiler yearly. This keeps it in top condition and reduces faults.
Knowing these causes helps you spot risks. You can then take steps to keep your boiler reliable. The next section will focus on prevention methods to avoid the E168 fault in the future.
Preventing Future E168 Baxi Boiler Faults
To prevent future E168 faults on your Baxi boiler, maintain it and care for it. Annual boiler servicing is the best measure. It ensures all parts, like the ignition system and PCB, are working. Regular servicing helps find early signs of wear. It prevents small issues from becoming major faults.
Subscribing to a boiler cover contract offers additional peace of mind. Boiler cover includes annual servicing and priority access to engineers. It also covers costs for common faults, like E168. Clean the area around your boiler. Ensure good ventilation. Protect it from power surges. These steps reduce the risk of faults.
Disclaimer
Any work beyond the basic steps in your boiler’s manual must be done by a Gas Safe registered engineer. DIY repairs can be dangerous and may void your warranty. So, always get a professional for diagnostics or repairs.
