What does the Worcester Bosch Greenstar 8000 Lifestyle E133 fault code mean?
The E133 fault code indicates that the boiler has failed to detect a flame during operation. This can prevent the boiler from heating water or providing central heating, leading to a lack of hot water or heating in the home.
Common Causes
- Faulty Ignition Electrode: If the ignition electrode is damaged or dirty, it may not create a spark to ignite the gas.
- Gas Supply Issues: A blockage or interruption in the gas supply can prevent the boiler from receiving the necessary fuel to ignite.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any gas-related issues, including those causing the E133 fault code. Attempting to fix gas appliances without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E133 fault could be around £150 to £250, depending on whether the ignition electrode needs replacement or if there are gas supply issues that require further investigation.
