What does the Worcester Bosch Greenstar 8000 Lifestyle E119 fault code mean?
The E119 fault code indicates that the boiler is experiencing low water pressure, which can prevent it from operating efficiently. This issue can lead to inadequate heating and hot water supply if not addressed promptly.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water supply to the boiler.
- Faulty Pressure Relief Valve: If the pressure relief valve is malfunctioning, it may not maintain the correct pressure, leading to drops in water pressure.
Can I fix it myself? (DIY)
You can attempt to fix low water pressure by checking the pressure gauge on the boiler and using the filling loop to add water if necessary. However, if you suspect a leak or a fault with the pressure relief valve, it is essential to call a Gas Safe Engineer for safety reasons.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing low water pressure issues, such as replacing a faulty pressure relief valve, is around £150 to £250. This cost reflects the price of parts and labour for a qualified engineer to perform the repair.
