What does the Baxi 600 Series E119 fault code mean?
The E119 fault code on the Baxi 600 Series indicates low water pressure within the heating system. This can prevent the boiler from operating efficiently and may lead to further issues if not addressed promptly.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water supply.
- Faulty Pressure Relief Valve: A malfunctioning valve may allow water to escape, leading to a drop in pressure.
Can I fix it myself? (DIY)
You can attempt to increase the water pressure by locating the filling loop and adding water to the system until the pressure gauge reads between 1-1.5 bar. However, if you suspect a leak or a faulty component, it is essential to call a Gas Safe Engineer for further assistance.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing low water pressure issues could range from £100 to £200, depending on whether it involves simply repressurising the system or replacing a faulty valve.
