What does the Glow-worm Easicom E119 fault code mean?
The E119 fault code on the Glow-worm Easicom indicates that the boiler has detected low water pressure in the 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 heating system or insufficient water being added to the system.
- 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 fix low water pressure by checking the pressure gauge on your boiler. If it is below 1 bar, you can use the filling loop to add water to the system until it reaches the recommended level. However, if you suspect leaks or other issues, it is advisable to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated cost for addressing low water pressure issues, such as refilling the system or replacing a faulty pressure relief valve, could range from £100 to £250. This includes the cost of parts and labour, depending on the specific issue identified.
