What does the Glow-worm Easicom E310 fault code mean?
The E310 fault code on the Glow-worm Easicom indicates a domestic hot water (DHW) pressure fault. This typically means that the pressure in the system is either too low or too high, affecting the boiler’s ability to provide hot water.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water supply, leading to inadequate pressure for hot water production.
- Faulty Pressure Sensor: A malfunctioning pressure sensor may incorrectly report the pressure levels, triggering the E310 fault code.
Can I fix it myself? (DIY)
If you are comfortable, you can check the pressure gauge on the boiler and attempt to refill the system if the pressure is low (typically below 1 bar). However, if the pressure is too high or if you suspect a fault with the pressure sensor, it is advisable to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E310 fault could range from £150 to £250, depending on whether the issue is a simple pressure adjustment or requires replacement of the pressure sensor, which can be more costly due to parts and labour.
