What does the Ideal Vogue Max E340 fault code mean?
The E340 fault code indicates a domestic hot water (DHW) pressure fault in the Ideal Vogue Max boiler. 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 efficiently.
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 read the pressure levels, triggering the fault code even if the pressure is normal.
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, for any gas or electrical issues, it is crucial to call a Gas Safe Engineer to ensure safety and compliance with regulations.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E340 fault could range from £150 to £250, primarily depending on whether a pressure sensor needs replacement or if the system requires a refill and inspection for leaks.
