2E (207) - Heating system charge pressure is too low

What does 2E mean?

This error indicates that the water pressure within your boiler's heating system is below the required operating level. This low pressure can prevent the boiler from functioning correctly.

• Insufficient water in the heating system
• Leakage in the heating system
• Faulty expansion vessel
• Pressure gauge malfunction

Click steps to track your progress.

1. 1

   Check the pressure gauge on your boiler. If the indicator is below 1 bar, add water to the heating system until the pressure is between 1 and 2 bar.

2. 2

   Inspect all visible pipes, radiators, and connections in your heating system for any signs of water leaks. Even small leaks can gradually reduce system pressure.

3. 3

   If you frequently need to top up the water, have an installer check the expansion vessel and the entire heating system for hidden leaks or issues.

4. 4

   If the pressure gauge appears stuck or inaccurate, it may also be faulty and require professional assessment.
