Why is domestic water discharging from the 7 bar valve on my Gabarron CM15 Boiler?
If domestic water is discharging from the 7 bar valve in your Gabarron Boiler, it means there's excessive pressure in the domestic water system. Check that the incoming mains pressure is below 5 bar. Consider fitting a pressure reducing valve. Also, verify that the 2L expansion vessel is charged with air.
What to do if Gabarron CM15 displays fault E3?
If your Gabarron Boiler displays fault E3, it indicates a problem with the heating system water flow switch. This could be due to low heating system pressure. Check for leaks and refill the heating system to 1.5 bar.
Why is my Gabarron CM15 heating system discharging water from the 3 bar safety valve?
If the heating system water is discharging from the 3 bar safety valve in your Gabarron Boiler, it indicates excessive pressure. Ensure the filling loop is not passing water and remove it. Check that the expansion vessel is charged with air, and verify the system expansion volume.
