E 118 Fault, Low system pressure. How to top up / Repressurise Baxi EcoBlue Advance Combi Boiler

1. Check the pressure on you boiler (normal pressure is between 1-2 bar), if the pressure drops to 0 will show E118 fault code.
2. If the pressure is below 1.5 bar, you can top up by using the filling loop, in this case is an internal filling loop with two blue leavers. You have to open booth blue leavers valves one by one and keep open until the pressure reach 1.5 bar.
3. After the pressure reached 1.5 bar you have to close booth blue leaver valves, one by one.
If you didn't manage to close on time and the pressure is above 2 bar don't worry, you can just bleed a radiator and then the pressure will drop automatic. If the pressure is above 3 bar, then the boiler Pressure Relief Valve (PRV) will open and will discharge the water trough PRV pipe and the pressure will drop automatic.

Glad it was helpful!

Don’t really have the blue taps, basically no filling loops. Only the black ones. What now?

Please send a picture from the pipes and valves under the boiler and I will try to help you.
