    Hi,

    The pressure on my boiler is low and has error E118.

    I don’t see any filling loop under the boiler but there’s is one near the unvented indirect cylinder.

    Does anybody now how I guy about adding pressure?

    thanks . image.jpg

    you will have a filling loop flexible hose somewhere, remove the cap and place it between the valves as shown, open both valves till pressure is between 1.0 Bar and 1.5 Bar, then close both valves and remove the hose again and refit the blanking cap
