I recently moved into an apartment with a Powermax HE 85.
When I looked up the model I saw the safety recall for the flue connector so I called them up and last week Baxi came round to change the part for free.
This involved dismantling the boiler.
However since then when we use the heating we get random lock outs with code A40 (System response fault) and some times E04 (Flow sensor open circuit). We didn't use it very much before the work, but I never saw a lockout before.
The only other difference is that before the pressure was in the range 2.4-2.9, when putting it back together the guy pumped up the expansion vessel and now the pressure shows 1.1-1.6.
Is there any chance theres something simple thats amiss with the rebuild that could be causing these errors?
