baxi duo-tec combi 33 he a

[roxey64]

hi i have the baxi duo-tec combi 33 he a boiler.
i have been getting the same error code for a week each morning and losing all pressure then having to top up each morning to get warm.
once topped up the boiler fires up fine.
Noticed water dripping from the pipe out side.
removed the front cover and plate( expansion tank is on the left hand side of boiler but on its side), is it easy to check tanks pressure, ie easy to get out if so what pressure should it be? thank you in advance

The FAQ on this site will give you the information.

However, I dont think a DIYer should be opening the cover on your model as its the outer combustion chamber cover.

ok slapped hand here, i will close it and call a plumber, i have re pressurized this chamber in the bast on my old boiler and replaced parts, nothing to do with the gas parts as i do alot of plumbing with my work, but your advice suggests this could be dangerous thank you for your input
