    Hi, today I removed plate heat exvhanger and washed, but when I assemble plate heat exchanger back, there is always powerful water leak form right part(exchanger), even I think screw is secured, any comment about the reason?

    Thanks in advance!

    Have you put any grease around the seals when installing?

    I assume this is on your Baxi duo Tec.

    It looks like a crap design just 2 Inboard screws on the heat exchanger to hold it up against the 4 o rings on each corner.

    I'll take your word it's a difficult job, I don't really touch boiler internals.

    I tried to repair my old boiler as the o rings were leaking on the heat exchanger, but after spending 2 hours trying to get the pipes out I have up before I broke it completely, ended up getting a new boiler

    Yes never re-use old seals.

    When you reinstall them put some grease around it to help it seal
