    Hi,

    So I tested the boyler like this:
    - pressurised the system to 1.5bar and closed the valves from right underneath on the main and return.
    - turned off the boyler and put the condensate discharge pipe in a bucket

    Sure enough the pipe drips slowly with the boyler off and the system pressure drops slowly.
    When running normaly the pressure drops below 0.5bar in 1-2 days.

    Does this mean that the heat exchanger is cracked and need replacing or maybe it's possible that some o-ring is faulty? Anybody who had the same problem and fixed it please give me some hints on how to troubleshoot this further.

    Thanks

    Try and get a Baxi fixed price repair , will be half the price of buying a new heat exchanger
