Does this Buderus GB142 -60 Heat Exchanger Have An Internal Leak? Pics of Exchanger Inside.

in THE MAIN WALL
Bought this house recently. The boiler today had a no fire code. When I looked at it, the condensate drain was completely plugged. When I unplugged it, I'm guessing a quart of water came out. It now fires fine after draining, but I thought I would check out the heat exchanger.

The boiler is approx 10 years old. It looks like it has never been cleaned, so I will be doing the multiple mineral oil cleanings to get this thing looking better.

However, I'd like to know if the amount of condensate in here is normal for a 10 year old boiler that hasn't been cleaned, or is it an indicator that the heat exchanger has a leak? Also the amount of water that came out of the boiler when I unplugged the drain seems excessive. However I cannot see any damp areas in the heat exchanger.

Thanks in advance!

    That looks typical of a neglected GB-142. The reservoir looks recent so it could be a sign of lack of maintenance because that plastic doesnt last long without it. The ignitor and flame sensor are probably fairly new as well, and it might be fair to say it's the only time it's been opened up in 10 years.
    Get new gaskets.
    Like @lchmb said, it definitely needs a combustion test.

    Normally they leak between where the side water ways connects to the heat exchanger. You don't see an leak , you should be good

    There was an error rendering this rich post.

    Axiom's AXI-Therm CLEAN F9A & F9B does a great job of cleaning this "moon rock " off the combustion side of the heat exchanger. I did mine a couple years ago after 9 years of buildup. See the link below on the Axiom website.

    Not sure if you have the manual so here it is. It only states : Inspection
    We advise you to offer your customer an annual inspection and
    maintenance contract (for the contents of this contract,  page 35 and page 35).
    If inspection reveals that maintenance work is necessary you can carry this out as required ( chapter 12 “Maintenance”, page 29).

    I think it should be a little firmer, all condensing units should, I've seen many cases where people have gotten CO poisoning or died due to a lack of maintenance.
