Year old unit. Generally is still spotless, though some corrosion noticed at bottom rear interior. Pics below. Anybody encountered a similar issue?

    Looks like it gets a little damp now and then, but I see nothing really out of line...

    Doesn't look too bad. I would check the venting and make sure its 100% done the way the installation manual states. I see a lot of condensing boilers having moisture problems due to flue gas recirculation.

    it's fine--probably happened a year ago. Those plastic air vents are atrocious, they will leak at some point down the road.

    Is it dripping from the bottom of the HX...We have seen some of the WB2B and HA series that had concentric venting system regurgitate on the termination just to bring the condensate back to the cabinet, drip onto the top of the HX,follow the circumference of the HX and the drip onto the wiring harness of the gasvalve...The control console and wiring harness would then need to be changed. 😔

    OK thanks all. More investigation required to find out exactly where this leak originates.
