Gtbarringer I can’t see evidence of water anywhere else? In the photo I see a screw, bottom right, hopefully it is the Gicar mounting screw, or perhaps an extra, in any case fish it out.
I have never known a pump case split or leak…but I am wondering if it could be coming from the white push on connector? My conclusion is because, you said it was tripping out, which in the case of a leak like that, I can’t see anything that would trip it…unless it was spraying out. If it was coming from above, then sure..but I checked the other photos and I can’t see anything obvious above.
Yiou are of course dismantled to the point where a vibration pump change is relatively easy and the way you have stripped it down shows you will easily be able to do that change…it’s just I’ve never heard of such a problem….so have a look at that white connector on the right and for any evidence of water coming from above.
I’m not saying it’s impossible for a pump not to leak from the case….just in over 18 years I’ve never seen it.
