Be careful; it's dangerous climbing around up there; but that is the best place to start. Check the condition of the cap, seal (mine looks like cork), the caulking around the inner and outer rings and make sure the little "weep-hole" is open.
From looking at mine, I don't see how water could get in unless the cap is cracked. Otherwise, when closed, the seal should be pretty good, and the "weep hole" in the outer ring should take care of any small amount of splash that does get in around the outer lid.
You're not the first with this problem, however. Let us know how it checks out.
