Is there an air leak, too? Water that is introduced into a GCMS, like after cleaning or column replacement, is pumped away quite quickly. It may take ten to twelve hours, but it will be gone. Now water introduced by the gas from the GC is a different story. If there is water in the carrier gas or coming from, say, a purge and trap or a hydrogen generator, it may never go away. That is a clue to help you find the source of it.
If there's air as well then you need to look for that leak first.
