Did a quick search and found someone had a similar problem here-http://www.howtomendit.com/answers.php?id=134938

it seems that if the pressure is ok then you should check the plastic pipe for escaping condensing water, it must be below the condenser and have no loops in it (you should follow the above link and read the posts there for an accurate description)
