Heya Debb,
I might not be the right person to answer this since I haven't received mine yet. But I have heard mention of a similar problem where a user inadvertently had the slots in the carto covered up by the o-rings so the liquid wasn't actually able to get into it. It might be worth a shot to make sure you can see the slots through the tank.
