I had similar problem .... on very humid days unit leaks ..... temp solution for me was to drain the unit .... inserted wire coat hanger into tube .... lots of watery gook came out.. - even tilted/tipped the unit inorder to get as much water out of it.......afterwards unit worked fine.

We are VERY SASTIFIED with the Delonghi Pinguino - bought it years ago when it first came out and it has provided years of troublefree service .... the water build up / leaking was only recently - in fact we never drained the thing until this year.

That probably is Ft, meaning full tank. Look on the bottom of the back side, and there should be a small "hatch" that will open. The two small hoses in there are drain hoses that can be unplugged to drain the tank. They're right at the bottom, so if you have a way to raise the unit up a little that would let you drain the water into a container. Might be a good time to clean the filter too.
