Ariston CD12T Washer Dryer does not dry?

Just moved from USA to Ireland. Apartment has this Ariston CD12T washer-dryer. Its small, and washer works fine, but the dryer does not dry clothes. Clothes get VERY hot and steamy, but never get dry. And, the water is turning on every minute or two while its in the dry mode...? How are clothes supposed to get dry with the water turning on? We're on the top floor of an apartment building, and we have a water pump to supplement water pressure. This pump turns on every minute or two while the dryer cycle is on. What is going on?!? Please help!
