Hi Vanessa,
I have the same problem with my machine. One of the things that helps is to empty the condenser unit itself. Mine fills with water when it gets this problem and then occasionally when it gets really bad i have to shower out the condenser unit as it is full of fluff. Things still take longer to dry than they should do but I can't find the long term solution. Try these things to help you out in the meantime.
