MAC 10K purchased 7/19/06 Unit has worked well for two years. Because of the high humidity the cooling unit would shut off after about 2 hours use and I would have to open the drain plug to remove the excess water. This summer the unit has begun to continue to run with water leaking from the front and side on the bottom. When I open the drain plug, very little water comes out. If I tilt the unit toward the drain plug, a large quantity of hot water pours out.
