Condenser unit on Hotpoint CTD80 not collecting water?

Have noticed there is no water in the condenser unit for the last few weeks, clothes are drying fine. Pulled dryer out and there was some water coming from the unit but not loads. Is there a blockage, how could I fix it or shall I just invest in a new one. Unit is 2 years old, bought a 5 year warranty for it but the company has gone into liquidation.
