Leaking tumble drier?

I have a Hotpoint Aquarius condensor tumble drier. It has recently starting leaking water from the front left corner. When we take out the condensor & tip it up, there is a fair amount of water coming out. This has never happened in the past. We have made sure it's clean inside, but think the water that it seems to be retaining may be the reason for the (small) amount of water that's leaking out of the front. Any ideas on how we can stop this? Many thanks
