Proline TDC75 condenser dryer

(This dryer is a whirpool style)I have been to this dryer recently, fault leaking and noisey.
1/ Replaced door seal as it had a split in it and water was collecting inside the split and then dripping down the front onto the floor.
2/ unblocked the rear fan full of dog hair.
3/ Removed jockey wheels /rollers and cleaned.
4/ Drain hole clear and filling container

It is positioned in the kitchen infront of a radiator.
Seems to get very hot in drum!
I think the front fan is vibrating causing the noise.

Customer has called back to say its still leaking.
Could this be condensation and if so any ideas.

Regards
Steven
