Probably trapped water elsewhere in the dryer. Try the following, it worked for me. Isolate the unit (i.e. un plug it). Remover the condenser unit (it will probably be filthy with damp grey fluff - so clean it with plenty of water and an old toothbrush). Stick an old teatowel in the hole where the condenser unit was and then tip the dryer on its side.
Any trapped water should drain onto the teatowel or the kitchen floor OR it may drain into the water reservoir...anyway good luck....
