Looking at th eonly manual I can find (http://imagebank.indesitcompany.co.uk/brochures_online/pdf/Creda/Dryers/HBTCR13.pdf), the nearest thing I can see to your "receptacle" is the water cointainer that slots in at the bottom of the drier.
Thirty seconds with aGoogle search is all it would have taken you to find things like this:
