Hotpoint WD240 Locating Condenser

[Reg6961]

Going round in Circles. Hot wet clothes after drying cycle.
There is an aluminium duct at side top of machine that contains heater and fan. Heats up O.K. and fan rotates freely. Not clear whether this is condenser as no water supply to it that I can discern. Hence condensation must take place elswhere. But where?

depending on the serial number, on the back of the heater box is a grey pipe on the heater box underneath that is a fluff filter that needs cleaning and check the valve is working it should give short spirts of water into the mc to clean the filter.

I have attempted by these two photos to show my configuration.
There is a grey corrugated pipe.Is this the one that washes filter?
I have lifted off cast Aluminium housing which contains heater and fan.No large fluff deposits but no signs of a filter.If there is one it must be in the bowels of the casting off the drum.
Seems next step is to see if water comes out of the small grey corrugated pipe.
Thanks so far. Any other thoughts given the pictures?
