Beko WDC7523002W washer dryer clothes hot and damp after drying cycle

As per the topic title. Heater and fan both ok, and condenser and heater duct not obstructed. Water delivery to the condenser seems to be the issue. The condenser inlet valve has continuity, is energised (mains voltage across it) and delivers water for about 1 sec(max) at one minute intervals. I’m guessing that water delivery should be more frequent/constant, and that this is likely to be a faulty main module. I have a spare module BEK2437301301 which is the one used in the integrated washer dryer. This is a FS machine but the only difference I can see in the modules is that the ‘foot’ of the case is shorter for the FS version. Questions are: Is the board the same? Is this, as I am guessing, a board fault? Any comments gratefully received. Derek
