Washer Dryers work by having cold water trickle down the inside of the drum whilst hot air is being blown into it.The hot moist air from the washing converts back into liquid when it hits the cold water, and it is pumped out along with any fluff that may be with it. Unfortunately the internal ducts and channels get congested because of this fluff and prevent the cycle being completed. The condenser needs to be removed and cleaned out thoroughly and so does the sump and outlet hose. Another cause of drying problems is if the cold water is not getting through, so check the cold water supply from the valve. Washer Driers have a triple valve on the cold side, one is for the wash powder and rinse, one for the fabric conditioner and one for the condenser.
