Thanks Gary! It looks as though that solved the problem! I took off the lower plastic back panel which has the drain tube coming through it and could clearly see the black rubber concertina pipe and pump attached to it. I undid the large jubilee clip (using a posidrive screwdriver) on the rubber pipe and inside was a load of mush - several clothes labels, hair etc around a small plastic cradle and ball. I emptied the mush and replaced the cradle redid the jubilee clip and back panel. The whole procedure took about 10 minutes to do and probably saved me £100 for a call out!
