I have just removed several items from the drain pump (two pencil tops (with erasers attached), three small stones, some paper, a metal link and nine 1p coins). I'm now attempting the first load. Thanks for the advice.
Just to clarify for those who are still confused. First disconnect your machine from the mains power supply. Remove panel at rear/bottom of the machine (cross head screwdriver required). This reveals drain pump (back right corner, as you face rear of machine). To release/remove pump, slide assembly to left and lift (requires a little effort). As mentioned, there will be a fair amount of water in the pump/pipes, so ensure a bowl and absorbent cloths are to hand.
Unscrew two Jubilee clips and three further screws (requiring Allen key).
Clear debris, flush pipes and reassemble.
