Cleaning the drain pump of my washine machine - I want to, but DS says Noooo!

[LineRunner]

I mean, how hard can it be? DS (14) says, Get the repairman out. But I've got the destruction book, and I want to have a go.

The machine won't drain or spin since washing a cheap red Asda throw which seems to have disintegrated inside the machine - it's likely bunged up the drain pump? (Thanks, Asda.)

Anyway, what can go wrong? ??!!

thanks, Boooooyhoo. Gotta keep
