Hi Jeanette. I had the same problem recently and managed to fix it for 79p. Don't laugh at my technical knowledge but....I undid the handle, took the big clear plastic thing out and underneath it was a blue, flimsy film like thing which was torn. I took it with me to Wilkinson's and found another blue thing (threw the packing away and can't remember what it was called). I replaced the old one with one of them and put the whole thing back together again (having made a note of where everything went whilst undoing it). No more probs!
