WT741 Hotpoint 7KG Ultima Fault F-05?

I have just moved house, bring my Hotpoint Ultima WT741 with me, I have only had it about 4-5 months. Because I have just moved I have packed the manual, and can't lay my hands on it, but don't know why the drum won't empty the water and it keeps flashing F-05 at me! I assume its a problem with the empty cycle but don't know how to fix it!
