Re: F 05 Error code on Hotpoint WD640
This worked for me too on the WD645 – I think this is the same model just in Silver.
Turned out the filter in the black rubber pipe had a bunch of different things in it – a number of plastic shirt collarbones as well as a bunch of buttons.
To top it off though, and what I think caused the error code – a bloody hair pin stuck in the pump! 🙂
Thanks for the advice everyone, saved me a fortune.
