Hotpoint have an instruction manual download page at
http://www.hotpointservice.co.uk/Service/inst.html
it doesn't have the WD22 listed but it *does* have a manual
which claims to cover both the WD21 and WD23, and from the look of it compared to my WD22 there is probably little difference. I think this manual should answer most questions.
direct link to the download page is

Hope that helps!
