Customer Service: 0871 222 0230 try this number they sell stoves cookers and have your model.
Try their website. Many electrical manufacturers now have instructions available as PDFs.
check to see if there is a dealer in your area, and see if they can help.
if they have that model in the store, the book may be in the oven.
