I have been unable to get the repair done, and emails have been sent and received, although I am awaiting a reply to one I sent 3 days ago. The problem is that DM Appliance Care have not been able to identify the small part that is missing from the photographs I have emailed to them. It is a small circular disc that should hold one of the prongs on the left hand internal wire structure that holds the shelves in place. I think they do not have access to a Neff parts list, and the solution has been made more difficult by their inability when they sent me pictures of parts asking me to say which one is needed. In my last email I told them "I will pay their I will be prepared to pay your call-out fee if you will assure me that it will be cancelled if the engineer is unable to mend the fault", but there has been no reply.
