Re: servis appliance
judging by your query, it’s outside your comfort-zone to open it up and have a look.
I’d suggest you look at the “find an engineer” function on this website(may appear under this post1 🙂 This will help you locate an independent local repairer who won’t rip you off.
Although Servis has gone, it’s likely the electrical/electronics bits were all bought in from outside manufacturers,which would mean that new elements, controllers and the like will probably be fairly easily obtained…it’s also possible that they are “standard, off-the-shelf” parts.
don’t write off the possibility of repairs, just yet…..in future you may struggle with pan-supports,control -knobs and the like.
