Hi - our stuck has stopped moving backwards and forwards. Everything else works. We have the fault code FE-1 showing on the panel. An engineer has come to have a look and thinks it could be the SCPU or CPU controllers. Would anyone know if that is correct and where we could have them looked at in the UK. The engineer wanted to just buy a new one to test for £3000+ which is crazy money. Any help would be much appreciated.

Many thanks
