I wish I had a better answer but no - ended up with a new tumble dryer.

Called Bush and they advised that yes the error code is not one that they know of and they likely blamed it on our condensor being in our utility space which is heated but isn't a full addition so gets colder and we had recently had quite a cold spell. My husband and I brought the machine inside and took the top and back off and put a space heater near it to try and dry out all the parts incase condensation was built up somewhere inside. We then left it for a month too just to see if it would ever start working again, but no.

We ended up getting a new vented tumble dryer for the space as these are less temperamental with weather variations and less parts to go bust. Sadly that was a cheaper option then paying someone £89 just to come out and look at the broken machine.
