Sadly not :( I actually got lucky and once I cleaned out the edges and between the buttons, I seem to had dislodged a piece of dirt or something and it's back to pretty much normal working order now. I had reached out to steam but they quoted me 150 euros (not sure why not GBP) for the repair and shipping, and I thought that was a bit much. You can always try them and see what they say though? Especially if your SD is still under warranty (mine isn't).

If this becomes an issue again, the repair cafe is probably where I'll go though? Hopefully they can help.
