Piece fell off

This lens fell off my machine. I have no idea where it goes

That looks like one of the side windows, either on the head or underneath the left side panel.
They screw in.

You can see where they go when you read through the cleaning instructions here:


Thanks for your quick reply. My life flashed in front of my eyes

Mine fell off once, but then got scratched on the track. I now check it when cleaning. :slight_smile:
