Cleaning a Siemens clothes dryer

So my Siemens WT46W560FG clothesdryer stopped working. It gave an error signalling that the condensation tray was full, while in fact it wasn’t at all. Checking the internet reveals that this is a very common problem with this type of dryers, so much that it can be considered a design flaw. Siemens wanted over a third of the cost of a new machine to repair my 4-year old machine, so I said no and decided to investigate the problem myself. Turns out all is needed to get the machine running again is a (very) thorough clean. Here’s the pictures, should you be interested to do this yourself.
