Bosch dishwasher with fault (Woolwich SE18)

Full size, stand alone white Bosch exxcel dishwasher.

It kinda works but gets stuck on the last minute so dishes come out wet and some need extra cleaning. There must be a fault which I'm not able to identify, let alone fix.

It's a great machine, has served us well for years. Will need a fix and a clean.

Collection only (I don't drive), ideally this week. Comes with all the piping, I can also throw in an extra set of wire drawers from a different model if you'd like.
