How can I unblock the condenser of my JLWD1610 washer dryer?

Don't tumble dry garments that shed fluff. It's not easy to remove. Getting a new one fitted by John Lewis authorised repairer AND changing two sensors fixed a shutting down problem (overheating).
After the repairer had gone I spent the best part of an hour trying to coax the fluff out of the old condenser using hot water and various bottle brushes to get into the nooks and crannies. Anyone want to buy a clean second user condenser? Remember you may need to buy sensors too.
