How can I fix my Bosch Logixx 8 washine machine?

Hello, I have a Bosch Logixx 8 washine machine, had it about 2 years now. I took the tray out to clean (strange that they get so dirty really!!) put it back in, put a load of washing in the machine, put some liquid in a plastic pot with the washing & put some softener in the tray. Unfortunately the load didn't take any of the softener - can you please help me?
Many thanks
