Why can't I close the brewing unit on my Bosch Tassimo JOY TAS4502N?

If you're unable to close the brewing unit on your Bosch Coffee Maker, ensure the piercing unit and T DISC support are correctly inserted. Press the piercing unit into its holder using both thumbs and check the position of the T DISC support. Also, check that the T DISC has been correctly inserted or replace the damaged T DISC with a new one, placing it with the printed side facing downwards so that the tab is resting in the intended slot. Finally, clean the brewing unit with a soft, damp cloth, paying particular attention to the lid area, and press the lid down until it audibly clicks into place.
