I recommend to soak the bottom of the brush in a cup of warm water to make it easier to remove the bottom cap. The plastic is very easy to crack when cold.

This is a decent guide. Thank you to the author! Problem is that they don't make these devices user serviceable, so we basically have to pry and force the cap off. ARGH! RIGHT TO REPAIR NOW!!
