Bought this for my son for Christmas wanting to make homemade ice cream.  We've done several batches of different kinds and they've been great over the last 1.5 years. We've followed the manual to the 't' (cold, overnight chilling of liquid, room temp before we wash it and completely dry before putting it in the chest freezer in it's special spot). But recently it started leaking the blue liquid.  Very disappointed in the KitchenAid manufacturing on this one for the money :(
