Kitchen Aid frig internal water dispenser--1 touch produces over 68 qts of water. Help! 24 hrs old!

I've had my Kitchen Aid refrigerator for 24 hours. Twice we have used the internal water dispenser; both times one light touch produces over 68 quarts of water. This is ruining my wooden floors and food inside refrigerator! I've turned the water off now, but won't have any ice until this is repaired or replaced. What causes this? What can I do? Help! Thank you!
