sounds like ice maker unit is faulty ,
if you take the ice bucket out and have a look at the ice maker tray ,
normal signs of ice maker issues is the tray is stuck in a twisted position
there is a mass of over flowed ice in the tray - this causes water to overflow into bucket etc .
the ice maker can be repaired quite easily , its only 2 screws and a connector plug to remove it .
