Dawoo Fridge Freezer Model No FRS-2031IAL?

The ice dispenser is freezing up, the whole of the ice tray is a solid block of ice. On investigation the ice compartment was solid block of ice and also I found a small plastic item that seems to have broken off some where . I have turned off the water mains in order to stop any further problems. There also seems to be water coming from the very bottom right hand corner of fridge, could it be water thawing from collection tray ? & lastly due to these problems all of the components ie small wires etc have all frozen icicles.
