maybe you have an air lock in the water inlet pipe.try disconnecting it and wait several minutes, shake the pipe a bit. then connect and try again.
this happened to me once with my whirlpool fridge freezer, with water making facilities. exact same problems as you described. after i disconnected main water pipe, and pressed water button on fridge noise was heard, i connected water pipe back on and it all worked again. whirlpool were going to charge me £75 call out fee.
