Just had a quick read through the manual, which you can find here: https://www.samsung.com/uk/support/model/RSG5UUMH1/XEU/
It offers these suggestions:
• Is the water line connected and the shut-off valve open?
• Did you manually stop the ice making function? Make sure Ice Type is set to Cubed or Crushed.
• Is there any ice blocked within the ice maker bucket?
• Is the freezer temperature too warm? Try setting the freezer temperature lower.
Let us know how you get on.
