I'm trying to figure or if there is a trend with certain model fridges where the water fill tube either leaks water, which is causing the freezing, or if there is some sort of defrost mode that is supposed to prevent the fill tube from freezing. When it does freeze, the tray is impeded by the frozen water and the tray doesn't turn as much as it should, thus creating issues dispensing the ice bites. The regular ice cubes are perfectly fine.  The model I have is RF29A9071SR. Not sure if it's part of the Bespoke series fridges.
