The problem of hollow ice cubes can be caused by low water pressure to the fridge.
If the temperature in the freezer is not cold enough this can also cause hollow cubes.
If you have had this fridge for a few years with no trouble my guess would be the saddle valve.
What happens with the saddle valve is mineral build up in side the line where the piercing valve goes through the line.
Installing a regular pluming tap type valve may fix your problem. |
