Your fridge might be making tiny or empty ice cubes mainly because of two things:

  • The temperature isn’t right

  • The water isn’t flowing well


One of the main reasons for hollow ice cubes is that the freezer temperature is too warm. If the freezer is not cold enough, the water in the ice maker will not freeze completely, resulting in hollow ice cubes. To fix this issue, make sure that the freezer is set to the correct temperature. The optimal temperature for a freezer is between 0 and 5 degrees Fahrenheit. If the temperature is too warm, adjust the thermostat accordingly.

Water Flow

Another reason for hollow ice cubes is poor water flow. If the water pressure is too low, the ice cubes will not freeze solid. To fix this issue, check the water supply line to make sure it is not kinked or blocked. Also, make sure that the water filter is clean and not clogged. A clogged filter can reduce water flow and result in hollow ice cubes.

If the water pipe is kinked or frozen, try to thaw it with a hair dryer or a warm towel. If it is kinked, straighten it as best you can.

In addition to these two main causes, there are a few other things you can do to prevent hollow ice cubes. For example, make sure that the ice maker is level. If it is not level, the water may not distribute evenly, resulting in hollow ice cubes. Also, make sure that the ice maker is clean and free of any debris or buildup.

Hollow Ice Cubes


How do ice cubes fuse together?

When two ice cubes come into contact, a thin film of water forms between them. Since the film cannot draw heat from the rest of the liquid, the region between the cubes freezes, connecting them. The water molecules from one cube bond with those from another by intermolecular hydrogen bonding.

What makes ice cubes freeze faster?

Ice cubes can freeze faster when made with hot water due to the Mpemba effect, which occurs because hot water loses dissolved gases and results in more circulation of temperature, leading to more rapid cooling. Increasing the surface area of the water in contact with the cold air of the freezer can also make ice freeze faster.

What liquid is inside steel ice cubes?

Steel ice cubes are made of food-grade stainless steel and do not contain any liquid inside. They are designed to keep drinks cold without diluting them like traditional ice cubes. Some reusable ice cubes contain silica gel in a plastic or silicone encasing.
