If your ice tray is not freezing completely and has both hard ice and water after staying in the freezer overnight, there could be a few possible explanations for this issue:
Insufficient freezing time: Freezing water takes time, and if your ice tray is not left in the freezer for a long enough duration, the water may not freeze completely. Ensure that you are leaving the tray in the freezer for an adequate amount of time, typically several hours or overnight, depending on the freezer's temperature and the size of the ice cubes.
Freezer temperature setting: Check if your freezer is set to a sufficiently low temperature. If the freezer temperature is too high, it may not be able to freeze the water completely. Consult your freezer's manual or adjust the temperature settings to ensure it is cold enough for proper freezing.
Freezer airflow or temperature fluctuations: Uneven airflow or temperature fluctuations within the freezer can affect the freezing process. Make sure there are no obstructions blocking the vents inside the freezer that could impede proper airflow. Additionally, if the freezer door is frequently opened or if the freezer experiences power outages or temperature fluctuations, it can impact the freezing process.
Water quality: The quality of the water used to fill the ice tray can play a role in the freezing process. Water that contains impurities or minerals may freeze differently than clean, filtered water. Hard water, for example, can result in cloudy or partially frozen ice cubes. Using filtered or distilled water can help improve the freezing results.
If you have checked these factors and the issue persists, it's possible that there may be a malfunction with your freezer or the ice tray itself. In such cases, it may be worth contacting the manufacturer or a professional appliance technician for further assistance.
