A blockage in the drain tube is one of the most common culprits of water leakage. This is caused by small debris or particles that clog up the drain hole, not allowing a proper channel for the water to pass through. An easy fix is to turn on defrost mode and unblock the drain tube to allow the water to escape. Please make sure to remove any power cables attached to your freezer before attempting to unclog it to avoid potential shocks or accidents.
