If you notice water collecting at the back of a fridge freezer, there are a few potential causes to consider:
Condensation: It's possible that the water is a result of condensation forming inside the freezer. When warm air enters the freezer, it can condense on the colder surfaces and eventually collect as water. This can occur if the freezer door is frequently opened or not properly sealed, allowing moist air to enter.
Clogged or Frozen Drainage Tube: Many modern fridge freezers have a drainage tube that carries away the water from the defrost cycle. If this tube becomes clogged with debris or freezes, it can cause water to accumulate at the back of the freezer. This can happen if the freezer temperature is set too low or if the defrost system malfunctions.
Excessive Frost or Ice Buildup: If there is excessive frost or ice buildup on the evaporator coils, it can lead to water pooling at the back of the freezer. This can be caused by a faulty defrost system, such as a malfunctioning defrost timer, defrost heater, or defrost thermostat. As the ice melts during the defrost cycle, it can result in water accumulation.
Leaking Water Supply Line: If your fridge freezer has a built-in ice maker or water dispenser, a leaking water supply line or a faulty connection can cause water to collect at the back of the freezer. Inspect the water supply line and connections for any signs of leakage.
Improperly aligned or blocked drainage channel: Some fridge freezers have a drainage channel at the back of the freezer that directs water towards the drain hole. If this channel is blocked by food debris or not properly aligned with the drain hole, it can cause water to accumulate.
If you're experiencing water collection at the back of your fridge freezer, it is recommended to check and address these potential causes. However, for more accurate troubleshooting and resolution, it's advisable to consult the manufacturer's manual or contact a professional appliance technician.
