Why does ice form?
Every time the freezer door is opened, warm air flows inside. This results in moisture that can then condense and freeze on the interior walls despite the NoFrost technology. This layer of insulation grows a little more and becomes thicker each time the door is opened and closed. The accumulating layer of ice makes it increasingly difficult for the compressor to properly cool the interior of the appliance, thereby reducing energy efficiency. What’s more, food cannot be kept for as long and may even perish. For this reason, it is important to defrost and clean a freezer cabinet or freezer chest at regular intervals.
We will show you how you can defrost and clean your freezer quickly and efficiently.
- Clear out the content of your freezer and store the frozen food in a cool bag for the time being.
- Switch off the device, unplug it from the mains and remove the drawers.
- Open the door and place a pot of hot (not boiling) water inside the appliance. Close the door again. Alternatively, you can also use salt to defrost the ice layer. Spread some salt on the ice and leave it to take effect for around half an hour. Any remaining ice can then be removed with a plastic scraper.
- To collect the water that thaws, you can place towels or a deep baking tray in front of the freezer cabinet. In the case of freezer chests, the water can be collected using highly absorbent towels.
- As soon as the device is defrosted, it can be cleaned with water and washing-up liquid. Don’t forget to clean the seals, draws, shelves and other compartments.
- In case of stubborn dirt or unpleasant odours, a little vinegar in the cleaning water can help.
- Then wipe the freezer dry and allow the appliance to dry well.
- Insert the drawers and shelves again and connect the appliance back to the mains.
- As soon as your freezer cabinet or freezer chest has cooled completely and resumed full power, you can put the frozen food back inside.
How often do you need to defrost your freezer?
To prevent mould and unpleasant odours and other unwanted surprises, it is a good idea to defrost and thoroughly clean your freezer at least twice per year. A regular check and quick wipe-down using a cloth is advisable.
Additional helpful tips
- Food and packaging should not come into contact with the walls of the freezer and avoid overloading the drawers or shelves. This reduces the energy efficiency of your freezer cabinet or freezer chest.
- Don’t forget to check the expiry dates of frozen food often. After all, even frozen food cannot be kept forever.
- Regularly check the seals of the appliance. If the seals are defect or are no longer in the correct position, warm air will enter in these places and result in the appliance developing a thicker ice layer more quickly.
