What causes fridge condensation and how to fix it

If you've noticed water pooling at the bottom of your fridge, or you're concerned about a build-up of condensation, don't worry - we'll tell you why it happens, and how to get rid of it.

Most fridges are designed to deal with a small amount of condensation through a drain at the bottom of the fridge cavity. But if you're starting to notice more water than usual, there are a couple of things you can do.


Drainage problems

There are a couple of things to look for if water is pooling at the bottom of your fridge.

Unblock the drainage hole

The first thing to check is the drainage hole. You should find it at the back of the fridge at the bottom of the back wall.

Fridges are designed so condensation can filter through this hole into a small pan that sits on top of the compressor. The heat from the compressor then causes the water to evaporate.

Problems can happen when the drain gets blocked. Try cleaning it with something like a pipe cleaner, or cotton bud, making sure any blockages are removed.

Check for ice build-up

Sometimes, ice can build up on the back wall of your fridge. This can be caused by the fridge being overfilled, preventing air from moving around and keeping the fridge frost-free.

If ice builds up, this can stop water from draining out of the fridge. The only way to fix it, is to de-ice the fridge by turning it off and letting the ice melt.

Once the fridge is free from ice, it's a good idea to check the drainage hole to make sure it's clear before turning it back on.


Fixing condensation problems

When you open your fridge door, warm air rushing in can cause water droplets to form on the back wall or ceiling.

Here are a few things you can do to keep condensation to a minimum:

# 1. Make sure food is at room temperature or lower before putting it in the fridge.

#2. If your fridge isn't level, water won't flow to the drain correctly. Raise the front floor screws by a couple of turns to change the level of your fridge.

#3. Make sure the door closes properly and the rubber gasket forms a complete seal? To test this, try closing the door on a sheet of paper. If you can pull it out without a problem, the seal could be too loose and may need replacing.

#4. Make sure your fridge temperature isn't too high (or too cold). It should be set between 0-5°

#5. Always close the fridge door as quickly as possible after opening it. Leaving the door open allows warm air to enter and increases the possibility of condensation.

#6. Make sure your fridge is clean inside and out. Give the door seals a good wipe down to make sure they're making proper contact with the fridge. Get the WPro Fridge Care Kit to help keep your fridge in tip-top condition.
