Is There Mold in Your Appliances?

Mold is almost impossible to avoid. Any place moisture can be found mold can grow including inside our houses and our home appliances. All in all, over 1000 of the 100,000 known species of mold have been found in US homes.

Because mold likes to breed in wet places home appliances that involve the use of water are more susceptible than most to mold, as are fridges or ice machines where condensation occurs as the warm and cool air meet.

The last thing you wants is mold growing inside, and even more so not in home appliances that you are using to wash your clothes or dishes or store your food. Not only is mold unattractive but it can also make you unwell, even more so if you have a mold sensitivity or have underlying health conditions such as asthma.

Health implications differ from person to person and on the species of mold, but can include sinus irritation, coughing, migraine, an irritated throat and skin irritations. Sinus and digestive tract infections can also occur by mold spores and are most common for those who have underlying health conditions.

Luckily, according to Pure Air North Carolina in Charlotte, there are a few simple steps you can take to keep your home free of mold and safeguard your health and the effectiveness of your machines.

Why Mold Grows in Appliances

Mold is naturally occurring and breeds pretty much anywhere. The places we live offer an ideal environment for mold proliferation due to the fact that molds thrive in the same temperature range that people do. As well as the perfect temperature, our homes provide water and organic matter.

Moisture as well as the fact that many appliances in the home use water is one of the key factors that make home appliances vulnerable to mold development, this is made worse by ventilation and high levels of humidity. Not letting appliances completely dry out after use will result in mold growth, but, drying appliances completely can be difficult and mold only needs a small amount of water to grow.

Mold also prefers darkness, making the the areas inside or behind home appliances are ideal hiding places for mold to develop.

Finally, mold has to have a source of food which can be pretty much any form of organic matter from dust containing dead skin cells to scraps of food in the bottom of the dishwasher or the food and spills in the fridge.

Keep your appliances mold free is easy enough. You do however need to be aware of the conditions mold requires to grow and not forget to clean hidden places regularly.

Where Mold Grows in Home Appliances

As mentioned above mold breeds anywhere there is moisture, and in the case of home appliances this often means anywhere water becomes trapped and cannot fully dry out between uses.

The following list details some of the machines that are most susceptible to mold growth and where on those machines mold is most likely to develop.

Front Loading Washers

In a front loading machine, mold will often breed in the door gaskets and the detergent drawer, as water gets trapped in these areas between uses.

You can limit the chance of mold taking hold by leaving the door and detergent drawer ajar when the appliance between uses.

Top Loading Washer

In a top Loading washing machine, mold will often develop inside the machine between the drum and the inner wall. This hidden mold could go unnoticed as it is harder to see.

Once again, keeping the washer ajar between uses can help the machine dry fully between uses. Following instructions as to the correct quantity of washing powder also makes a difference as washing powder residue provides a food source.


Fridges are also very susceptible to mold proliferation with mold often growing in the door seals as well as on old food. Refrigerators don’t use water in the same way as washing machines and dishwashers, but they are susceptible to condensation and thus moisture.

Keeping your refrigerator clean is the best place to start to prevent fridge mold.


Bits of food and water left behind at the end of the cycle make dishwashers especially prone to mold proliferation. With dishwashers, mold can grow in the filter, the door gasket, the cutlery basket and the interior walls.

Ensuring any remaining moisture can evaporate by leaving the door ajar and removing any food waste regularly can help prevent mold.

Checking for Mold in Your Home Appliances

In most cases mold will be visible in your machines. Regular checking of the door seals for any discoloration, spots or obvious mold development is good practice, as well as any other spots that mold may hide.
