As mold requires moisture it will grow anywhere water becomes trapped, including door gaskets, filters, drawers and in hidden areas inside your machines.

The following list details a number of machines that are most vulnerable to mold development and where on those machines mold is prone to developing.

Front Loading Washers

Front loading washing machines have an air and watertight door seal that can trap moisture and dirt from clothes and offer the perfect environment for mold to grow. Mold is also often found in detergent drawers.

You can reduce the chance of mold growing by keeping the door and detergent drawer ajar when the machine is not in use.

Top Loading Washer

Top loading machines do not have the same door seals but can develop mold between the drum and the walls of the machine. This hidden mold could go unnoticed as it is harder to spot.

Once again, leaving the washer open between uses can reduce the chances of mold. Following instructions as to the correct quantity of washing powder also makes a difference as washing powder residue provides a food source.


Refrigerators are also prime spots for mold development especially in the door seals and in hidden corners and crevices. Refrigerators don’t use water in the same way as washing machines and dishwashers, but they are susceptible to condensation and thus moisture.

Regular sanitizing and wiping up any spills as soon as they occur can help to stop mold from growing.


Bits of food and water left behind at the end of the cycle make dishwashers particularly prone to mold growth. Mold can grow in the filter, the door seal, the cutlery basket and cracks and crevices inside the machine.
