Causes of grease, slime and black mold inside washing machines
Smells Washing machines appliance now commonly suffer from a build up of a greasy deposit and bacteria which causes bad smells, rots hoses & door seals and blocks the pressure system causing overfilling or spin failure. An even more serious consequence of this problem is that the aluminium based drum spiders can be corroded by the build up of grease and gunge, which can cause one or more of the drum’s arms to break. This is often fatal to the washing machine appliance.
Rotted drum spider this problem was virtually unheard of before the 1980s but when detergents started to become more environmentally “friendly” and liquid detergents were invented this issue suddenly appeared. It seems that the problem is worse when a combination of factors are involved, but almost everyone suffering the worst cases of this slimy grease uses 40 degrees washes almost exclusively. This, combined with either poor quality detergents, not using the recommended quantities, or only using colour-friendly detergents or liquid detergent which contain no bleach allowing bacteria to thrive can seriously rot a washing machine appliance inside.
