This is part two of a look at what causes smells from a washing machine and how to get rid of them. The first part looks at problems inside the washing machine (what causes washing machine smells?) but this one looks at smells coming from the plumbing that may be blamed on the washing machine. There’s a link to the first article at the bottom of this one.
Common general problems with washing machines
This is a category list of all my articles related to general washing machine problems (not breakdown faults). The articles cover a wide range of issues that can affect most washing machines so it's well worth browsing through them. You might be surprised how interesting or useful some of them are.
If your washing machine’s drum is covered in a greyish white coating it is probably caused by limescale. To remove it try adding about 20 gram of citric acid into the machine and wash on a 90 degree wash cycle with no laundry inside. You may need to try it more than once.
Black mould is unpleasant, and potentially hazardous to health. It is caused by having conditions where the airborne spores can survive and thrive. It thrives in damp places. Using more hot washes and detergent which contains bleach will help prevent black mould. They also help kill bacteria that can otherwise multiply inside a washing machine. Many "colour-friendly" detergents and all liquid detergents do not have any bleach in them which is why they are "friendly" to coloured garments.
This page looks at the effects of hard water and limescale in washing machines and plumbing. Limescale removing products are just dealing with symptoms and not causes. After research, I’m writing about limescale and hard water, in a non technical way and looking into water softener products.
Causes of grease, slime and black mould inside washing machines
This article looks at the importance of a maintenance wash using the hottest program, and how to get rid of mouldy, musty or bad smells from washing machines. It also points to the causes so as to protect from the problem in the first place or prevent re-occurrence. A washing machine covered with gunge and grease inside can also cause marks on laundry especially if laundry gets dragged round the rim of the drum and picks up grease from under the door seal.
