If you have ever felt that your washing machine smells, then you are most probably right. It can be damaged and smell just like any other home appliance. In fact, the smell can to such an extent that it can be as horrendous as that of a sewer. Now while the task of a washing machine is indeed all about cleaning, it does gather dirt and debris of all sort while the washing of clothes takes place. So, the smell may not be there instantly, but it can most certainly develop over a certain period of time.
But it's not always just the dirt from the clothes that can cause the smell. There are a couple of other reasons as well, which you may not have expected. The various reasons can include plumbing, temperature, detergent dispenser, heating elements and so and so forth.
If your washing machine is not causing any smell yet, you can take necessary measures in advance to stop it from happening. For instance, you can avoid setting your washing machine at a low temperature. While there's evidence that low temperature saves energy, but it is also a contributor to nasty smell. You should also keep an eye on other parts as well, such as the drum and the seal.
The basic solution is, of course, to make sure your washing machine is clean and tidy. The infographic below sums up the reasons behind a smelly washing machine, along with a few tips on maintaining its neatness.
