Why Does My Washing Machine Smell? 5 Ultimate Steps Guide

Buildup of Bacteria

A washing machine is meant to clean your clothes, but it might not be doing its job if it starts smelling. The smells of a bad washing machine are typically caused by a buildup of bacteria and residue not cleared from the wash cycle. This can lead to poor drainage, mildew, mold growth, and a foul smell that can linger in your laundry room.

If your washing machine smells like sewage, there could be a clog in the drain line that allows water to be trapped and produces hydrogen sulfide gas. This odor is similar to the smell of rotten eggs and can be quite unpleasant.

If you’re experiencing this problem, the first thing to do is turn off your washer and open a window in the laundry room. Next, remove the washing machine from its stand and inspect the hose and drain pipe for a clog. You can use a drain auger or snake to clear the clog if it is found.

If you don’t see a clog, try running a hot water cycle without any detergent or fabric softener to clear any residue from the machine. If this does not work, it might be time to call a plumber.

Limescale Buildup

Limescale can cause a number of problems, including restricting water flow within your home and making it harder for appliances to work effectively.

This can lead to them breaking down, requiring them to be used more frequently and costing you more money. Fortunately, there are some simple steps that you can take to deal with this problem.

You should make sure to use High Efficiency (HE) detergents as these help to minimize soap scum buildup. It would help if you also ran a maintenance wash regularly.

This high-temperature empty wash program cleans and sanitizes your washing machine. In addition, you should regularly clear your stand pipe to ensure that a buildup of residue doesn’t block it.

Unlike detergent and fabric softener residue, which can be flushed away with rinsing water, limescale deposits must be scrubbed off with acidic solutions. This includes various commercial descaling products and household substances such as lemon juice and vinegar.

Vinegar is a great choice as it contains acetic acid, which can dissolve these hard deposits. It would help if you sprayed the inside of your appliance with this solution, paying particular attention to the rubber seal where deposits tend to be found.

You should leave the vinegar in contact with the mineral deposits for at least 30 minutes before scrubbing them off with a sponge or brush.

Dirty Seal

The seal around your washing machine keeps the water and detergents inside, but it’s also a place where bacteria can thrive. A foul smell may develop if you don’t clean your washer regularly.

This can be caused by a buildup of soap scum, dirt, lint, and other water minerals, as well as the residue from laundry additives such as fabric softener.

A foul odor can also occur in the drain hose or standpipe, which could be clogged with hair or other debris. If you suspect this is the issue, remove your washing machine from its pedestal and turn it off before cleaning it.

Put on gloves and carefully inspect the hose and standpipe for blockages. If you can see any clogging, use a drain unblocker to clear it.

If you’ve done all this and the smell persists, it might be time to call in a professional. The rotten egg or sewage smell could indicate a serious plumbing problem, such as a blocked drain or backflow, which would require a plumber to deal with.

The easiest thing you can do to prevent a smelly washing machine is to ensure all the components and dispensers are fully dried after each wash. This will help the bacteria and limescale get flushed away with the rinsing water and keep your clothes fresher for longer.

Plumbing Issues

When soap scum, detergent residue, water minerals, and lint accumulate in your washing machine, they provide a breeding ground for germs to thrive in. Over time, this can lead to a foul, musty odour, and it’s especially common in front-loading machines. It’s a good idea to clean the seal, detergent drawers, and any area inside your washer that can be reached regularly to prevent this from happening.

If the smell coming from your washing machine is reminiscent of a sewer, this may indicate that the appliance has a problem with its plumbing. Depending on the severity of the odour, you could have a clogged drain or a faulty gas line.

Either way, this is a serious issue that requires immediate attention as the presence of hydrogen sulphide can be dangerous to your health.

If you’ve noticed an unpleasant odour coming from your washer, there are several home-made and professional solutions to try to rid your washing machine of the odour.

However, it’s important to remember that a stinky washing machine is often the result of mildew, bacteria, or other odour-causing buildup and should be cleaned regularly to prevent this from occurring.

If the odour persists, it’s best to consult a professional plumber to ensure the issue is addressed immediately. Charlie Elizabeth Culverhouse is a journalist at Goodtoknow, specializing in family content.

Conclusion:

In conclusion, a smelly washing machine can be a nuisance, but understanding the common causes can help you address the issue effectively. Bacteria buildup, limescale deposits, dirty seals, and plumbing problems are the usual culprits.

Regular maintenance, such as using high-efficiency detergents, running maintenance washes, and cleaning seals and dispensers, can prevent unpleasant odors. If your washing machine continues to smell despite these efforts, it may indicate a more serious plumbing issue that requires professional attention.

By following these tips, you can ensure your washing machine remains clean and fresh, providing you with spotless laundry every time.

FAQs:

Why does my washing machine smell bad?

Answer: Washing machines can smell bad due to the buildup of mold, mildew, detergent residue, or trapped lint. These can create a breeding ground for bacteria, leading to unpleasant odors.

What causes mold and mildew in washing machines?

Answer: Mold and mildew thrive in damp, dark environments. Leaving the door closed after use, using too much detergent, or not cleaning the machine regularly can contribute to mold and mildew growth.

How can I prevent my washing machine from smelling?

Answer: To prevent odors, regularly clean the machine, leave the door open after use to allow it to dry out, and use the right amount of detergent. Also, run a monthly maintenance wash with hot water and vinegar or a commercial washing machine cleaner.

Can the type of detergent I use cause my washing machine to smell?

Answer: Yes, using too much detergent or a detergent that doesn’t rinse well can leave residues that attract mold and bacteria, leading to odors. Using high-efficiency (HE) detergents in the correct amount can help prevent this.

Is it necessary to clean the washing machine filter to prevent odors?

Answer: Yes, the filter can trap lint, hair, and other debris, which can become smelly if not cleaned regularly. Check your machine’s manual for instructions on how to clean the filter.

Does the type of washing machine affect how likely it is to smell?

Answer: Front-loading washing machines are more prone to odors due to their design, which allows water to get trapped in the door seal and other areas. However, top-loading machines can also develop smells if not properly maintained.
