So, whether you have an old model or a state-of-the-art appliance, follow these tips that will help you get your pipes smelling fresh and clean in no time.
Where do sewage smells come from in the washing machine?
Laundry and detergent residue
One of the most common culprits is build-up of laundry detergent, detergent and fabric softener residue in the washing machine. These residues can trap moisture, dirt and bacteria. This creates an environment conducive to the growth of bad odors.
Molds and bacteria galore
L’persistent humidity in the drum of the washing machine can encourage the proliferation of mold and bacteria. These micro-organisms then release smelly gases which spread to your clothes during washing.
Clogged pipes and siphons
Your home’s drains connect to the washing machine through pipes and traps. If these ducts become clogged due to debris or residuethey can cause unpleasant odors to come up in the washing machine.
Too much laundry
Overloading the washing machine can prevent proper circulation of water and soap, thus promoting the stagnation of residues and the formation of odors.
Hard or poor quality water
Hard or poor quality water can leave mineral deposits in your washing machine. This can therefore also contribute to unpleasant odors.
Now that we have a better understanding of the origins of these odors, let’s review the tips for effectively eliminating them.
How to eliminate bad odors in the washing machine?
Step 1: a simple wash of the machine drum
Sometimes a simple wash with white vinegar or baking soda may be enough to combat bad odors. This tip (without risk for the joints, we reassure you) will however only be very effective when the problem is in its early stages. This may also not be enough when the problem comes more from the pipes. However, we mention it for those who are not not sure of the origin of the odors.
To do this, pour a large glass of vinegar into the softener container, then empty the rest of the bottle into the drum. Run the hottest program empty. Are the smells still there? In this case, proceed to steps 2 and 3!
Step 2: Clean the machine piping
The machine’s pipes quickly accumulate limescale and various debris. With the residual humidity, mold and bacteria also take advantage of it to invite themselves into the drainage pipe allowing the water to drain. To do this, unplug the device and move it if necessary. Slide a basin or mop under the pipes, at the level of the flexible pipe which exits the machine. It’s the latter that we’re going to scrub! Pour 500 ml of white vinegar into it with a funnel, add 200 g of sodium bicarbonate and let the chemical reaction act for a quarter of an hour. Then pour 3 liters of hot water into it for rinsing. This will melt laundry detergent and soap residue, and other dirt.
Step 3: focus on the machine’s siphon
The siphon can also accumulate dirt and become heavily clogged. Because of this, the smells come back. Provide a basin under the siphon, disassemble it with pliers to loosen the joints and remove the stagnant water inside. Leave to soak in another basin with vinegar water, then use a toothbrush to clean the inside of the siphon. Then rinse it well and carefully put them back in place. No more smells!
How to avoid unpleasant sewer odors in the future?
Regular cleaning with vinegar as well as a more thorough washing of the siphon and pipes will help combat bad odors. However, prevention remains your best anti-headache ally. Here are some tips to prevent the development of foul odors in your washing machine in the future.
Use the right amount of detergent
Avoid overdosing on your detergent or softener. This will not make the laundry or the machine smell better, quite the contrary. So, follow the manufacturer’s recommendations for the appropriate amount, because excess product may leave residue in the machine. Moreover, favor liquid detergents. They tend to leave less residue than powder detergents. This helps prevent odors.
Maintain the washing machine regularly and take care of it
After each use, always leave the washing machine door open for a while. This will allow the drum to dry and reduce the humidity that promotes the growth of odors. If necessary, also pass a wipe at the joint to remove residual water. This will prevent mold from developing. Finally, check the filter regularly from your washing machine and remove debris (elastic bands, tissues, hair, etc.), anti-fade wipes and other particles that may accumulate there. Without obstruction, the washing machine will work optimally and unwanted scents will no longer appear.
Wash at high temperature
Laundry can generally be washed at 30°C very effectively. From time to time, however, carry out a high temperature washing (60°C or more) to eliminate detergent residue, mold and bacteria. Make sure your machine allows it.
Avoid leaving wet laundry in the machine
Do not leave wet or damp clothes or household linens in the machine after the cycle has finished. In fact, this can encourage the formation of odors in the device. In addition, freshly washed clothes may also smell very bad. So get into the good habit of do not leave laundry lying around for too long after washing.
If the problem is very recurring, be aware that there are also anti-odor and anti-backflow valves for all brands (Bosch, Beko, Candy, Samsung, Brandt, Whirlpool, Siemens, etc.) and all models in DIY stores .
