Why does a new washing machine smell like plastic?

Has your new washing machine ever given off an odd plastic odor? Many people who have recently purchased one have this common concern. Not only is this smell bothersome, but if you don’t know what’s causing it, it could be a little concerning. Gaining an understanding of the reasons behind this can help you relax and make the most of your new appliance.

The materials utilized in the manufacture of new washing machines frequently give them an unpleasant plastic or chemical smell. The plastic components and protective coatings that haven’t had time to completely air out are what are causing this odor. Usually, the smell goes away on its own as these materials are exposed to air and heat over time.

Remaining residue from the production process could be another cause of the odor. Machines are occasionally packed with these residues to guarantee optimal delivery conditions. To ensure your machine is ready for laundry, run a few cycles with just water or a mild detergent to get rid of any residual odors.

Source of the stench

When turned on, almost all new equipment emits a distinct plastic odor, and washing machines are no different. This is typically regarded as the standard. The rotation mechanisms, particularly the rubber parts, are worn out in the early days of operation. There’s a faint humming sound along with the grinding, and an odd smell. The components "get used to it" over time, and the offensive vapor release ceases.

Make sure the washing machine is the source of the smell and not the outlet, power cord, or extension cord!

The most important thing is to get rid of the burning smell right away. In certain cases, a heating extension cord, outlet, or damaged insulation can be the source of the disagreeable "odor." You have to de-energize the equipment and inspect the electrical network in this situation; you cannot delay. Not everything that is "smelly" comes from wiring and grinding in mechanisms. The machine’s drive belt, tank, cuff, engine, cheap parts, and powder can also cause it to release plastic fumes.

• Tank and cuff. During the first washes, plastic polymer tanks heat up, releasing plasticizers and chemical additives – this is inevitable.
• Drive belt. A slipped or poorly stretched rubber band on the drive heats up when the pulleys rotate and emits a characteristic odor. Here you should intervene: replace or fix the "rim" correctly.
• Poor-quality components. Cheap plastic emits vapors when heated, and the worse the build quality, the longer the "stench" will last.
• Washing powder. Poor-quality detergent is an unobvious factor why the washing machine smells. Try changing the cleaner first.
• Engine. We are talking about un-lapped electric brushes, the carbon tips of which are initially worn against the motor body. Or about a leaking tank.

Investigating the cause of the washing machine’s plastic or burning odor is preferable. At the very least, rule out any risky possibilities like overheating wiring, leaks, and drive belts. The action plan, step-by-step, will be explained below.

How to solve the problem?

It is not advised to disassemble the washing machine right away if there is a smell similar to "plastic." First of all, it’s best to wait since there probably isn’t anything to worry about. With time, all volatile materials will evaporate, and the odor will vanish as well. Second, you might forfeit the warranty if you open the case yourself.

It’s best to hold off. The most important step is to make sure that the machine’s electrical network is free of issues. No one will pinpoint the precise duration when the odor should go away on its own because it all depends on the manufacturer and the caliber of the assembly. Usually, after five to fourteen days, things settle down.

Cleaning the washing machine with specialist chemicals is advised if the laundry that was washed in it smells in addition to the machine itself. One "wash" of the machine with vinegar, citric acid, or a specialized cleaner should be sufficient. It’s critical to adhere to the dosage recommended in the instructions. If cleaning and waiting don’t work, you should carefully inspect the machine using the procedures listed below:

• carefully remove the top and side covers of the case;
• turn on the washing machine at full power and wait until the smell intensifies;
• turn off the machine and feel the drive belt, cuff, wiring (is there excessive heating).

The identified malfunction will determine the next steps to take. Usually, diagnosing the engine and drive solves the problem. Below are detailed instructions.

The culprit is the engine

The engine of the machine occasionally gives off a burnt plastic smell. Water that got on the engine can occasionally be the cause of the issue, but more frequently, worn-out or improperly rubbed-in brushes are the issue. In the first scenario, replace the "coals" with fresh ones if the second scenario requires you to wait. Most people are able to complete the task. What must be done in order to swap out these components:

• disconnect the machine from communications;
• move the rear panel of the case aside;
• pull the drive belt off the pulley;
• find the motor under the tank;
• release the motor from the wiring;
• loosen the bolts holding the motor;
• remove the engine from the machine;
• find the electric brush on the housing;
• unscrew the bolts holding the brushes;
• remove the "carbons";
• install new brushes.

A crucial point to note is that new brushes are always replaced in pairs. The washing machine’s serial number determines which analogs are chosen. The old rods should ideally be taken out and brought to the store. Use a multimeter to quickly check and ring the motor winding. It might be broken, short circuit, overheat, or have a burnt-like smell. You should inspect the tank if the engine is operating properly. Water can seep through even the smallest crack, and when it gets on the motor, it causes an "amber."

Because of the residual chemicals used in manufacturing as well as the plastic components themselves, new washing machines frequently smell like plastic. Usually harmless, these smells should go away after a few washes. Knowing this can allay worries and guarantee that you’re not worrying about something that will work itself out.

Drive belt

The drive belt is the source of the burnt plastic odor coming from the back of the machine. The pulley starts to rotate along a different trajectory and the rubber rubs against adjacent components due to worn bearings and improper installation. The smell is particularly strong during the spin cycle. Black smoke occasionally emerges from the washing machine. It is simple to replace the drive belt:

• disconnect the machine from communications;
• remove the "back" of the case;
• drop the rubber from the pulleys;
• pull the new belt first onto the engine pulley, then onto the drum.

Determining the cause of the belt’s "skewedness" is preferable. You will need to replace the seal as well as the bearings if the problem is with the bearings. This is accomplished by disassembling the machine, removing the drum from the housing, knocking out the old rings, and then installing new ones.

Don’t freak out if your brand-new washing machine smells like plastic. With many modern appliances, this is a typical problem. The machine’s plastic parts, such as the hoses and drum, are typically the source of the smell. These parts can release odors when they heat up during the machine’s initial uses. As you continue to use the machine, this should go away because it is perfectly normal.

Try using just water and a cup of white vinegar in a hot water cycle to expedite the process. This aids in the smells’ breakdown and dissipation. To completely get rid of the smell, you might need to repeat this a few times.

Recall that the main objective is to allow your machine to become used to your home and its new surroundings. The machine should eventually lose its plastic smell as it is used. It could be worthwhile to get in touch with the manufacturer or an expert for advice if the smell lasts for an exceptionally long period.
