What to do with the rest of the machine parts?

In fact, you won’t get much from selling a washing machine for metal, but selling off the main parts, if they are still working at full speed, may well bring in a good income. Among craftsmen specializing in SM, elements such as a control module, motor, and drain pump are in great demand, so they can be removed, independently, and sold together or separately.

In addition, if you do not have time to disassemble the washing machine, sort the elements and search for copper, you can contact companies that not only buy the entire units, but also remove them themselves. For such a procedure you can earn from 500 rubles with an obvious number of advantages.

1. This is obviously more profitable than selling copper from the motor for scrap metal.
2. Other people do the main work for you, which saves effort and time.
3. If you live on a high floor, representatives of the reseller company will also lower the unit, and given the weight of the washing machine, this is another advantage.

Obviously, searching for metal in the elements of the washing machine, then selling it for scrap and recycling what is left of the washer is a less profitable and more energy-consuming procedure than simply selling the unit’s parts.

Various options

There are several ways to get rid of your old machine:

• Dispose of as household appliances. It must be said right away that this option will cost you 1500-2000 rubles. The fact is that household appliances are disposed of in special landfills, after being shredded. The funds will be used to pay for transportation and the processing service itself.
• Place advertisements in a newspaper or on the Internet. There are a large number of people who want to take away their old washing machine. You can consider selling it (if the machine is in good condition) or giving it away for free.
• Return it to the store. Of course, we are not talking about returning it. Many household appliance stores hold promotions in the “Change new for old” format.
• Donate a car to an orphanage. If your washing machine is still operational, you can donate it to an orphanage. As a rule, such institutions always need help.
• Sell ​​your washing machine for scrap.

Sell ​​your washing machine for scrap

Washing machine for scrap metal. Unfortunately, nothing in our world lasts forever. This also applies to household appliances, and in particular washing machines. Statistics show that the average lifespan of a washing machine is 5–8 years, taking into account intensive everyday use. Often repairs will be quite expensive, and no repairman will give you a guarantee. It’s easier to buy a new car, and an old one... But where to put the old washing machine? More details below.

Summing up

In conclusion, I would like to say that the future fate of the machine, after purchasing a new one, is chosen by each owner independently. Depending on its condition, it can either be sold, donated, or sold for scrap. Of course, you can leave the old washing machine at home as a cabinet, but this option will suit few people.

When the machine works from repair to repair or fails completely, the user has no choice but to buy a new unit. But what to do with the old one? The easiest way is to simply throw it away, but some enterprising citizens are thinking about a different perspective. Is it possible, for example, to sell a washing machine for scrap and get some money?

Disassemble an electric motor for repairs

They covered aspects characteristic of a poor country: how to disassemble an electric motor for scrap. Let's add here: the magnetic circuit is formed by plates of good electrical steel, which can be used in the manufacture of transformers. Let's see how to repair an electric motor. We will describe the components, since burnt out windings are not always the cause of product failure.

Let's say one stator winding of an electric motor breaks down. Wind up: the wire is laid out in a magazine, the footage is small. Better than paying a couple thousand to buy a new electric food processor motor. It's funny, they sell wire... by the cubic meter, by the kilogram. Traders, roughly speaking, fill people's heads with unnecessary worries. How to measure the winding of an electric motor in cubic meters? Draw your own conclusions: sometimes you look at the dealer, his tongue is full of obscenities. Those who write are more pleased: the price for the wire of the electric motor windings must be requested.

The coil cannot be expensive: for 1 kg of copper they ask for 550 rubles. Enough to wind the stator (both poles) on half a dozen food processor motors. Consequently, the economic effect is obvious; you need to disassemble the electric motor winding to measure the parameters. Let's get started.

• You'll quickly notice that although most electric motors require 230 volts to operate, there are actually many more leads than required.

Typically, thermal relays and thermal fuses are placed in the winding. Protects against overheating. We have already written: each varnish insulation has a limit, so thermal fuses are manufactured in accordance with the requirements. Typical values ​​are 135 – 145 degrees Celsius. On the asynchronous motor we see two black wires: between the turns and the magnetic circuit there is a protective element designed to withstand a temperature of 145 degrees.

In this case the contact is quite poor. There are models of electric motors where the thermal relay is tightly screwed to the plates, or wrapped in insulation between the turns of the windings. Start checking with the protective elements. Sometimes the power connector's own terminals lead there; often the thermal fuse is simply connected in series with the winding. When triggered, the tester will record a gap. Please note: it is not always possible to measure resistance through the terminals. It is much better to ring the engines with an active indicator screwdriver.

• Many household engines are equipped with sensors for measuring shaft rotation speed. They use the Hall effect, there are other varieties. Once you decide to repair the engine, you most likely are not interested in speed meters.
• If you decide to disassemble the electric motor of a vacuum cleaner, you will immediately notice: near the collector, “drops” (round in shape) are connected to the housing.

No breakage even if blackened by high temperature. Drop-shaped varistors help protect the brushes against power surges. With a sharp increase in potential, the resistance of the elements drops, the spark is extinguished by the thickness of the steel body of the engine. The motor on the left (see photo) is equipped with varistors (there are thermal relays containing a button-type sensor from Klixon 3MP series). Varistors are difficult to test; they can cause breakdowns only in one case - during a short circuit. Let's check with a tester whether this is the case. In a quiet state, without power, the resistance of the varistor is high (often more than 20 MOhm).

• Brushes are considered the weak point of commutator electric motors.

Wear leads to a circular fire. It is much easier to disassemble an asynchronous electric motor with a squirrel-cage rotor. The brushes rest on the lamella with springs. When you try to pull the engine manifold out, they will jump out in the direction of the shaft. In power tools, the holders are secured with bolts and covered with covers; it is relatively easy to remove the graphite. When it comes to food processors, servicing of products outside of workshops is not provided by the manufacturer. The holder is held in place by curved brass tendrils. Obviously, we avoid trying too hard to practice flexion-extension, otherwise it is easy to break off the fastening elements. It is better to remove the brushes before removing the shaft. It will facilitate the subsequent assembly process and protect the graphite from destruction.

Basic ways to get rid of old equipment

In general, there are many more ways to get rid of an unnecessary washing machine than it seems. All of them are different in terms of financial costs/profits, and in the amount of time and effort. Here is a list of the main options:

1. Recycle. The bottom line is that you personally take your unit to a specially designated place, where you also pay 1500 - 2000 for the procedure. This money goes towards transporting the machine to a special landfill and the recycling service itself.
2. Sell ​​or give away for free. Of course, this can only be done if the device is still in good condition. Some people will be happy to come and remove the car themselves if you offer it for free.
3. Give it to the store. This refers to various promotions like “Changing the old for the new.” You can save some money and get rid of the equipment.
4. Donate to an institution. Orphanages and any other similar institutions gladly accept any help. Household appliances are never superfluous, so why not do a good deed if your machine is still in good working order?

Well, if the home helper has already outlived its usefulness, of course, the most profitable thing to do is to sell it for scrap metal; as you can see, the content of valuable metals is quite high. Even if it’s not very convenient to transport, it’s still better than paying extra for disposal.

Selling a washing machine for scrap - how much will we get?

According to statistics, the average service life of a modern washing machine is limited to a period of 5 to 8 years. When purchasing a new unit of household appliances, the relevant question is where to put the old unit. Depending on the condition of the old washing machine, there are several options for solving the problem.

• It is easy to sell serviceable but obsolete equipment through free classifieds sites on the Internet with the obligatory condition of self-pickup.
• You can give away a faulty washing machine for free by posting a corresponding advertisement on the Internet.
• Use the services of a company for recycling large household appliances. Typically this service is provided for a fee. A fee will be charged for transportation and subsequent disposal of the unit.
• Take it to a large hardware store as part of a special promotion aimed at recycling old appliances. In this case, the responsibility for delivering a unit of household appliances to the sales floor falls on the owner of the washing machine.
