Do-it-yourself repair of activator-type washing machines

In detail: do-it-yourself repair of activator-type washing machines from a real master for the site my.housecope.com.

If you decide to repair the washing machine yourself, first remember if you know the basic techniques for working with mechanisms and electrical circuits. In order for the repair to be carried out correctly and without unpleasant consequences, you should have documentation for the car, a universal set of tools and everything for working with electrical circuits. Remember to work with electrical equipment. Therefore, be sure to unplug the washing machine before starting work. It is also advisable to move it so that during disassembly and assembly you do not have to look for a place to place parts and assemblies, as well as a tool.

As a rule, a malfunction occurs as follows:

Fault analysis makes it possible to correctly diagnose and, using the instructions below, correctly eliminate the problems that have arisen.

In this article, we will look at what to do if the activator is worn out. How to remove it from the washing machine and replace it according to all the rules so that the semi-automatic machine will continue to serve like new.

Activator washing machines are relatively simple, but their parts wear out as often as automatic machines.

An activator is a disc located on the side of the wall or at the bottom of the tub, which rotates during washing and mixes the laundry, "activates" the washing. There are small blades on the outside of this plastic disc.

Activators may vary in size and design, but the task is the same - to move the laundry in the tub.

Modern automatic washing machines also have an activator installed inside the drum. It's called a rib punch and looks like a barrier. His tasks are similar - to break the lumps of linen and shake it so that the quality of the wash is as high as possible.

Another purpose is an additional stiffener.

There are two types of cars: with a vertical and horizontal activator. The activator of the semi-automatic washing machine, which has an additional spinning tank, also has a horizontal arrangement.

When disassembling such machines, there are a lot of technical nuances. Let's consider each case separately.

Among these machines you can find the following brands:

Before removing the activator of the semiautomatic washing machine, disassemble it. To do this, you need to make a key with which you can unscrew the part.

Why do you need a key and why can't you buy it? It's hard to explain, but Soviet manufacturers designed the machine in such a way that each activator needs an individual key. Fortunately, it is not difficult to make it.

Let's consider everything on the example of the common brand "Baby". Take:

  • pipe (15 cm longer than the diameter of the activator body);
  • drill 6 mm;
  • 2 bolts;
  • 2 nuts.

Drill 2 holes in the pipe, 95 mm apart. Insert the bolts there so that another 1-1.5 mm are visible from the other side, secure with nuts.

Now this "key" can be used to remove the activator.

Remove the part in the following sequence:

  • Remove the plug from the side of the machine.
  • Turn the activator by hand so that the holes in the impeller and the housing are aligned.
  • Block the motor rotor with a screwdriver.
  • Insert your hand-made key into the activator body and carefully unscrew the part.

Attention! Where to turn - to the right or to the left - is not known for certain. It all depends on the brand and model of the washer.

After you have removed the old activator, take a new one and assemble the equipment, proceeding in reverse order.

If you removed the activator not to replace a part, but to completely disassemble the body, continue to disassemble. How to disassemble the Malyutka washing machine, we told in previous articles.

The activator rotates due to the belt drive, as in automatic washing machines. Removing the Akivator from them is just as easy:

  • Unplug the washing machine.
  • Loosen the bolts that secure the electric motor.
  • Remove the drive belt from the pulley.
  • Remove the nut that holds the pulley.
  • Knock out the stopper.
  • Remove the activator.

When replacing the activator of the washing machine, do not forget that there should be a distance of no more than 2 mm between it and the tank, and an axial offset of no more than 0.5 mm. Shim the washer to adjust the part.

Their difference is their size and capacity: they can wash up to 2.5 kg of laundry per load. The metal body is painted and has a rectangular shape, and the activator is located on the side. When repairing washing machines of the activator type SM-2, you need to proceed in the following sequence:

  1. Unscrew the back cover and set aside.
  2. Remove the drive belt.
  3. Remove the bolt that secures the pulley.
  4. While holding the activator, remove the pulley.
  5. Remove the required part.
  6. Reassemble the washing machine in reverse order.

All automatic or semi-automatic machines that do not have a drum, we used to call activator. But some Deo models also have a drum.

Consider how to remove the edge of the washing machine drum step by step:

  • There is no need to remove the drum. It is enough just to remove the rim: move the clips aside and remove.
  • Unscrew the nut that holds the activator. The mount is located at the very bottom of the tank, so it will be more convenient to work with a socket wrench.
  • After removing the nut, pry the part with a flat screwdriver and remove with the nut and washer.
  • Buy a new original part. Replace, secure with nut.

Important! Find a partner before repairing your washing machine. It will hold the drum while you unscrew the nut to prevent it from rotating. It is possible to jam the drum with a bar, but this is unsafe for the rotating mechanism.

If you do not know how to replace the rib punch, then do not hesitate - even a beginner can do this task. Just follow our guidelines:

  • Arm yourself with stiff wire or spring.
  • Bend the tip into a hook.
  • Insert the wire into the hole on the fin punch, push it down and pull it towards you - the part should easily detach from the latch.

You don't need a tool to install a new fin punch:

  • Feed the part up a little, and then put the counterpart on the hooks.
  • Next, tighten the hooks with an awl, passing it through the holes.

Any of the listed works can be carried out without the help of a specialist - with your own hands and without a special tool. If in doubt, use the advice from the video:

Many in the country or in the villages still use activator-type washing machines of Soviet-era models (Minivatka, Fairy, Hope, Azovye, Baby, Riga, Alma-Ata etc.). In these machines, the motor is controlled by a cyclic time relay. The most common are relays RVTsM, RVTs-6-50, RVR-6... Over time, these relays wear out the clockwork and the group of contacts. There are cases of arc striking between adjacent contacts. In all cases, further operation of the cyclic relay is impossible.

Of course, when repairing a washing machine, you can bypass all service centers, bazaars and find the same or similar relay and replace it.But you can go the other way, replacing the failed relay with a control unit built on a microcontroller. The use of a microcontroller makes the control unit more flexible. I went this way too. Developed a scheme

wrote a program for the microcontroller with such time cycles as the client wanted. Namely: 20 cycles of 1 minute with pauses between them of 20 seconds.

The circuit is very simple, built on a microcontroller PIC12F675... Almost any transistors with reverse conduction can be used. In my case - KT817G... Relay I applied firms OMRON with powerful contacts.

In washing machines, two types of motors are used, respectively, they have different connection schemes. This unit will work with any engine by connecting the contacts of both relays accordingly. Both options are shown in the diagram. Some washing machines use a simple timer that does not allow the direction of rotation of the motor to be changed. By using this device on such machines, the quality of washing will increase.

In the washing machine being repaired, a cyclic relay of the RVTsM type was installed, it looks like this

I didn't find a single inscription on the engine; three wires come out of it. 10μF 600V capacitor.

I assembled the circuit on a circuit board and placed the entire device on a panel removed from a typewriter
