Bosch wff 1200 DIY repair

Details: bosch wff 1200 DIY repair from a real master for the site my.housecope.com.

Hey, BOSCH specialists!
Washing machine BOSCH WFF-1200
S / n 7603 50091
The washing machine (front, full-size) does not rotate the command device. I checked all the periphery - everything is normal. The commander is hybrid, the stepping mechanical part was checked by plugging the motor into the socket, and the terminals with a multimeter for "ringing" - everything is also normal. There is a suspicion that voltage is not supplied to the processor, but maybe the processor also does not reach the commander's motor and motor control relay.
The problem is that there are a lot of planars on the board, and it is stupid to track where the voltage disappears is impossible.
Who knows on what points (legs) and how much tension should be on the working commander?

The data is as follows:
To / device AKO 513011 306 3737 AA2 076 (hybrid)
Sticker 3995970 В007778АВ5
AKO card 15621 02 S 1
AKO 451279 processor
BSHG_MH1_V1.10
OF80B
HLFQ9603

At the same time: who knows where to get a circuit for such a machine, or even better for a module. It is possible for the money.

If you turn the commander with your hand, he does everything: fills in, drains, heats up. These functions are controlled by the mechanical part of the commander. And the motor (main) and the motor of the controller are controlled by the processor. Accordingly, it does not perform these functions.

There are five zener diodes (or diodes), all planar.
There are three electrolytes. They have some kind of voltage, from 2.7V to 9.8V DC.

The question is, where is the voltage supplied to the processor, and what?

[quote = ”@ lex”] Check the power supply on the processor itself, quartz generation.

There is nothing like quartz there. Please tell me how it looks or is indicated.

Video (click to play).

I'll try the electrolyte today.

Edisson, if you were an electronics specialist, then you would not have created this topic here, since there is nothing complicated there and a circuit is not needed. Although in this case, success is not guaranteed, as the processor could die. But since it's difficult for you and you can't figure it out without a circuit, then you can't figure it out with the circuit either, especially since the commander in the diagram is simply designated as a black box into which the wires enter. Therefore, there is only one solution for you and forget about other options - order a new commander.

Masters, help someone. The Bosch WFF 1200 washing machine does not drain the water. My wife promised to lynch me if I could not cope with the problem on my own. I disassembled the washing machine, cleaned everything of scale, but it still does not drain the water. WHAT TO DO.

Scale does not affect the drain, look into the pump filter.

2Grizel And check the drain hose, if the filter and hose are clean, then look at the pump. Has the machine been working for 5-6 years already?

IMHO, judging by the alphanumeric model number, she is 10 years old, if not more.

Shl. The programmer is probably mechanical. IMHO, it is reasonable to start with it.

what does it mean it does not drain - the pump is spinning? - there seems to be a shield removed from the front and then access to the pump is provided, find a plugged hose - pull out the plug and drain the water into a basin, then unscrew the large plug from the pump and take out the filter.
Does the mop spin in short?

There was a similar problem. The pump was spinning with all this. It was decided by replacing the pump pipes of a suitable size from Ariston for about 700-800 rubles. The pump from Bosch was rejected because of the redneck policy of the Fritzes (the call of the engineer is 2500 rubles + the price of the pump, which will not be sold to you without a call).

I was in the s / c Bosch. Absolutely everything is on sale. What is out of stock - to order.

before buying - you need to decide whether power does not come to it, or the hose or the filter itself is clogged

Maybe the Fritzes have changed their minds. I had this situation 4 years ago. The native pump worked for about 5 years.

The pump is a tricky mechanism. If you are sure that the drain system (in the car and pipes to the riser) is clean, there are no blockages, then change the pump, it's in it.

I also bought parts there in January. And their prices are cheaper than in stores for the same goods (the impeller for the rec. Pump costs 500 rubles, and for spare parts M, PartList from 800 rubles).
Have they stopped selling now?

2VVP I've tried for a long time.
That's just asking, how are you doing now?

VVP wrote:

It turned out yes.
I repaired this pump, fortunately: they are not for sale in our city, you need to go to Ufa.
Initial data: the pump rotates normally without load. Filmed and in place without water. But at some point he noticed that it did not rotate. Spin it up - it rotates. After that, you immediately put it on the drain - it drains, but does not drain in the rinse mode.
First, I cleaned all the hoses.
Then he took apart the pump. He pulled out the rotor towards the impeller. With a screwdriver, the force must probably be 15-20 kilograms. It is pulled out together with the sleeves. I did not remove the impeller from the axle. The impeller rotates 180 degrees, probably this is done to reliably start the engine under load. THIS IS NOT A FAULT! It should be so. Synchronous motors are difficult to start. So they come up with all sorts of tricks to facilitate the launch. I scrolled these 180 grams a dozen times so that the rotation was free. After that, the pump began to work, for 2 weeks already, pah-pah without failures.
Most likely, dirt and scale interfered with turning 180 g. impeller.
So: 1. the impeller should turn freely 180 degrees in the rotor axis.

  1. The rotor, due to the built-in magnet, must have a clearly expressed one (maybe 2) stable position. If you hit the impeller with your finger, after stopping it should vibrate near a stable position (at first I did not have noticeable different resistance around the circumference at all, apparently the axle was heavily clogged)

Washing machines from Bosch, namely the wff 1200/1201 series, are unique not only because they are produced by a company known for its excellent quality. It was these machines that managed to be the sales leaders for many years, despite the fact that many manufacturers tried to launch more versatile units on the market.

But the engineers of the company "Bosch" continue to develop models of this popular direction, and very successfully. An excellent solution during this period was the change in the design of the back cover, the electric motor was improved, thanks to a successful solution, it became more convenient to use the handle to select the washing mode.

But despite the ease of use, fans of the wff 1200 and 1201 series still express dissatisfaction with the fact that the functionality of the machines is a little weak. This is especially true if someone has used machines of a newer generation.

- the washing tub can only hold up to 5 kg of laundry;

- 13 programs have been invested. Today it is considered that this is a small amount;

- there are no various electronic devices inherent in more modern washing machines that facilitate the washing process;

- there is no self-diagnosis process in emergency cases, but the automatic shutdown works clearly if an emergency condition has occurred.

Specific model breakdowns

To the special specifics that are required when conducting repair of bosch washing machines wff 1200 or 1201, applies to work on the electric motor. Replacing the engine brushes does not require such a lengthy procedure as disassembling a complete unit to remove the engine from the tank.

    The Bosch WFF washing machine is a legendary series of automatic machines, many of which have already served their owners for 20 years. Simple and reliable, they still cope with laundry by 5 points. These models can no longer be found in the retail network, but they are still found in the secondary market. The repairmen recommend buying them, since the quality of the machines of the famous Bosch Wff series is the highest.

    Image - Bosch wff 1200 DIY repair

    Exterior view of the Bosch WFF 1201 machine

    On the Russian market, the series is represented by only a few models. 1200, 1201 and 1401 have survived to this day. Their characteristics differ somewhat even within the same model. Now this is impossible. Bosch renews its line of washing machines almost every year. The units do not stay on the market for a long time. The slightest difference, improvement, revision, leads to the emergence of a new model, and not a modification, as it was before. As a result, the user often cannot understand how one model differs from another. Things were different with Bosch Wff. They appeared at a time when manufacturers wrote in the manuals "the characteristics of the model can be changed without warning."

    Models WFF 1200 and 1201 were produced in 1997-2002. They turned out to be the brand's latest electromechanical control units. During all 5 years of production, the developers have been improving. Changes were made to the design of the motor, control panel, etc. One of the goals was to hang maintainability. And it succeeded. The maintenance of the series machines is inexpensive for users. And even now, after 15-20 years from the date of release, WFF machines are being successfully repaired, if required.

  • For medium soiled white cotton. Temperature - 90 °. Loading - maximum.
  • For colored cottons and other fabrics. The admissible temperature is 30-60 °. In this mode, you can also load a full tank.
  • A quick program for lightly soiled items. True, by modern standards, the cycle is quite long. Therefore, it would be correct to say that the machine does not have a short program. But there is a mode that lasts more than an hour for things that do not require thorough cleaning. Suitable for synthetic fabrics, as the water heating temperature does not exceed 30-40 °.
  • Finish.
  • For non-capricious, not too dirty laundry. Temperature - 0-60 °.
  • Economical washing of non-capricious linen at temperatures up to 40 °. In this mode, energy consumption is reduced due to weaker water heating and a shorter program duration. You can clean up to 2 kg in this mode.
  • Shortened program for lightly soiled, non-whipping laundry at temperatures up to 30 °.

  • For delicate laundry.
  • For woolen products.
  • For delicate woollens requiring special handling. Cleaning is done in cold water. As a result, powder detergent cannot be used. However, it is undesirable to wash woolen things in it in any case.
  • Reduced program for cleaning wool items.
  • Pumping out water. The mode is designed to remove water from the tank after stopping washing.
  • This model does not have a very short program that allows you to wash sports T-shirts or refresh only purchased items. The shortest mode lasts a little over an hour.

    Despite the unanimous positive opinion of users about the machines of the series, they still have drawbacks. Especially when compared with modern assistants.

    Having served for two decades, the WFF 1200 continues to delight the owners. There are not many reviews on the network, since at the time of the appearance of the series machines, most users did not have access to the Internet, but they are all with a plus sign. Someone's car continues to serve without a single breakdown. Someone managed to carry out inexpensive maintenance by replacing small parts. There are no complaints about the inability to repair the car.

    The WFF 1200, like any modern machine, collects water in the rubber boot of the sunroof. It must be removed manually

    Repairers also speak positively of these machines. It is their quality that is usually cited as an example when they say that the old German assembly is much better than today's Russian one. This is partly true. The machines of those years really have a great resource. But their capabilities are still lower than those of modern assistants. They do not have complex electronics, which are very expensive to repair. They have a lot less plastic elements. Manufacturers put a greater resource in them, since in those days the technique did not become obsolete so quickly.

    The WFF series machines not only break down less often. The same units are easy to repair. For example, many modern Bosch models have a non-separable drum. As a result, bearing failure costs the user half the cost of the entire machine. Repairing WFF is relatively simple and not burdensome for a wallet.

    Specifications Bosch WFF 1400

    Modern models are produced taking into account the rapid obsolescence. It makes no sense to put a huge resource into the equipment, if after 5-7, maximum 10 years, it ceases to meet modern requirements, for example, in terms of energy consumption.

    You can't call it very quiet. The Bosch WFF washing machine runs relatively loudly during spinning. Not so much as to spoil the relationship between the owners of the machine and their neighbors, but still in this indicator it is inferior to the later models of Bosch.

    As mentioned above, the Bosch WFF washing machine has a control panel in German. Therefore, despite the many advantages and low price of these second-hand machines, it is still not worth buying it for her grandmother at the dacha. Even with instructions, an elderly person, whose memory leaves much to be desired, will constantly get confused in buttons and programs.

    Bosch WFF in the interior

    The Bosch WFF series machine washes well. This is not surprising, given that the minimum wash cycle lasts more than an hour. And the bulk of user complaints about the quality of washing is caused by the use of accelerated modes with a large load of dirty things. Those. when used for other purposes. However, the machines of not every brand can cope with washing dirty clothes, even with prolonged washing. Bosch is at its best here.

    As you can see, the Bosch WFF washing machine in most parameters is not inferior to inexpensive modern models. And even has an advantage over many. Of course, over 20 years of service, the plastic part of the machines turned yellow, and the cars no longer look smart. But for work they are still relevant.

    The washing machine itself is a complex mechanical device with an equally complex electronic control unit.Household appliances from Bosch are known for their reliability and quality, but, like any device, they can also fail. This may be due to both violation of the operating rules and in connection with the natural degradation of parts and elements of the machine.

    In order to be able to perform professional repair of washing machines with your own hands, you must not only understand the principle of operation of the device, but also have a variety of tools, have knowledge in electronics, and be able to read electrical circuits. But everyone can carry out simple repairs. The main thing is to accurately determine the faulty unit, the self-diagnosis function built into the washing machine helps in this.

    Regardless of the brand of the washing machine, the device of models from different manufacturers, be it Atlant or Bosch, practically does not differ. The main nodes include:

    • drum;
    • pump;
    • Control block;
    • heating element (heating element);
    • engine.

    After turning on the machine and selecting a program, the pump starts pumping water into the drum through the inlet valve. The drum is a container made of stainless material with many holes along the entire surface. It is through these holes that water penetrates into the container, reaching the desired level. The water level is monitored by a pressure switch. The drum is connected via a belt drive or directly connected to the engine. According to the selected program, the engine starts its work, forcing the drum to rotate. At the front, the drum is connected to the tank via a rubber cuff.

    At the end of the wash cycle, the water is drained out. The main unit of the drainage system is the drain pump. A special hose is connected to the pump outlet, through which water is drained from the device. The last stage of the machine is spinning. For its implementation, the engine begins to spin the drum at high speed. Under the action of centrifugal force, things inside are pressed against the surface of the drum. Water is squeezed out of the items and exits through the holes in the drum. The squeezed out water accumulates at the bottom of the tank, from where it is pumped out by a pump. The operation of the pump and the motor is controlled by an electronic unit.

    The water in the device is heated using a thermoelectric element. It has the form of a bent tube, inside which there is a conductive thread in the middle of the insulator layer.

    In addition to the main components, sensors are important elements in washing units. They allow electronics to control the processes taking place during the wash. The following sensors are used in cars:

    1. Image - Bosch wff 1200 DIY repairPressostat. It can be performed both of a mechanical type and an electronic one. Its task is to control the water level.
    2. Thermostat. Located at the bottom of the tank and is designed to monitor the temperature of the water.
    3. Tachometer. Measures engine speed.
    4. Sunroof locking device. It is an electromechanical device. It informs about the opening of the hatch and blocks it when starting the wash.
