In detail: do-it-yourself repair of the thomas twin t1 vacuum cleaner engine from a real master for the site my.housecope.com.
After five years of operation, the vacuum cleaner began to howl harshly during operation. The sound is clear, the bush hummed. Waiting for it to crumble and smoke was somehow not a hunt. I decided to take a closer look at the patient. The price of the new engine on the servicemen's website was not pleasing, almost a third of the cost of the vacuum cleaner. Doesn't seduce against penny bearings.
A study of the resources showed that there are disassembly instructions, but only text. Filmed the disassembly process itself. No particularly difficult moments have been identified.
So let's get started. We unscrew the two screws and remove the top cover, so that it does not interfere
Next, turn the vacuum cleaner over and unscrew the 6 screws on the bottom cover. Two of them are located under the air intake filter cover.
We turn over and halve the case, there are no latches and latches there, you just need to shake it and it will turn out
We unscrew 4 large screws and one small one on the cover that covers the engine. We take out the wires from the mounts and slide the cover along the wires
The engine is simply removed from the housing.
Next, we follow the instructions found on the Internet.
Disassembled according to this instruction for Thomas Twin TT with my comments
1. Remove the motor from the black casing - flow divider by unscrewing 4 screws and removing the power terminals from the motor (write down where they were). The terminals are pulled together by light rocking.
2. Turn the engine upside down (galvanized part down).
3. Carefully pull off (as if contouring) the black plastic casing-pipe, pulling, one by one, the latches. You need to shoot carefully, I broke a nail, for example. I overdid it a bit.

4. Remove the clamps from the brushes by bending the clips on the terminals with a screwdriver.
5. Remove the brushes by bending the bronze clips to the brush body. My brushes were just pressed with springs. I squeezed them out with my finger and just pulled the brushes out of the top cover.
6. Put a socket wrench on the nut, from the side of the turbine, unscrew the fan impeller by hand, throwing a rag over it, if there is no special wrench. Left-hand thread, i.e. unscrew clockwise. There is an aluminum washer under the impeller, do not lose. I didn't have the puck, so I couldn't lose it. The impeller took off without problems
7. Remove the white plastic bearing holder (although the brushes too) by unscrewing the 2 screws in the grooves. There is a spring washer on the bearing, remember its position. The lid was not on screws but on a nut, although it was not important. The position of the spring washer is easily identified by the grooves in the rubber bearing cap. In my opinion, it is better to install the washer back with support on the unworked places.
and here is the washer and nuts
8. Remove the stator.
9. Unscrew the aluminum nut from the turbine side (right-hand thread). Try to do this by holding the rotor in your hand. In my case, I had to grip the rotor in a vice, since the thread was rusted. Plugging the thread for 2 days with a mixture of oil and kerosene did not help.
10. Place the product in its original position. There is a retainer under the rotor, above the bearing, we remove it gradually, moving each petal upward a little, in a circle, until the retainer washer comes out completely. Remove the rotor. Remember the location of the parts in the bearing assembly.
11. Disassemble the turbine, if required. - Bend the latches around the circumference. Next, you need 4 hands. With both hands, hold the turbine in suspension by the plastic part, and with it to the top, gradually knock down the galvanized cup in a circle with an aluminum pin, lightly hitting it with a hammer.
Interestingly, the top bearing turned out to be 607-z, although all sources write that 608-z.

The power button also stopped working, alcohol helped, but not for long, for about a month, bought a button that was on the board for $ 1, and asked a friend to replace it, we have a button size of 12x12x7 (height), but I bought 12x12x5, I had to lengthen it above.
I disassembled the old button, and in principle there is nothing difficult there, you could just disassemble it and clean up the contacts.

What to do if your thomas tt vacuum cleaner stops turning on? In this article, I will tell you how to repair your Thomas vacuum cleaner yourself, namely, repair the power button at home.
For a Thomas TT vacuum cleaner of this model, the main reason why it does not start is the power button, which is located on the control board. Such a repair is not particularly difficult, and then I will tell and show you how to make this repair with your own hands.
For repairs you will need: a Phillips screwdriver, a soldering iron and consumables for soldering.
We turn on the soldering iron in the network while it heats up, take a Phillips screwdriver, unscrew 6 screws that are located at the bottom of the thomas vacuum cleaner, 2 of them are under the filter cover.
Next, we need to remove the top of the Thomas Twin tt case.
The control board with which we will carry out repair work is circled in red. The board is attached with 2 screws that we need to unscrew.
Important! There are 3 wires connected to the control board. When you disconnect them from the board, remember how they were connected, or better with a marker, sign where which wire was connected, because if you connect it incorrectly, when you turn it on, the semiconductor will immediately burn out, which regulates the power of the thomas vacuum cleaner. Take a Phillips screwdriver, unscrew the bolts and remove the control board.
The Thomas vacuum cleaner start button is soldered on the back of the control board, we need to replace it with a new working one.
You can buy a similar button in any radio store, as it will not be difficult for you to find it. We take a preheated soldering iron and solder the old button in order to replace it with a new working one.
After we have replaced the button on the control board, it can be replaced. We connect the wires to it and assemble the Thomas Twin tt vacuum cleaner back.
We connect all the terminals, assembled the vacuum cleaner and turn it on. Our twin tt vacuum cleaner started up the first time, which means that this repair of the thomas twin tt vacuum cleaner was successful, and again you can continue to use your house assistant. As you can see from this material, repairing a Thomas vacuum cleaner with your own hands, namely, repairing the power button, is not difficult, and you can make repairs yourself at home.

Three years ago I bought a Thomas Twin T2 Aquafilter vacuum cleaner. Today the pump stopped working, disassembled, looked, assembled - it does not work. Unfortunately, there were no clamps. to remove it and check it separately. But one of these days I will buy and check.
There are such a small number of pictures. To remember what is happening.
In espresso makers, similar pumps are installed, except that there may be more power. But to find a killed coffee maker, I think, is not a problem.
Yes, they are many where similar, but there was a question with an outlet thread, and I could not find an answer to it. It took a month to find when it was necessary. As a result, bought from Thomas, the price is fun. And I'll play with the old one. And there will probably be a video of how to fix it. For for.

It turned out to be a "combined injury" - a typical death of a button plus a breakdown of the PLC power supply zener diode.
1. See photo:
Here, the broken Zener diode was replaced with the Soviet KS456A (5.6 V, 36 mA, 1 W). Shame, of course, but it works.
The "native" zener diode was "glass":
BZV55 series, model B5V6, parameters 5.6V, 250mA, 0.4W. The specification is here.
Soldered with a cathode (black stripe) towards the 10 kOhm SMD resistor (in the photo there is a black rectangle marked “103”)
UPD.
The zener diode has already changed to a more suitable size - "glass" 1N4734A (5.6 V, 45 mA, 1 W): 
2. The SM4005 diode under the button is a conventional rectifier 1 A 600 V.
3.The triac of the BTA212-600B regulator (12 A 600 V in the TO-220 package), can be replaced with any similar isolated or non-isolated, for example, BTA (-B) 12 (-16, -24) -600 (-800); I checked with the first one that came across - BTB24-600.
To replace, you need to drill the heat sink in the hole of the triac, and fasten the new one with a screw and nut (and thermal paste, of course).
4. PLC 12C508A is not subject to simple replacement (it is programmed to control the motor power).
5. The entire control board has No. 190731, but now it is sold similar (?) With No. 190770 - the price for 09.02.16 is 3021 rubles.
6. The quality of the PCB is rather mediocre, and even when using a soldering station, the foil peels off easily.

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?
First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.
The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hairdryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.
Let's consider the situation if you are a beginner / advanced radio amateur who solders all sorts of electronic gizmos and has some of the necessary tools. You create an appropriate thread on the repair forum with a short description of “patient symptoms”, ie. for example “Samsung LE40R81B TV does not turn on”. So what? Yes, there can be a lot of reasons for not switching on - from malfunctions in the power system, problems with the processor or flashing firmware in the EEPROM memory.
More advanced users can find the blackened element on the board and attach a photo to the post. However, keep in mind that you replace this radio element with the same one - it is not a fact that your equipment will work. As a rule, something caused the combustion of this element and it could “pull” a couple of other elements along with it, not to mention the fact that it is quite difficult for a non-professional to find a burned-out m / s. Plus, in modern equipment, SMD radio elements are almost universally used, soldering which with an ESPN-40 soldering iron or a Chinese 60-Watt soldering iron you risk overheating the board, peeling tracks, etc. The subsequent restoration of which will be very, very problematic.
The purpose of this post is not any PR of repair shops, but I want to convey to you that sometimes self-repair can be more expensive than taking it to a professional workshop. Although, of course, this is your money and what is better or more risky is up to you.
If you nevertheless decide that you are able to independently repair the radio equipment, then when creating a post, be sure to indicate the full name of the device, modification, year of manufacture, country of origin and other detailed information. If there is a diagram, then attach it to the post or give a link to the source. Write down how long the symptoms have been manifesting, whether there were surges in the supply voltage network, whether there was a repair before that, what was done, what was checked, voltage measurements, oscillograms, etc. From a photo of a motherboard, as a rule, there is little sense, from a photo of a motherboard taken on a mobile phone there is no sense at all. Telepaths live in other forums.
Before creating a post, be sure to use the search on the forum and on the Internet. Read the relevant topics in the subsections, perhaps your problem is typical and has already been discussed. Be sure to read the article Repair strategy
The format of your post should be as follows:
Topics with the title “Help fix the Sony TV” with the content “broken” and a couple of blurred photos of the unscrewed back cover, taken with the 7th iPhone, at night, with a resolution of 8000x6000 pixels are immediately deleted. The more information about the breakdown you put in a post, the more chances you will get a competent answer.Understand that the forum is a system of gratuitous mutual assistance in solving problems and if you are dismissive of writing your post and do not follow the above tips, then the answers to it will be appropriate, if anyone wants to answer at all. Also note that no one should answer instantly or within a day, say, no need to write after 2 hours “That no one can help”, etc. In this case, the topic will be deleted immediately.
You should make every effort to find a breakdown on your own before you get stuck and decide to go to the forum. If you outline the whole process of finding a breakdown in your topic, then the chance of getting help from a highly qualified specialist will be very great.
If you decide to take your broken equipment to the nearest workshop, but do not know where, then perhaps our online cartographic service will help you: workshops on the map (on the left, press all buttons except “Workshops”). You can leave and view user reviews for workshops.
For repairmen and workshops: you can add your services to the map. Find your object on the map from the satellite and click on it with the left mouse button. In the field “Object type:” do not forget to change to “Equipment repair”. Adding is absolutely free! All objects are checked and moderated. A discussion of the service is here.
In order to correctly select the model of a washing vacuum cleaner that is most suitable for cleaning your home, you need to have information about the technical characteristics, advantages, disadvantages and important parameters of this household appliance.
Among the disadvantages, it is necessary to mention the impossibility of removing dirt and dust from the surface of carpets and parquets, which have a natural base. This is due to the fact that as a result of wet cleaning, the base of such carpets is not able to dry out, that is, your carpet will start to deteriorate in a couple of days. And this process will be accompanied by not the most pleasant aromas.
However, there is one trick here. If after the wet cleaning you find the opportunity to take the carpet out into fresh air so that it is thoroughly dry and ventilated there, then the quality of the washing vacuum cleaner will cause you some positive emotions.
The situation with cleaning parquet is similar to the one described above. Water here will penetrate between the planks, falling into their base. As a result, the parquet will begin to rot from the inside after a while. But even here there is a way out: the parquet just needs to be made moisture resistant. To do this, it is treated with special antiseptics. Another disadvantage of these household units is the need to wash the tanks of the vacuum cleaner after each cleaning.
All other types of surfaces can be cleaned with it without any worries. Thus, washing vacuum cleaners perfectly remove dirt and dust from:
carpets (don't forget to dry them later),
floors and walls covered with tiles or natural stone.
Also, the advantages include the ability to carry out "dry" cleaning, remove spilled liquids, humidify, deodorize the cleaned rooms, wash mirrors and glasses. The last function requires special equipment - more about them below.
It's simple enough. The first tank must be filled with water and detergent. When the device is activated, the cleaning solution will flow under pressure into the nozzle, from which it will begin to be evenly distributed over all surfaces to be treated. The nozzle is also equipped with special holes designed to suck in already contaminated water entering the second tank. During the cleaning process, you yourself can adjust the amount of water that will be supplied to the carpet.
Recommendation. The wet cleaning process for carpets and carpets should be carried out at maximum power.Otherwise, the surfaces will not have time to get thoroughly wet, which will cause problems with their further drying. Therefore, when purchasing a washing unit, it is better to select the model that is equipped with vacuum attachments with automatic control of the supply of washing solution, and the brush intensively and thoroughly washes every lint of the carpet.
This parameter is fundamental for high-quality cleaning. The more power, the better. However, there is an important nuance here. For vacuum cleaners, it is not the power consumption that is important, but the suction power. The numbers of the first power can reach 1400W-1600W, but the numbers of the second rarely reach 800W-1000W (and only in professional models).
To make more or less high-quality cleaning in everyday life, the suction power should be about 400W. In addition, keep in mind that the power will be spent on the filtration, deodorization, humidification system and on the special equipment of the device.
There is also such a marketing technique: the manufacturer does not indicate the level of the rated power consumption, but the level of the maximum. And it is about 15% -25% higher. However, the device develops maximum power only in the first seconds of operation. For the rest of the operating time, it operates in the nominal mode. So, to calculate the value of the rated power, the maximum value should be divided by 1.4 (square root of two).
Before purchasing a washing unit, you need to roughly imagine how much work it will need to perform. The larger the area of the premises, the more water will be required to clean them.
Any model of a washing vacuum cleaner is equipped with two reservoirs. One is filled with clean water. It is the size of this tank that is important in the final selection of the product. Experience shows that cleaning an apartment of three rooms will require 4-5 liters of clean water.
The models of units offered today can have the volume of the first tank from 2L to 10L. If your apartment has no more than two rooms, then a 3L-4L tank for clean water will be enough. If your house is quite large, then the volume of the tank should be at least 8L-10L. Otherwise, you will have to stop the cleaning process in order to replenish the supply of clean water.
The volume of the contaminated water tank can be from 5L to 20L. You shouldn't think too much about its dimensions, tk. it will depend on the volume of the first tank you choose.
The maintenance process of washing units mainly depends on the location of the clean water and dirty water tanks in them. Because they need to be washed after each cleaning.
The procedure for removing water from containers can take from 10 minutes. up to 20 min. (depends on the model of the device):
In some MPs, the containers are located one under the other (on top of the container for clean water). The downside here is that you can drain the water from the second container only after removing the first container.
The next option is when both containers are designed as one container, i.e. two cylinders (smaller and larger) are inserted into one another. The advantage here is as follows: The first container can be filled with clean water several times before pouring water from the second container.
Today, the most popular option is the use of an additional removable cassette container in addition to a container for clean water in washing units. It is located outside the enclosure. This extra container can be removed in a few minutes. This makes it much more convenient for you to replenish your fluid supplies without having to carry the entire unit to the tap.
Recommendation. When choosing a washing unit, check whether the structure is equipped with special indicators that will prompt you when the containers are empty.
When choosing, it is necessary to evaluate the number and types of filters used in the vacuum cleaner.Since the unit "blows" air into the room during operation, it is very important that this air does not contain the smallest dirt particles.
Modern models are equipped with aqua filters. In this case, the design of the unit contains another water tank. In the course of cleaning, dust and dirt pass through this water and remain in it. The purified air goes out.
Unfortunately, the aquafilter fails to completely filter out microparticles (about 1.5% -2% is missed).
In this regard, fine filters are additionally used in washing units, usually these are carbon elements:
class HEPA (High Efficiency Particutate Air),
These filters are not the same in terms of particle retention efficiency. Filter elements of class S provide 99.97% efficiency (i.e., they retain particles of more than 0.3 µm according to DIN 24184). But HEPA provides 99.95 percent efficiency (i.e., they trap particles more than 0.6 microns according to the EN 1822 standard). In the presence of the HEPA H13 filter, the efficiency level will not be less than 99.95 percent. The rest of the HEPA H10-12 are less effective.
The service life of filters, provided that it will be washed with water, ranges from twelve months to several years.
Some MT makers have gone even further. In order to capture small dust particles, they equip their models with a special separator. The principle of operation is as follows. The smallest dust and allergenic particles, passing through the water, fall into air bubbles. These dirt-filled bubbles rise to the top, which produces one and a half to two percent of uncleaned air. Then the separator creates a kind of fog from the water droplets at a high rotation speed. The resulting water cloud perfectly captures all unfiltered dirt. Thus, thanks to the separator, the purification of the outgoing air is provided by 99.97 percent.
Recommendation. Be sure to inquire about the number of filtration stages available with your washing vacuum cleaner. After all, your favorable state of health and health will directly depend on this.
Due to the use of aquafilters, the design does not need replaceable dust bags, it is capable of humidifying the air, deodorizing it (for this, a special aromatizing liquid must be poured into the unit first). But there is one drawback - after each cleaning, the aquafilter must be rinsed and dried.
