In detail: do-it-yourself repair of the Tefal fv9447 iron from a real master for the site my.housecope.com.
Before proceeding with the repair of the iron, it is worth examining its design. Today it is difficult to imagine any housewife who does not have an iron. This indispensable assistant in the household is present in almost every home, but sometimes it happens that it breaks down. You can, of course, immediately buy a new device and not suffer. And you can try to repair it with your own hands, because this is within the power of any person who is a little familiar with the device of these electrical appliances.
Today the market is full of irons from a wide variety of manufacturers - Tefal, Brown, Elenberg, Maestro, Atlanta, Saturn, Philips, Scarlet, Vitek - while the device of this technique remains the same. How does this device work and what does it consist of?
Iron components:
The sole, where the heating element is built in - sometimes there are holes in it, if the iron has a steamer;
Thermostat equipped with a knob to adjust the heating temperature of the sole;
Water tank, if the iron "knows how" to steam;
Water sprinkler;
Steam supply regulator;
Power cord for connecting the device to the network.
The electrical circuit of such irons as Braun, Bosch, Polaris, Tefal, Vitek looks like an electrical circuit of a kettle or heater. And this is not surprising, because the circuits of these devices are not much different.
The iron diagram can be downloaded on the Internet and printed on a printer for ease of use.
In any iron, regardless of its brand (it can be at least Bork 1500, Polaris, Magnet, Feya 128, Redmond, Ladomir, Moulinex, Philips Azur, Vitek 1209, Bosch or Tefal Superglis) there are main nodes:
Heater;
Thermal fuse;
Cord with a plug;
Temperature regulator.
The principle of operation of electric irons is as follows: to turn it on, voltage is applied to the heating element located in the sole of the device. In many modern irons, for example, Roventa, powerful heating elements from 1000 to 2200 w are used. It is worth remembering and not to overheat such a unit.
However, to avoid this, a thermostat is built into the circuit, on which the setting of degrees depends. Temperature control is carried out by turning the wheel in different directions. If you do it clockwise, the temperature will increase.

An important element of ironing is a fuse, which, when high temperatures are reached due to a malfunction, opens the contacts of the device, thereby turning it off.
When the iron does not work, does not turn on, leaks, cracks, blinks or does not heat up, many housewives begin to panic, asking why this happened.
The main reasons why the iron breaks down:
The thermostat has broken;
The terminals are gone;
The cord broke;
The contacts in the thermostat are oxidized;
The fuse is out of order;
The valve does not work.
One of the frequent breakdowns of irons is a broken cord. The fact is that when using an iron, the cord is constantly bent, which leads to chafing. If this happens, the device may not turn on, and the sole of the device may not warm up well.
By the way, you can understand that something is wrong with the iron long before it breaks down. Usually, a blinking red light signals a problem that has arisen, which, if the iron is in good working order, burns evenly.
For any damage to the irons, you need to start the repair by checking the cord. To find out exactly whether he is the "culprit" of the malfunction, you need to ring him. You can check this with an ordinary tester or multimeter.
To be sure, it is better to wiggle the cord during operation, especially in problem areas. If the beep of the multimeter begins to interrupt, it is better to replace the cord.
In the event of a malfunction of the cord next to the plug, you need to change it.
If, in order to fix the iron, you still need to disassemble it, you will have to do it. And it's okay that at home.
For this you will need:
Screwdriver Set;
A wide knife or unnecessary plastic card for prying the latches;
Multimeter or tester;
Soldering iron - if some elements are replaced;
Insulating tape;
Pliers;
Sandpaper.
It all starts with removing the back panel, which has several screws. Usually one is located on the nose of the instrument, and the other can be in the area of the cord. A screwdriver will help us to cope with them. But it should be borne in mind that in addition to screws, there may be latches or the screws themselves are hidden under the casing. For example, Philips “hides” the screw under the handle for adjusting the steam, and “Brown” under the nozzle cover (it can be removed by pulling it towards you). To unscrew the screw from Phillips, you need to turn the handle all the way to the left, and then pull it up.
Then, after unscrewing all visible fasteners, you need to pry the cover with a card or the end of a knife, thus separating the cover from the case.
We disassemble further. Under the cover there is a terminal block to which the cord is attached. If the problem is in him, then you can not go further. But if everything is in order, the analysis continues.
To disassemble the iron, you must have a screwdriver
In some irons, such as Philips or Tefal, there are also bolts under the lid. They also need to be unscrewed.
Actually, the devices of each manufacturer have their own characteristics, but the general parsing scheme is about the same, be it Bosch Sensixx Comfort, Philips Azur or Powerlife, Tefal Supergliss 3530 or Ultragliss, Braun Texstyle, Philips Easy Care, Tefal Aquaspeed 150, Maxwell 3045, Elenberg, Viconte, Bork i500, Domotec, Bosch da70, Polaris Pir 1833.
Next, you need to remove the temperature regulator and steam outlet. To do this, the steam button and the dial of the regulator are pinched with your fingers and pulled up. If there are latches, they must be squeezed out.
Rowenta irons and some Scarlett models may even have bolts on the handle. If they are, then they also need to be unscrewed. There may be screws under the removed parts that need to be unscrewed and then removed the upper plastic parts.
You need to unscrew the fasteners until the body is completely detached from the sole. But the further device and disassembly of the desired part already depends on the specific model of the iron.
When the iron breaks down, it needs to be repaired. The person fixing the iron, after disassembling the device, can begin to find out the reasons why this happened.
Perhaps the matter lies in the breakdown of the heating element. Verification is needed to verify this. For this, the rear cover of the unit is removed, after which it is necessary to look at the conclusions of the element itself. If the light or indicator lights up, but the device itself does not heat up, most likely the spiral has broken. By the way, if the heating element breaks down, it is better not to change it, but to immediately buy a new iron, since the cost will be almost the same.
How to check the health of the thermostat:
Disassemble the iron body;
Find a thermostat - it looks like a plate with contacts and a plastic pin;
Inspect the contacts of the regulator - in a cold state, they should be all closed;
If everything is in order with their appearance, it is worth checking them with a multimeter - if the device shows "0", everything is in order, and if "1" - the problem is in the contacts.
If, nevertheless, it is found that the contacts are not in order, most likely they are burnt. In this case, you need to clean them. For these purposes, you can use fine-grained sandpaper or a nail file. Care must be taken, as the contacts are very sensitive and should not be strongly bent.
If the iron does not turn off, there is an option that the contacts have fused or somehow adhered. In this case, they need to be disconnected and mobility restored, being careful not to distort the details. If this cannot be done, the option remains - to replace the old unit by writing it off, if it is at the enterprise.
In the same place where the thermostat is located, there is also a thermal fuse. This device, which is responsible for the degree of heating of the sole, burns out as soon as the temperature goes beyond the permissible limit. Usually "hidden" in a white tube protecting the mechanism.
How to check a fuse and what to do if it is blown:
First you need to find contacts and ring them - in working order, the fuse rings;
You can move the tube and ring it straight out in order to exclude a break in the connecting wire;
If the fuse blows out, you need to remove it, buy a similar one and reinstall it.
It is impossible to remove the fuse from the iron device: in a critical case, it will prevent a fire from occurring if the thermostat fails.
The node where the thermostat is located (for example, hf7520) can be single - or reusable. Mechanisms from the first group are triggered only once, after which they need to be changed.
When carrying out repair work, the iron must not be plugged in.
New technologies provide for the use of bimetal in the relay. Such elements can turn off the iron in a dangerous situation and then turn it back on. If a breakdown occurs for this reason, it is easier to remove the node, and the circuit itself is short-circuited by soldering, crimping or by switching the supply wires.
Another common problem is the breakdown of the steam generator in the UTP (irons with a thermostat and a steam humidifier). What if the appliance stops emitting steam?
In Bosch irons, this may be due to the fact that the button of the steam station is strongly pressed.
What to do in this case:
It is necessary to remove the back cover of the device, then carefully remove the buttons with which steam is supplied;
Next, the screw is unscrewed and the plastic handle is removed;
There are two pumps under the cover: one supplies water for the sprinkler and the other supplies liquid to the sole to form steam;
The steam pump is removed and examined - in its lower part there is a ball that sticks to the bottom due to scale;
To fix the problem, you need to push this ball back into the chamber and assemble the iron.
If steam does not come out, and there is water in the tank, the reason may lie in the clogging of the hole with salts. In this case, you need to make a solution of water and vinegar in the proportion: 1 liter of liquid - 1 glass of vinegar, into which you lower the disconnected iron. The water should cover the bottom of the iron.
Or you can 2 tsp. dilute lemon acid in 250 ml of boiling water and put an iron in such a solution. Then the container with the iron is heated to a boil. Then it turns off, and when it cools down, it heats up again. This should be done 3-4 times until the salts dissolve.
If water flows from the device instead of steam, there may be two reasons: improper operation (the regulator is incorrectly set and the sole does not have time to heat up to the degree of steam formation) or valve breakage. To make sure that the iron is dripping precisely because of the valve, you need to pour water, turn off the steam supply and shake it a little. If the liquid continues to flow out, the valve does not close the hole tightly due to the rubbing of the rubber gaskets.
When reassembling the iron, you can use a sealant to seal the soleplate and body together more firmly. As you can see, there is nothing particularly complicated here. Almost everyone can identify malfunctions and eliminate them. The main thing is that the repairing iron observes safety precautions when working with electrical appliances and knows how to use the necessary tools.
So, with the beginning of 2015, we are all quietly plunging into another economic crisis. Also, the attitude towards things that, in the event of a breakdown, would simply be replaced with new ones, changes smoothly. Now it has become costly and probably unreasonable to do this, especially if you show ingenuity, then a broken thing can be repaired. Moreover, the costs of repairs are not comparable, both with the cost of repairs and with the huge prices for a new thing. Marina, a reader of the Secret of the Master website, showed her engineering ingenuity and repaired her iron. She shares her secret of success with all of us.
A steam iron is an irreplaceable thing in every apartment and a breakdown of an iron, especially now, can greatly disrupt financial plans and cause a serious blow to the family budget.An annoying nuisance occurred from intensive use, the iron lost its important function of supplying steam due to a breakdown in the button for supplying steam.
Sometimes the hardest part of a repair is trying to disassemble the device without breaking it. Marina reveals to us the secret of the iron fasteners and, most importantly, shows us where and how to fix the breakdown.
Before proceeding with disassembly, you need to prepare the tool. Tefal uses sprocket screws. These screws are unscrewed with a screwdriver with an appropriate tip or a screwdriver with replaceable bits. It is easier to buy a bat in a tool store, but you can make it even more tricky to buy a set of screwdrivers in the “All for 40 rubles” store (today it is already called “All for 42 rubles”). A flat screwdriver from the kit will allow you to unscrew the sprocket screw.
Step 1. Find the first screw on the vertical support of the iron. See photo. We unscrew the screw.
Step 2. The second screw is located under the steam regulator. Carefully take it out and unscrew the second screw.
Step 3. The third screw is cleverly hidden under the buttons. Carefully pry the buttons with a flat screwdriver and take them out. We unscrew the screw.
Step 4. Remove the iron cover and see the destruction. The plastic tube on which the button rests has broken :(.
Step 5. Do not try to use superglue - it is not omnipotent. This glue can only hold the broken parts of the tube together. To restore the functionality of the iron, you will need a heat-shrinkable tube with a diameter of 4 mm. Purchase the handset from an electrical or radio store.
We cut off the heat shrinkage to the required length and put it on the broken tube with our own hands. If you have no experience with heat shrinkage, practice on the remainder of the tube. It is best to heat the tube with hot air (a household hair dryer will not work), but the flame of a lighter or the heat of a soldering iron will be enough. Do not expose the duct and plastic of the iron to direct flame! The tube should only be exposed to hot air. We heat the tube until it shrinks. We install heat shrinkage on the second tube.
Step 6. Assembling the iron in reverse order. Hooray! The Tefal Ultragliss Diffusion iron has been refurbished! Your prize is a working iron, saved money, time and a set of screwdrivers.
Many thanks Marina DvaMandarinafor the provided material for the repair of the Tefal iron.
For. in order to look neater and more pleasant for those around them, people from ancient times have tried to get rid of various folds and irregularities on their clothes. In the early periods of history, stones of a suitable shape, dishes filled with coals and other improvised means were used for this purpose. The electric iron, which has become ubiquitous today, was invented relatively recently.
It begins its history at the end of the nineteenth century, when the electric iron was first patented. Since then, the technique has undergone significant changes and modern Tefal brand irons are one of the most striking and vivid examples. However, even a technically reliable device deteriorates over time, which makes it necessary to repair it. The most rational solution would be to do it yourself, which will save money.
Considering the technical device and the characteristic features of the operation of electric irons, it can be noted that they are quite similar to another category of electrical appliances - a kettle. The main element of the design, without which the normal operation of the device is impossible, is the heating element, which has a power of about 1000-2200 watts.
For correct operation, the required voltage is supplied to it. However, in order to avoid overheating of the heating element and damage to clothes, manufacturers equip devices with a temperature controller with various modes available to the user.
For the vast majority of irons, the following features of work are characteristic:
When you turn a special round knob for clockwise adjustment, the operating temperature of the iron sole increases;
Switching the regulator on and off is accompanied by a special click;
The main element due to which the adjustment takes place is the bimetallic plate, which expands under the influence of temperature.
The system for supplying electricity to the appliance is quite simple and includes an electrical cord and a plug. Due to the design features, to repair the cord, you will need to disassemble the iron.
The design of Tefal irons involves a specific way of attaching the sole to the internal elements of the device... It is carried out both with the help of special latches and with the use of screws, which can be carefully masked. For this purpose, most often, they are placed under decorative plugs, as well as under a water tank. In order not to violate the integrity of the structure during disassembly, it is necessary to find all of them.
