In detail: do-it-yourself repair of a mulinex bread machine; replacement of an oil seal from a real master for the site my.housecope.com.
In the life of many bread makers, there comes a moment when the bucket starts to leak. You can, of course, ignore the problem for a while, but over time it only gets worse. The shaft wobbles more and more, the blade scratches the bottom of the bucket, and then the shaft just falls out. This is the lot of most budget bread makers. Panasonic do not suffer from such things, but their one bucket is more expensive than an ordinary bread maker.
What are the options for a way out of this situation?
1. Throw this bread maker and go buy a new one.
Probably, this is the reaction of users that manufacturers are counting on. The resource of work is laid such that it will last for a little more than the warranty period.
Advantages: the easiest way.
Disadvantages: expensive and new flour of model selection.
Advantages: more budgetary than the previous one.
Disadvantages: sometimes even the same model of bread maker is equipped with different buckets. the mount may not fit, the size of the seat. The easiest way is to contact a service center, but it will cost more than buying it yourself.
3. Repair the bucket yourself.
Pluses: The most budgetary solution. After repair, the bucket becomes "eternal": you can maintain its performance as long as you like. Until you get bored.
Disadvantages: Requires the presence of more or less straight arms or the owner of those among friends. You also need some tool and basic skills to work with it.
I want to tell you about this third option in more detail.
The first step is to separate the bucket from the base with the shaft. Perhaps the most difficult operation in this matter, as it takes some care not to damage the bucket. But in any case, it will be possible to return to option number two.

I almost forgot, you need to put the risk on the base and the bucket, so that later you can put everything together correctly.
Somehow the rivets need to be removed. If you have a drill or screwdriver, you can drill them out.
You can grind off the protruding parts of the rivets with a file (file, grinder, sharpener), and knock them out.
After that, the lower part is easily detached.
We take out the worn out oil seal and measure it to order a new one. You can measure not the oil seal itself, but the shaft diameter (usually 8 mm) and its seat (18-20 mm).
The second difficult operation is the replacement of the metal-graphite sleeve. At the factory, it is inserted "hot", so it is impossible to knock it out without damaging the silumin base. I made cuts in the bushing with a jigsaw and it can be easily removed. This can be done with a file (long) or with a narrow hacksaw blade.
We measure the diameter and height of the sleeve.
And neatly, with light taps, we hammer in a new sleeve. It should protrude 1 mm from both sides.
If the “butterfly” is not riveted at the bottom of the shaft, then it is worth replacing it too. Then we get the "new bucket" state. You can also rip off a riveted butterfly, but this requires a slightly higher level of skill.
If the shaft falls out, then you need to buy an 8 mm retaining ring.
And here are the 10 mm M5 bolts. With washers, grovers or self-locking nuts.
Insert the shaft and secure it with a retaining ring.
Lubricate the holes for the bolts and around the oil seal with silicone.
We connect the bucket with the base according to the pattern and tighten the bolts.
PS: The bushing and the oil seal will cost about 60 hryvnia plus shipping. Shaft - 50-100 UAH.
It is not difficult to repair a bread machine, the main thing is to correctly approach this process. A home bread machine is a complicated device, but some breakdowns can be easily fixed on your own without taking it to a service center. The most common malfunctions of simple parts. If used correctly, a home bread maker will last for a long time. It is a very reliable household appliance. But, over time, repairs are still needed. This is due to wear of the device parts, or there is a malfunction in the electronics (software).Some breakdowns can be repaired by hand. This applies to mechanical parts. The control circuit, sensors, all these problems are best left to the master to solve if any part is broken.
Most often, the following malfunctions occur:
- Failure of the heating element;
- Damage to the thermal sensor;
- Engine breakdown;
- Failure in the control program;
- Cover problems;
- Breakage of the bowl.
If the heating element breaks down, the bread stops baking altogether. This can be checked by disassembling the device and checking the heater with a tester. If the breakdown is confirmed, the heating element must be replaced. The temperature sensor regulates the temperature during baking. Its malfunction leads to the fact that the bread either burns or is not baked. Replacing the thermal sensor is not difficult.
If the motor of the bread maker breaks down, the agitator remains stationary, and when turned on, its operation is not heard. In this case, it is better to consult a specialist.
Failure in the control program can be determined by the strange behavior of the device. The signal about the end of work turns on at the beginning of baking, some buttons on the control panel stop working, all this is the cause of the breakdown of the program module. Failures of the cover of the device often occur. It is not tight, or vice versa, it closes very tightly. In this case, you need to make sure that nothing interferes with the closure of the lid. If so, then the entire cover needs to be replaced. A common cause of bowl breakage is oil seal or bearing wear. If the gland is damaged, the bucket of the bread machine leaks, and if the shaft is jammed, the point is in the bearing.
To understand the cause of the malfunction of the device, it must be disassembled. Having decided to disassemble the bread maker, it is very important to carefully study the instructions and the diagram of the household appliance. Bread makers do not fundamentally differ from each other in their structure. The design of the Redmond, Saturn, Liberton or Moulinex device practically does not differ from Kenwood or Combustion.
The bread maker consists of:
In order to properly disassemble the bread maker, you must read the instructionsAn electric motor is installed in the baking chamber, which rotates the shaft in the baking bowl, heating elements (heating elements) and a coupling. A non-stick baking dish is located in the baking chamber. There is a kneading spatula at the bottom of the bowl. It connects to the shaft. From the outside, the shaft is attached by means of a coupling with a motor.
With the help of a temperature sensor, the desired temperature is maintained during the baking process.
The choice of parameters, switching on and off the device is carried out using the control panel. The display is used to display information. Dismantling the bread maker begins with removing the cover of the device. Then you need to detach the panel. It is secured with bolts and plugs. Carefully unfasten the ribbon cable from the board, and then you can remove the bottom cover. Then we take out the heating element. Thus, the bread maker is divided into a body and a casing.
Some models, for example, Orion, are problematic to disassemble. The motor and belt in them are at the bottom, and in order to get to them, you have to disassemble the entire bread maker. After repairing and replacing the necessary parts, the bread maker must be reassembled in the reverse order.In order to assemble everything correctly, and not to get confused in the bolts and screws, they immediately need to be laid out in different boxes, and remember the order in which the device was disassembled.
During the operation of the bread makers, high temperatures act on the gland, it gets wet when washing the bucket, and dries up in a calm state. This leads to a loss of elasticity and elasticity of the rubber, and the oil seal breaks, the bucket of the bread machine begins to leak. Moisture gets on the bearing and starts to rust. Do not delay the repair of the bread maker. This can lead to more serious problems. Replacing the bucket with a new one will not be cheap, and you can change the bucket oil seal yourself.
Before you start replacing the oil seal, you should prepare the necessary tools and materials for workFor repair you will need:
- New oil seal;
- Retaining ring (must match the shaft diameter);
- Graphite grease;
- Tools to disassemble a bucket of bread maker.
We unscrew the fasteners of the base of the bowl. The shaft is attached to the bottom in the bread maker's bucket with retaining rings. Remove the shaft retaining ring. Carefully knock out the shaft with the bearing and the oil seal through a wooden support. Remove the bearing from the shaft.
We remove dirt and rust from the shaft. It is better to use alcohol for this.
Lubricate the shaft with graphite grease. Next, we put the bearing back on the shaft. Then we install it on the bottom of the bucket, and fix it with a retaining ring. We install a new oil seal from the inside of the bowl into the groove around the shaft. We turn the bucket over, and fix the clutch with a lock washer. That's it, now you can check the work of the bucket.
Problems with touch controls are very common. The control buttons on the panel stop working and an error is displayed on the screen. These unpleasant effects are due to moisture getting under the film. You can deal with such a problem yourself.
In order to properly repair a baking machine, experts recommend performing all actions step by step- Place the bread maker on a flat surface.
- We clean it from fat, and peel off the panel. This should be done very carefully so as not to spoil the appearance of the device.
- Pry the sticker with a knife and carefully pull it up.
- Do not forget about the loop, on the LG bread makers it is on the right.
- Then carefully wipe the contacts with a soft cloth. They are located on the body of the bread maker and on the back of the control panel.
We use alcohol for cleaning. Wipe gently and thoroughly to get rid of dirt and grease that has got on the contacts. In order to prevent dirt from clogging up under the control panel during further operation, you can stick double-sided tape on the body along the perimeter of the panel-body connection.
After cleaning the contacts, close the touch panel. Checking the operation of the control panel. Typically, such repairs bring the panel of the bread maker back to life, and the buttons begin to respond to pressing.
For many, bread makers have long become indispensable helpers. Modern household bread makers are compact and fit easily in a small kitchen. A wide range of these household appliances allows you to purchase a model that is optimal in terms of price and performance. But, despite the variety of brands and models, bread makers have a similar principle of operation, and are assembled from the same parts.
The procedure for disassembly and repair is the same for almost all household bread makers. And many malfunctions can be dealt with on their own at home. Very often, the cause of a device malfunction is the breakdown of simple parts. It is quite possible to repair or replace them with your own hands and without contacting a service center. This will save money and time, because it is very difficult to do without the usual fresh bread baked according to your own recipe.
1. Note in which position the lower part of the bucket is attached!
2. We drill out aluminum rivets and knock them out.(It is best to use a 8 or 9 mm drill bit)
We will not bring it through! And only a rivet hat.
3. Remove the lower part of the bucket, gouge out the remnants of the oil seal, remove the retaining ring, remove the shaft from the bushing.
4. Using the tools at hand, knock out or draw out the sleeve.
IMPORTANT: Do not knock out the sleeve by simply placing the bottom of the bucket on the table! The knitting needles break off very easily and the bucket can then be thrown away. In the picture, a gear from a perforator is used, its inner diameter is slightly larger than the outer diameter of the sleeve, bearing 6203 is also good, but it is too low, so you need 2 of them.
5. After disassembly, we measure the parts as there are 5 types of oil seals, and there are 5 types of bushings.
6. Putting it up in the reverse order. We insert the sleeve. Insert the shaft into the sleeve and fix it with a retaining ring. We put on the oil seal on the shaft and put it in the seat. Apply sealant in the middle of the gland seat without smearing it.
7. Putting in place the bottom of the bucket, the sealant will fill the voids.
8. Instead of rivets, we use M5 stainless steel screws.
Next, consider the repair of Moulinex and Kenwood buckets.
We put a mark and drill out the rivets.
The main difference from the Chinese ones, in branded bread makers, is a silicone gasket between the bucket and the bottom.
When assembling such a bucket, the use of sealant is not required.
Another option is how to remove the bushing.
Even if the rivets were inside the bottom of the bucket, then the screws up to 10 mm long will not interfere.
A malfunction at a home bakery can take you by surprise. It can, of course, be taken to a service center, but some malfunctions that have arisen in your bread maker can be eliminated by yourself.
The following breakdowns are most often found in stoves:
- malfunction of the thermal sensor;
- burnout of the heating element;
- software failure in the control module;
- the electric motor is out of order;
- the belt slipped off;
- no power supply;
- faulty reverse relay;
- breakage of the ingredient bucket.
Other breakdowns inherent in other models and brands are not excluded, because there may be differences in design features.
The quality of the baked bread depends on the correct operation of the temperature sensor. If the thermostat is faulty, the bread will burn, or vice versa, it will remain unbaked. It is this sensor that regulates the temperature in the bread maker during the baking program. The figure below shows, for example, what the thermal sensor of the Kenwood Bread Maker looks like.
Thermal fuses are often located near the thermistor. They do not allow the temperature to be exceeded above a certain one, if the thermostat fails.
After disassembling the baking unit, it will not be difficult to find these parts by their external signs. It will also be easy to replace them with new ones, having previously bought them on the Internet or at a service center.
It is very easy to suspect that the heater is not working: the bread simply will not be baked... In order to check this, it is necessary to disassemble the device:
- unscrew the screws at the bottom of the stove and inside it by opening the lid;
- then carefully disconnect the bottom from the case without breaking the wires;
- disconnect the wires from the terminal block;
- you will see a large metal tubular ring.
This is the heating element (tubular electric heater). In some models of bread makers, it may be located inside an iron bucket container. It can be checked for burnout tester... If the burnout is confirmed, it must be replaced with a new one.
If your bread oven began to behave strangely: some buttons stopped turning on, a signal for the end of baking appears, when it has just begun, this may signal a breakdown of the software module. Unfortunately, you cannot repair bread makers with such a breakdown on your own. This should be done by qualified personnel from service center... Otherwise, unknowingly, you can aggravate the malfunction and it will be more difficult and more expensive to repair the module.
This breakdown is easy to determine. If you turn on the machine, and the mixer does not start to rotate and you do not hear the sound of the engine running, this means that the rotary movement from the pulley - the electric motor is faulty. Repair of this unit of the unit, as mentioned above, must be carried out by a master.
In the case when, after turning on the apparatus, the noise of a running motor is heard, but the paddle does not spin, or when the ingredients are poured, they do not mix well, then the reason for this may be wear or slippage of the toothed belt from the pulley.
The belt of the bread machine can be found by removing the bottom of the machine. By wear rate the belt of the drive of the bread machine is determined whether it needs to be replaced with a new one.
A common reason the bread maker simply won't turn on is a lack of power. First you need to check electrical plug and the cord itself. Next, you have to check the power supply, as a rule, a pulse one. It has its own fuse. But you should not rush and change it. If, after connecting a 100 W light bulb to the circuit, it lights up, then urgently turn off the power to further search for a short circuit. When the power supply is working, the light should not glow, it can only blink. The power node usually consists of rectifier and capacitor... This is where the malfunction lies.
Do-it-yourself bread maker repair in this case is possible if you are at least a little versed in the radio business.
In some inexpensive units, the paddle (agitator) is removed from the shaft. For this, a hook is included with the apparatus for extracting it from the bread. But there are models when the stirrer is folded. If after baking on the product you find an oar print, then the reverse is faulty.... Repair to eliminate this trouble of the bread maker should take place with the participation of a specialist.
Repair of a bucket of a bread machine due to failure bearing and oil seal you can make it yourself. Symptoms that this is the exact reason are as follows:
- there is a small leak from the container;
- wedging or complete wedging of the shaft.
For a better understanding, the repair of a bread machine is shown below. LG do it yourself about replacing the bearing and oil seal (unit model LG HB-155CJ).
A metal plate 1-2 mm thick will need to be placed on the bearing shaft.
To continue, you will need to purchase necessary spare parts: 608th ball bearing (outer diameter 22 mm, inner diameter 8 mm, height 7 mm) and special white seal.
Further, in reverse order:
- Slide the bearing onto the shaft and install the retainer.
- Carefully press the bearing into its seat. It should be refrigerated before installation. You can also heat the bucket. Impacts when pressing in are not allowed.
- Now you can fix the shaft with a special washer-stopper.
- In conclusion, you will need to install an oil seal. The repair of the bread maker's bucket is over!
Not all possible breakdowns of the bread baking machine were considered, since it is impossible to list them completely, and it depends on the characteristics of models of different brands. However, you can fix some faults using this manual yourself.
