DIY bork x500 bread maker repair

In detail: DIY repair of a bork x500 bread machine from a real master for the site my.housecope.com.

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 at the same time you do not hear the sound of the engine running, this means that the rotary motion 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 device, 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, impulse. 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).

  • It is required to get the bucket and remove the ring, which is a stopper for holding a metal washer with plastic lugs on the shaft. At this stage, the ring set for fixing the bearing you can leave it alone. Image - DIY bork x500 bread maker repair
  • The next step is to pull the bearing out of its seat. You cannot knock on the bucket, as it is fragile and can crack. It would be correct to use a special two-fingered puller... The stripper is fixed in a position where its hooks are well fixed in the grooves on the bucket body. Image - DIY bork x500 bread maker repair

    A metal plate 1-2 mm thick will need to be placed on the bearing shaft. Image - DIY bork x500 bread maker repair

  • After that, start screwing in the axle of the device until the oil seal from the bearings falls out from the inside of the bucket. The next photo clearly shows the poor condition of the parts. Image - DIY bork x500 bread maker repair
  • Now you can unclip the bearing. Image - DIY bork x500 bread maker repair
  • Next, you need to remove the defective part from the shaft using the same puller and clean it from dirt using alcohol (do not use solvents and gasoline to clean the shaft). Image - DIY bork x500 bread maker repair
  • 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:

    1. Slide the bearing onto the shaft and install the retainer. Image - DIY bork x500 bread maker repair
    2. 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. Image - DIY bork x500 bread maker repair
    3. Now you can fix the shaft with a special washer-stopper. Image - DIY bork x500 bread maker repair
    4. In conclusion, you will need to install an oil seal. The repair of the bread maker's bucket is over! Image - DIY bork x500 bread maker repair

    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.

    It is forbidden to write answers that do not carry any benefit to the questioner from the series: “bring to the service”, “contact the ASC”, “unprofitable”, etc. Answers like these will be considered a rating cheat, the answers will be deleted, and the account will be blocked.

    If you undertake to help people, answer fully. Explain why, if you recommend, for example, reflashing your phone, then write how to do it. If you write that repairs are unprofitable, explain why.

    The device of a home bread maker will remind the masters of a multicooker, there are few fundamental differences. An asynchronous (or synchronous) capacitor motor that runs for a long time while the batch is in progress. It was not possible to make small sizes, in the technical compartment of a home bread machine, the motor takes up the lion's share of the space. The rest is eaten up by electronics.A relay circuit for generating the voltage of a heating element for a home bread machine, working according to the laid down program, guided by the readings of the temperature sensor, and a timer. Electronic models are more common. Mechanical temperature switches are as rare as ticking timers. It is clear - the program is contained in the memory of an electronic circuit, less often it is entered by an advanced user. Do-it-yourself bread maker repair concerns the mechanical part, sensors, control panel. By splitting microcircuits, the master will break his leg, although it is necessary to inspect the capacitors, tracks, resistors.

    It's time to discuss the structure of the bread maker. Deprived of the simplest information, the master must avoid proactive actions!

    Inside the homemade bread maker is a parallelepiped bowl that prepares the bread. At the bottom there is a kneading paddle. Novice bakers are interested in the location of the blade when a homemade bread maker presents the table with a fresh roll. The paddle folds up. The implementation methods are different, sometimes the motor performs a short reverse. Most washing machines contain collector motors, the speed is transmitted by a gearbox. The paddle of a homemade bread machine is driven by a belt that wraps around a pulley. The collector motor performs reverse by changing the sequence of switching on the windings. The poles begin to attract rather than repel. Switching is carried out by relays. An induction motor changes the direction of rotation of the field inside the stator. This is achieved by correct switching of the windings.

    For both types of engines, sudden changes in motion are harmful. The electronic board of the home bread machine that implements the program will suppress speed fluctuations. The temperature is monitored by a sensor. There is a thermistor (thermocouple), the slope of the characteristic is stored in memory. The time intervals of the homemade bread maker are measured by a quartz oscillator, allowing the appliance to know the sequence of actions every second.

    The design uses a loop heating element that covers the bowl with a perimeter. The bottom of the working compartment does not touch. Thermal insulation measures will allow you to create an oven environment inside. A homemade bread maker is not a quick fixture. The heating element slowly heats the air inside the compartment, the steel (aluminum) bowl. The non-stick coating prevents the loaf from burning, observing the window of the lid, the chef monitors the phase of the process. The cover keeps heat tightly, thanks to the rubber gasket - even heating of the compartment. The bread is baked, not fried.

    A homemade bread maker gives you the ability to adjust the crust color. We believe that the effect is achieved by maintaining the desired baking temperature. The bread will come, the hot oven gives the crust a dark shade. The coating of the bowl is non-stick. Teflon, ceramics, marble - a marketing gimmick, synonymous words. The content of natural material reaches 5-10%. Only a real ceramic bowl will provide a family with safe products (they sell for a multicooker). Teflon, after a couple of years is erased, cannot be restored.

    The lid of the advanced models contains a dispenser. A kind of device that allows you to programmatically (according to a timer) fill the dough with nuts, raisins, and other ingredients. The dispenser is operating, controlled by the commands of the microcircuit. The master will check the slamming device if he knows the supplied voltage.

    From time to time the paddle starts to swing, gnash, and stops. Homemade bread makers contain a graphite liner. Carbon grease successfully resists heat, is harmless, and is used appropriately. Poses few health risks. A sharp blow the liner is capable of splitting, crumbling, long-term operation wears out the material. Take the time to check the oar regularly. Problems noticed - order a new part. If the bottom of the working compartment is wet with water, the bowl bearings are worn out. Ceramics have a limited life, too thick dough makes the material unusable.

    The repair of the bread maker's bucket is limited to the elimination of leaks in the movable joint area. Removing the oar axle, the master unscrews the bottom cover.The screws are scattered randomly, there is a possibility of being inside the working compartment. The pulley is fastened with a nut, there are non-separable joints. The main types of malfunctions are typical:

    • Bread does not bake well:
    1. The heating element has broken. The dough will not rise. Will lie in a lump, the temperature accelerates yeast fermentation, sugar processing. The dough is raw.
    2. Temperature sensor defective. Thermocouple, thermistor. The algorithm of the repairman's actions involves the study of technical documentation. Lack of information forces you to grab a multimeter. The thermocouple gives an EMF (tens of millivolts), the thermistor changes the resistance.
    3. Defective programmer, electronic board. Rarely are mechanical timers-relays (typically microwave oven); servo drive (washing machine). The home bread maker is controlled by electronics - a programmer-executing mechanism in one person. The repair follows a general scheme. The condition of the hinged elements, the tracks of the printed circuit board is assessed.
    • The loaf bears the imprint of an oar, forgot to fold. Reverse relay defective. Broken motor of a homemade bread maker, will not knead the dough. Rarely does the oar mechanism stick.
    • Paddle locked:
    1. The engine is out of order, diagnosed by deathly silence.
    2. The pulley belt came off. The paddle rotates by hand with unusual ease.
    • The oar has to be helped by the hand, starting the rotation. Failure of the home bread machine engine begins. The reason is explained by ill-conceived mechanics. Lack of lubrication, belt problems. Home Bread Maker Warranty - Challenge Customer Service. Until the bakery broke down completely. The problem affects the bowl, the gearbox, a tightly tensioned belt does not do good in any case.

    Lack of power is a typical breakdown. You should start with the cord, move up, assessing the performance of the circuit. Electronic stuffing requires a switching power supply. The stabilizer is supplied with a fuse, you should ring the element for integrity. If you find a malfunction, hesitate to install a new one. The fuse alone does not blow. Try switching on a 100W incandescent light bulb instead. If it lights up after turning on the power, quickly unplug the plug from the outlet, look for the malfunction further. An unfavorable mode can ruin the PCB. It is necessary to find the cause of the short circuit of the home bread maker, and then put on the fuse.

    In a working power supply unit, the light should not burn at all, it will blink and go out. Continue DIY repair of the bread maker until this condition is met. The simplest power supply includes a capacitor and a rectifier, and this is where the breakdown often lies.

    The leading role is assigned to the control panel. The sensor consists of a film on which electrodes are applied. The second half of the PCB assembly on the case. Everyone who looked into the remote control of a TV or other household appliances saw meanders made of copper. If moisture gets inside, unpleasant effects will also occur, however, fatal damage does not occur. The installation needs to be cleaned. The control film is relatively easy to peel off. In this case, it is important not to tear so that the product does not lose its presentation. When cleaning, try not to use an abrasive; it would be ideal to do with acetic acid, alcohol and other reagents to remove oxide film and other dirt.
