The device of the home breadmaker to masters will remind the slow cooker, the fundamental differences are few. Asynchronous( or synchronous) capacitor motor, working for a long time while it is kneaded. It was not possible to make small sizes, in the technical compartment of the home bread maker the motor takes up the lion's share of the space. The rest eats electronics. The relay circuit for forming the voltage of the heating element of the home breadmaker, which operates according to the programmed program, guided by the temperature sensor readings and a timer. More common electronic models. Mechanical temperature switches are rare as ticking timers. It is clear that the program is contained in the memory of the electronic circuit, less commonly recorded by an advanced user. Repair the bread machine with their hands touches the mechanical part, sensors, control panel. With a microchip, the master will break his leg, although it is necessary to inspect the capacitors, tracks, resistors.
Bread Maker Device
It's time to discuss the bread machine device. The master, deprived of the simplest information, must avoid initiative actions!
Inside the home bread maker a parallelepiped bowl preparing bread. At the bottom there is a paddle that makes the batch. Beginners bakers are interested in the location of the blade when the home breadmaker gives the table a fresh loaf. The paddle is folded. Methods of implementation are different, sometimes the motor performs a short reverse. Most of the washing machines engines contain collector, speed transmits gear. The paddle of the home bread maker is driven by a strap covering the pulley. The collector motor reverses by changing the sequence of the windings. The poles begin to attract, and not repel. Switching is carried out by the relay. Asynchronous motor changes the direction of rotation of the field inside the stator. Achieved by proper switching of the windings.
Shifting is harmful to both engine types. The electronic board of the home bread maker, implementing the program, will prevent speed fluctuations. Temperature is controlled by the sensor. There is a thermistor( thermocouple), the slope of the characteristic is stored in the memory. The time intervals of the home bread maker are measured by a quartz oscillator, allowing the device to know the sequence of actions every second.
The design employs a loopback heater, covering the bowl perimeter. The bottom of the working compartment does not apply. Thermal insulation measures will create inside the conditions of the oven. Home bread maker can not be called a quick device. Slowly the heating element heats the air inside the compartment, a steel( aluminum) bowl. The non-stick coating prevents the loaf from burning, observing the window of the lid, the cook monitors the process phase. The lid keeps the heat tight, thanks to a rubber gasket - a uniform heating of the compartment. Bread is baked, not fried.
Homemade bread machine allows you to adjust the color of the crust. We believe the effect is achieved by maintaining the desired baking temperature. The bread comes, the hot oven gives the crust a dark shade. Covering non-stick bowl. Teflon, ceramics, marble - a marketing gimmick, synonymous words. The content of natural material reaches 5-10%.Only a real ceramic bowl will provide the family with safe products( for the multicooker they sell).Teflon, after a couple of years is erased, it will not work out.
The cover of advanced models contains a dispenser. A kind of device that allows software( according to the timer) to fill the dough with nuts, raisins, and other ingredients. Works dispenser, managed teams of the chip. The master will check the slamming device if it knows the applied voltage.
. Typical malfunctions of
bread makers. At times, the paddle begins to sway, gnash, stop. Homemade bread machines contain graphite liner. Carbon lubricant successfully withstands heat, is harmless, is used appropriately. Little is a health hazard. A sharp blow the liner is able to split, crumble, a long operation wears the material. Take the trouble to regularly check the condition of the paddle. There are problems - order a new spare part. If the bottom of the working compartment is wetted by water, the bearings of the bowl are worn out. Ceramics have a limited life, too thick dough makes the material unusable.
Repair of the bread machine's bucket is limited to eliminating leaks in the area of the rolling joint. Removing the axis of the paddle, the master unscrews the bottom cover. The screws are scattered randomly, there is a probability of being inside the working compartment. The pulley is fastened with a nut, there are non-separable joints. The main types of faults are typical:
- Bread badly baked:
- Broken heater. Dough will not rise. There will be a lump, the temperature accelerates the fermentation of yeast, the processing of sugar. The dough is raw.
- Temperature sensor defective. Thermocouple, thermistor. Algorithm action repairman involves the study of technical documentation. Lack of information forces to grab a multimeter. Thermocouple gives EMF( tens of millivolts), thermistor changes resistance.
- Faulty programmer, electronic board. Rarely stand mechanical timers-relays( typically microwave);servo drive( washing machine).The control of the home bread maker is taken by electronics - the programmer-performing mechanism in one person. Repair follows the general scheme. Assess the condition of the mounted elements, the tracks of the printed circuit board
- The loaf bears the imprint of a paddle, forgot to take shape. Faulty reverse relay. Broken engine home bread maker, not knead the dough. Rarely stuck mechanism oars.
- Paddle blocked:
- Engine failed, diagnosed dead dead.
- Jumped off the pulley belt. Paddle rotates by hand unusually easy.
- Oars have to help with the hand, starting the rotation. The failure of the engine of the home bread maker begins. The reason is explained by ill-conceived mechanics. Lack of lubrication, belt problems. Homemade breadmaker warranty - puzzle service department. Until the bakery is completely broken. The problem affects the bowl, gearbox, tightly stretched belt does not bring to good in any case.
A typical breakdown is the lack of power. You should start with a cord, move up, assessing the performance of the circuit. Electronic stuffing requires a switching power supply. The stabilizer is equipped with a fuse, should ring the integrity of the element. Having found malfunctions, hesitate to put a new one. Fuse one does not burn. Try turning on a 100 watt bulb instead. If it is lit after turning on the power, rather pull the plug out of the socket, look for the problem further. Unfavorable mode can ruin the PCB.It is necessary to find the cause of the short circuit of the home breadmaker, and then put the fuse.
In a good power supply, the light should not be on at all, it blinks and goes out. Continue to repair the bread machine yourself until this condition is fulfilled. The simplest power supply includes a capacitor and a rectifier, and often there is a breakdown.
The leading role is assigned to the control panel. A sensor consists of a film on which electrodes are applied. The second half of printed wiring on the caseEveryone who looked into the control panel of the TV or other household appliances, saw the meanders of copper. If moisture is ingested, unpleasant effects will also occur, but fatal damage does not occur. It is necessary to clean the installation. The film with the controls is relatively easy to peel off. It is important not to break, so that the product does not lose its presentation. When cleaning, try not to use abrasive, it would be ideal to do with acetic acid, alcohol and other reagents to remove the oxide film and other dirt.
Specific breakdowns of home bread makers
Some designs have typical design flaws. Many devices are made simultaneously for Europe, where the standard voltage is 230 V. However, the design features do not take into account that stability in Russia is lower. This causes a very bad, interrupted operation of the home bread maker. Before buying, search the forums for relevant information, and if there are complaints, then choose another model.
Carefully also read the instructions, so as not to make mistakes for beginners and not to look for what might break:
- The signal to the chef to add raisins, dried apricots, nuts in the dough is perceived as the end of the cycle. And interpreted as a malfunction.
- Excessive amount of water results in a looseness that does not want to take the normal form of a kolobok and rise.
- Too dense kneading quickly disables the mechanical part of the home breadmaker, while the quality of the rich products does not improve.
And remember the main thing: independent repair of the bread machine begins where the warranty ends. If the device is expensive, or there are no skills to handle it, then it is better to entrust the matter to professionals. But to monitor them already need to closely. This is Russia, everyone who can only cheat here, if there is nothing behind it. In search of spare parts, go through the nearest artisan workshops. Because in the certified service center nothing breaks off. In an effort to save the master can sell some spare parts, an old engine.
