Today, different household appliances are used for cooking, to perform certain functions and to simplify work in the kitchen. The multi-cooker is a versatile device, as it can perform various functions of cooking and frying food.
The device consists of many parts, and when one of them fails, the operation of the entire mechanism is disrupted. There are many reasons why the multicooker does not turn on.
Premature Shutdown
If the product is misused, a lot of food is loaded, the temperature is not maintained, or the wrong cooking functions are selected, this will lead to a number of breakdowns. Although the system has an intelligent process that controls the cooking time and mode, the system cannot recognize whether the products are inserted correctly and whether the correct processing step is selected.
If the amount of liquid is insufficient, the mass inside starts to burn on the bowl of the appliance. This may also be one of the options why the multicooker does not turn on. In most cases, the housewives themselves are to blame for breakdowns, because they choose the wrong modes or knock down the settings.
This can't be done. If there is no experience in using a multicooker, it is better to rely on the recommendation in the instructions and cook exclusively according to the book that came with the appliance.
Reason for disconnection
There are several options why the multicooker does not turn on. The first is a factory defect that did not prove itself during testing or before purchase. If the device is under warranty, you can contact the service center and fix the problem at the expense of the manufacturer. And also if there is mechanical damage to the bowl during transportation, this can affect not only the parts themselves, but also the appearance of the device.
You need to carefully examine the outside of all the elements of the multicooker to determine the problem. Another reason is overheating, when the multicooker is left on for too long, overheating of its parts occurs and the built-in overheating protection is triggered. In this case, you need to wait until the device cools down, and after a few hours try to turn on the device again.
If the multicooker does not turn on, you need to contact the master. Also, the reasons for automatic shutdown include the case with an overabundance of products, then the devicetries to protect itself from unnecessary processing. If loose ingredients or moisture get into the bowl and take up the space underneath, this can also cause problems.
If the pressure control valve is clogged, just rinse and dry it. The system stops the cooking process if something is burnt in the bowl or additional substances lie outside its space.
Also, when the bowl is completely filled with solids and no water is added, the appliance turns off. These are just some of the reasons why the multicooker does not turn on, but in fact there can be many more.
Timer breakdowns
In modern models of multicookers, special sensors are installed, the task of which is to keep track of the cooking time and control the cooking process. When the mode is started, but the timer does not count down, this indicates a breakdown.
In this case, we can talk about the factory settings of the timer or automatic control errors. Before use, be sure to read the instructions, where there is a section that addresses this issue. In most cases, the timer stops counting due to a loose lid.
The malfunction may manifest itself in the fact that the multicooker has turned off and does not turn on to normal operation. If the lid is well closed, the timer does not activate, then most likely there was a failure in the electronic mechanism or the temperature sensor burned out. After the problem is fixed by the wizards, the device will continue to function normally.
Such failures can occur without a malfunction in the timer. If the lid is closed, there is no damage to the surface of the multicooker, but the timer does not turn on, you just need to remove the plug from the outlet, wait a few minutes and then turn on the device again. It is not recommended to climb inside the device on your own to look at the operation of the mechanism.
Even if the multicooker has turned off and does not turn on again, you should not do something yourself.
The device does not turn on
A popular problem that occurs most often during the initial acquaintance with the multicooker. This may be due to incorrect installation of the bowl, in which case the protection system starts to work, the device cannot turn on.
If we talk about individual models, they can make different beeps, which resemble a timer, but the machine starts beeping in different tones. In this case, the troubleshooting is simple, you need to turn off the product, remove the bowl, see how it needs to be fixed in place, and follow the instructions to complete this step.
Be sure to check if the bowl "sits" firmly in its place. If it is overloaded, you need to remove some of the products so that the device turns on normally. If the multicooker mode does not turn on, then the problem is most likely an insufficient amount of liquid, which is poured into the solid components in the bowl. You need to fix this problem and try to turn on the device again.
Additional reasons
If the voltage in the home network is unstable or low, this may cause a number of problems in the functioning of the appliances. One of the reasons why the multicooker does not turn on and the display does not light up may be clogged contacts due to food outside the bowl getting inside the product. Be sure to protect the contacts, wipe the surface dry and, after fixing the bowl, turn it on again.
If the problem is a faulty chip, you need to call the wizard. If the thermal fuse is blown, you need to contact the service or, if possible, replace it yourself. Another reason, in addition to improper operation, may be clogging of the valve through which excess steam passes. It needs to be removed from time to time, washed from contamination and reinstalled.
When the cooking mode is set incorrectly, the start in the multicooker does not turn on. Everything can be fixed, try to turn on the device again. If the bowl is deformed, which is a rare occurrence, you need to contact the service center or the store where the appliance was bought.
Failure Diagnosis
The product is equipped with several sensors that control and regulate the operation of the multicooker. The main sensor is called a thermistor, mounted in the main button. It is difficult to repair it yourself, and therefore, when repairing, you must contact the master.
The second working sensor is located inside the product cover, in order to get to it, you will need to dismantle the filling with the compound,by disconnecting the sensor, and thus turn on the product again. If the part does not work, then the master is on the right track, and you need to check the wires going to the sensor with a multimeter, since the cause of the problem lies in them.
To improve the efficiency of the multicooker, you need to read the readings from both sensors at once. They may be the key answer to the question why the multicooker does not turn on.
Minor problems
There are also cases when the multicooker does not turn on during the cooking process, because the bowl does not heat up to the desired temperature. Masters advise to make resistance measurements on the transformer. Behind it is a special rectifier, which consists of 4 diodes. The main board is always element down.
When opening the bottom cover, you can visually determine by drops of tin on the surface which of the circuit elements does not work, where a short circuit has occurred. Also, for additional verification, you can double-check the operation of the relay.
Replacing the thermal fuse
This element protects the electrical circuit from a sharp jump in temperature. In case of danger, it breaks this circuit and stops the operation of the entire product in order to avoid overheating. The fuses are easy to make, low cost and easy to replace.
To begin with, they disassemble the product, look for black or orange among the wires, then move the safety tube to get to the main part. Wire cutters need to release it from the chain and insertnew fuse. After that, the connections are clamped with special clips.
Now the equipment is protected from overheating. If the multicooker has stopped turning on, then perhaps the reason lies precisely in the fuse.
Product ICs
Standard devices have two control and power supply circuits. In order to get to the second one, you do not need much work, but the control board is inside the cylinder, and you need to carry out a complete dismantling of the product. Therefore, experts advise first to conduct a visual inspection.
You need to focus on the presence of chips and soot, blackened parts, a specific smell, broken solder seams and swollen capacitors. If this is one of the reasons, then it is necessary to change the control board. If during the repair process you need to add several jumpers, after finishing work, you should definitely check how securely they are fixed.
Tips for users
In the case when the multicooker does not turn on, first of all you need to disconnect it from the mains. After that, visually inspect and check the fixation of the bowl. If everything is fine and there are no visible violations, you need to contact the master. There is always a potential factory defect in the capacity or incorrect loading of the quantity of products.
If the appliance refuses to turn on, you need to look into the issue in detail and check everything from the ingredients tab to the surface outside the bowl.
After that, you can also look at the diagram andworking parts of the machine. If there are burnt contacts or heating elements, then you need to fix it yourself, you can not call the wizard. Also pay attention to the mode for cooking.
Types of multicookers
In today's market you can find a lot of different options and models, ranging from simple to more expensive with additional features. Experts advise novice consumers to use simpler models in order to learn how to use the mechanism correctly. It is also necessary to follow the multicooker modes and check the instructions during operation.
Quick check
If the multicooker does not turn on, the reasons can be quite simple. There may not be enough liquid inside, which is preventing the device from starting. On the inner surface of the bowl there are limiters for weight and parameters. If you collect more food than the device can process, it will turn off the machine.
The third factor that affects the operation of the machine is the power grid. If the voltage is insufficient, malfunctions may occur and the device will turn off. The multicooker does not turn on, what should I do? No need to panic, you need to carefully inspect the device.
Conscious damage
Sometimes the cause of a shutdown may be hidden in improper operation. If the surface outside the bowl is cleaned with metal objects, the bowl is scraped off with a knife, cracks and chips appear on the surface, which then affect the process and work. You can not multicookerleft on for too long as the sensors and operating elements will overheat.
User Tips
In order to avoid problems, you must first read the instructions, correctly fix the bowl inside the mechanism, check the power supply and fix the plug in the outlet, load the food correctly and add the right amount of water, select the desired mode and try to turn on the multicooker.
The device has a number of protective properties, thanks to which it can independently control the process of work. A rare case when a new device requires the intervention of a master or there are factory defects. When the multicooker does not turn on, what should I do? It is necessary to check the voltage and the surface of the device, look at the fixation of the bowl, whether the lid is securely closed. These simple tips will help you avoid problems in the future.
