Why does the multicooker not work

Various household appliances are becoming indispensable helpers of modern housewives in the kitchen: electric meat grinders, toasters, bread makers, microwaves and multi-cookers. All mechanisms can break - what to do if the multicooker does not turn on?

Premature shutdown

When asked by the users why the multicooker shuts down ahead of time, experts give only one answer - incorrect use of the product, resulting in excessive loading of products, or an incorrect cooking mode was set with incorrect temperature.

These household appliances are distinguished by the presence of intelligent processor, which monitors the exact execution of the cooking mode, but the system is unable to recognize whether you have laid the products correctly.It can react to an insufficient amount of liquid, as a result of which the mass burns against the walls of the bowl.

When the bowl is very hot, the temperature sensor is triggered, the heating elements stop heating, the cooking process stops, and the product gives an error code. Disconnection can occur for several reasons:

• factory defect, which did not manifest itself during the check before purchase - most likely it is a temperature sensor, you must carry the product to a service center;
• mechanical damage to the bowl during transportation - carefully inspect everything when buying, because the device may be switched off due to an external defect;
• each mode has its own temperature - when its upper limits are exceeded, an automatic shutdown occurs, since the built-in overheating protection is triggered;
• strictly measure the amount of ingredients using a measuring glass, the machine can turn off automatically when there is a surplus of products;
• remove the bowl and inspect the space under it - maybe loose ingredients or moisture got there;
• pressure regulating valve clogged - flush it;
• burns the contents in the bowl - the system stops the cooking process;
• the bowl is filled with solid foods, and no water is added.

Users at any refusal immediately blame the manufacturer, but in most cases the breakdown is due to your fault: due to carelessness or hasty loading, many hostesses do not close the lid tightly. Therefore, you should not immediately go to the service center, it is necessary to analyze the situation, try cooking the simplest dish - it is possible that the reason for the refusal of the multicooker is hidden in the wrong handling of it.

Timer does not turn on

In Multicookers Redmond set timers in the electronic control system, the task of which is to keep track of the cooking time of a programmed dish. Sometimes the mode starts, but the timer does not count down or hangs after the start of counting.

Experts assure that this is an automatic control device error or the whole thing factory timer setting. Before the first launch of the product, the user should carefully read the instructions, where there is a section dedicated to this issue. Quite often, the timer cannot start counting due to loosely closed lid devices: the timer starts working after a certain temperature, which the user sets, but when the lid is not closed until it clicks, the heat evaporates through the gap, respectively, the timer will be inactive.

If the lid is tightly closed and the timer is not activated, then a electronic circuit failure or burned out the temperature sensor. After eliminating the causes, the multicooker will again function normally: the timer will start on time and will squeak at the end of cooking.

When the timer suddenly stops counting after a short-term use of the multicooker, you should call the master, because the product is under warranty, and it is not recommended to climb inside to diagnose the equipment.

Product not included

This problem can occur during the initial acquaintance with the slow cooker. It happens that the bowl was installed incorrectly: in this case, the protection system is triggered, the device is not turned on, for some models, the beep sounds at different tonalities. It is quite simple to solve the problem: turn off the product, remove the cup and put it back in place, while checking,whether it sits firmly in its place. It is possible that you just overloaded it, remove some products and try again to turn on the slow cooker.

In addition to improper operation, there may be other reasons:

• low voltage in the home network or its temporary absence - is eliminated simply by checking with a special device;
• contacts are clogged due to the ingress of products inside the product - we clean the contacts;
• microcircuit malfunction - if you understand them and the product is no longer under warranty, you can eliminate the cause of the trip yourself, if not, then it is better to call the master;
• the fuse blown out - what to do, we will tell a little later;
• the valve is clogged, through which excess steam is vented - remove it, wash it and put it in place;
• cooking mode is incorrectly set - the steamer will not turn on until everything is fixed;
• bowl deformation - a very rare reason for the failure of technology, but even such a reliable product as Moulinex can refuse according to a factory defect.

Fault Diagnosis

Before troubleshooting these home appliances, the user needs to knowthat all the main programs of home helpers (multicookers and steam boilers) are considered to be commercial secrets of each manufacturer and are not subject to publicity. Why the multicooker does not work - not a single specialist from the service center will answer this question at once, because all the work of the household appliance is based on the precise interaction of the two sensors. Some masters believe that inside the electronic board the developers laid the memory of the nominal temperature, the duration of the operations, as well as the specified programs. Based on this data, the heating elements are also being programmed in the Redmond multicooker.

Sensors are installed in the product.

1. Thermistor inserted to the main product button. It is very difficult to dismantle it, because manufacturers firms do everything to make it difficult to repair themselves, considering it to be the prerogative of special service centers. It is the Redmond company that fills all the terminals with a compound - a special insulating material, making disassembly impossible.
2. A second working sensor is inserted. inside the product cover - To get to it, you will have to dismantle it by pouring it with a compound, disconnecting the sensor, try to turn on the product.If it doesn't work, then you're on the right track. For 100% of the result, call the wires to the sensor using a multimeter.

For effective work of the multicooker, it is necessary to read the readings from both sensors at once: they transmit a signal through the wires to a special terminal of the control board, which is located under the panel with the buttons. When the slow cooker does not work when turned on, the culprit may be Power Supply - you can check this by turning on the product in the network. If at least one of the indicators is illuminated from the inside, then everything is fine. In other cases, you will have to contact specialists.

There are cases that the product is not included in the cooking process - the bowl can not reach the required temperature. Try to make measurements transformer resistance. Behind it is a rectifier consisting of 4 diodes. The main board is located all the elements down, so if the current increases, the solder will melt and flow down to the bottom of the product. When opening the bottom cover, it can be determined visually by drops of tin - this means that a short circuit occurred inside, the heating elements were turned off.

Sometimes worth check the operation of the relay. Connect the product to the network, turn on any program. If you hear a characteristic click, the relay works, otherwise you need to make a phased replacement: first, the relay, and then the control board.

Thermal cut-outs and replacement

They look like a resistor, but in reality they are just a cylindrical piece of wire. Their main task is to protect the entire electrical circuit from a sharp jump in temperature. The response temperature is 170⁰C, the current strength is 10–15 A. In case of danger, the thermal fuse breaks the electrical circuit and stops the operation of the entire product.

Important! Do not try to save a homemade fuse for the sake of economy - this is the right way to a fire.

The fuses are easy to manufacture, they have a low price, in addition, factory copies have fixed characteristics, they have been specially tested and reliably protect the multicooker from overheating. Factory thermal fuses can heat up only up to a certain temperature, and then burn out, opening the entire circuit.

In order for the multicooker to work as before, it is necessary to replace the blown fuse with a new one; to do this, disassemble the product.We look for black or orange among the wires, move the cambric - a PVC safety tube, and there is a thermal fuse under it. With pliers we bite it out of the chain and insert a new device, the connections are clamped using special clips and pliers. Now household appliances are reliably protected from overheating by a fuse, which is always capable of stopping the supply of voltage during a temperature jump.

Product microchips

All Redmond models have two main electronic boards:

• management;
• Power Supply.

To get to the second is not a big deal, but the control board is inside the cylindrical surface, and it will be necessary to make a complete disassembly of the product. After removal of the boards, we perform a visual inspection to identify problems:

• chips and soot;
• blackened details;
• violation of tracks and solder joints;
• swollen capacitors.

If you know how to handle a soldering iron, if you know what tinning and restoration of soldering are, then safely proceed to the elimination of detected defects. It is possible that in the process of repair will have to add a few jumpers. After the repair is necessary varnish everything, to protect against accidental exposure to moisture and oxygen environment, to reduce the oxidation process.

Tips for users

In any brand of multicooker, various faults may appear during the operation, but this does not mean that the equipment is unreliable. There are specific reasons for cooked food in a bowl to burn slightly:

• factory waste capacity;
• wrong load - did not add the required amount of water.

In the event of any failure of equipment or attempts to shut down from the cooking process, it is necessary to understand carefully - first check everything step by step starting with the bookmark of ingredients and consult with a detailed description of this process in the instructions. Finding out burnt contact for a sensor or a heating element, there is no need to call the master - this operation is very simple and can be done by any user, even exclusively with a liberal education.

According to experts, the main failures of reliable household appliances occur the fault of the user - your negligence or inattention. Remember that if the device does not turn on, does not turn off or does not start the set cooking mode, then immediately disconnect the multicooker from the network.

All models can diagnose problems, display an error code on the display - a list of their decryption is in the description. Read it carefully before you repair yourself.
