By the way, about the bowls. Bowls Redmond RB-A400, RB-S400 are great for Scarlett SC-411. The first is teflon-coated, the second is twice as expensive, made of stainless steel.
We took the one that is cheaper (pictured above) and for a year and a half no complaints. We cook often.
Most modern housewives know about the benefits and effectiveness of Redmond multicooker firsthand. This multifunctional kitchen fixture has provided thousands of homes with wholesome, nutritious, hot and delicious food. Everyone who has used this device at least once has become convinced of its effectiveness. However, like all electrical appliances, it is susceptible to various breakdowns.First of all, malfunctions of the device are attributed to a factory defect. Nevertheless, it sometimes happens that the device breaks down during operation. It is then that most people think about repairing a multicooker with their own hands. It is possible to perform it at home, but for this you have to take into account several nuances.
In order to protect the Redmond multicooker from breakdowns and not think about how to fix it with your own hands, you must comply with the requirements prescribed in the device manual.
The first step is to highlight the sequence of stacking products before cooking. Remove the food bowl from the Redmond multicooker before placing it. Otherwise:
Most malfunctions occur due to contamination of the contacts of the device. This can result from the ingress of liquids or bulk solids into the interior of the device, such as:
This type of breakdown is the most harmless and it will be easy to repair the multicooker with your own hands. At the same time, it is worth remembering that until the end of the cleaning and assembly process of the structure, the device should in no case be connected to the network.
To clean the device with your own hands, it is important to study and follow the sequence of actions.
Observing the rules of disassembly, cleaning the device will not cause much trouble.
In some cases, Redmond multicooker may stop working, displaying a specific alphanumeric error code. The ability to decipher the code will allow you to understand the cause of the breakdown and start fixing it. Information for decryption is known to manufacturers, as well as craftsmen specializing in the repair of household appliances.
Certain errors displayed on the screen indicate serious malfunctions. Nevertheless, there is a list of codes that ordinary users have explored through trial and error.

Thus, craftsmen managed to find out that the message "e0-e4" displayed on the screen signals faults associated with short circuits, as well as breaks of temperature sensors located above or below. Also, the problem may be related to thermal fuses. Various manufacturers set their own codes, therefore, for repairs on their own, you will need to remove the device case and use the capabilities of the multimeter to detect an open by measuring the level of contact resistance.
Another common reason that a multicooker may need to be repaired is a clogged thermostat responsible for heating. In most cases, it is located at the bottom of the device, next to the power board. To get to and repair the thermostat, you need to remove the bottom of the structure. Before cleaning, the copper contacts must be slightly unclenched, and then wiped with zero emery cloth or thick paper. The reason for such a breakdown may be the accumulation of moisture that has penetrated into the mechanism due to the liquid spilled past the bowl. Condensation is also possible.
A thermal cutout for a multicooker is one of the most important parts of it.It is a small piece of wire that is indistinguishable from a resistor. The conductivity index is 10-15 A, based on the type of element. The highest temperature is 150-170 degrees. Exceeding the permissible limits will lead to a blown fuse and an open circuit, which can be determined using a multimeter.
The most important part of the Redmond multicooker is at the center of the device. Most modern models are equipped with several thermal fuses covered with protective plastic insulation. To detect a blown fuse, it is necessary to dismantle the bottom cover of the device.
After removing the bowl, you can see the button: outwardly, the assembly resembles a steel mushroom, the lower part of which is covered with a spring. The circumferential surface is the heating element of the Redmond multicooker. Thermal fuses are located near the main unit.
In this case, the plastic insulation is visible. Some manufacturers secure them with clamps screwed to a screw, but in most cases, the fuses are simply dangling in the air.
Since the factory fastening of the fuses is carried out by crimping, the use of soldering is strictly prohibited, since a red-hot soldering iron can burn out the heat-sensitive fuse. To determine which element is defective, and whether at least one of them is working, using a multimeter, you should measure the resistance without removing the fuse. After detecting a malfunction, the fuse must be replaced.
Modern multicooker is equipped with two electronic boards:
The main board, responsible for heating, is located at the bottom of the device, while the control board is located in the heart of the device - inside the working cylinder.
A close inspection of the microcircuits reveals several signs of problems:
delamination of tracks;
violation of solder seams;
blackening of resistors;
swelling of capacitors;
formation of carbon deposits.
If one of the items on the list is found, it is worth repairing or replacing parts, restoring the soldering or tracks of the board using a zero skin and tinning the damaged places. Jumpers can be made from burnt-out resistors using their legs. To secure the soldering and tracks, it is recommended to use a varnish that protects the circuit from leaks and oxidation.
Multicooker repair - errors and malfunctions, the multicooker is broken.
Multicooker perfectly complements the interior and functionality of modern kitchens, coping with dishes of any complexity. You no longer need to worry about whether your milk porridge will run away, or whether your patties will burn. But if you want you to need to repair the multicooker as late as possible, or not at all, you need to know the basic rules of its operation, and in no case violate them. Regardless of the brand of your multi, whether it be Redmond, Panasonic, Polaris, Moulinex, Vitesse, Phillips, Scarlet, Smiley, ARS, Cuco, Supra or some other company. Let's talk about this.
The first rule is the need to follow a certain sequence - first, the food is placed in the pan, after which the pan is placed in the device. Not the other way around! If you put the ingredients directly into the multicooker, then this can threaten two dangers. Firstly, the poured milk or water may spill out of the working bowl, onto the “insides” of the device. Even in small doses, it is dangerous. Secondly, you can simply forget that you washed the pan, but forgot to put it in the device, as a result of which you will pour the same milk or pour cereal directly onto the contacts and boards. As a result, the multicooker broke down, and in order to fix it, you need to completely disassemble the device and clean all the contacts. If the inside is already dirty, under no circumstances plug the device into the mains until the end of cleaning, otherwise the contacts may burn out.
How do I clean a dirty device?
E type multicooker malfunctions
Sometimes an error message appears on the screen of the device, in which the letter E appears with an index. Such errors are corrected depending on which index the technician is showing you. For example, the errors of the E1-E3 multicooker are, most likely, moisture getting into the pressure cooker. The fix is followed by removing the bottom and leaving the device alone until it dries completely for several hours. If you don't want to wait, you can use a hairdryer. Correction of malfunction E4 - cleaning the pressure sensor with a centimeter strip of office paper. Alternatively, you can pass fine sandpaper between the sensor contacts several times. The multicooker error codes are described in more detail in the manual. If the error persists, you will have to contact the service center.
Sometimes the multicooker gives an error, and sometimes a malfunction can be noticed without any information on the display. For example, if you notice steam escaping from under the lid, this may indicate a problem with the O-ring. It is either worn out or outside of the specified seat. If reinstalling the ring did not help, then you will have to completely replace it. This procedure is recommended for at least once a year. If the overpressure valve allows steam to pass through even in the “Closed” position, this can only be corrected by service personnel.
Security measures
Remember that the outer bottom of the hob must be clean and dry. Moisture must not come into contact with the heating element or the protective cover. If you are cooking foods with a high liquid content, never open the pressure valve immediately after cooking. This can cause burns. If you want your pressure cooker to cool down faster, place a damp towel on top of it. The dropped internal pressure will allow the lid to open without difficulty.

It's great when the cooking process is mechanized, then the creation of culinary masterpieces brings sheer pleasure. Alas, not every manufacturer puts in detailed instructions for maintenance. Experts in the field of home appliance repair will offer several ways to disassemble a multicooker of different models. With these tips, it will be great to save your family budget.
Kitchen assistant from the "Moulinex" company
In most cases, it will not be difficult to disassemble the multicooker, because they are assembled according to approximately the same scheme. For a home craftsman who at least once faced the repair of electrical appliances, where the basis is a heating element, the principle of the device will be clear. Below are the main external parts of the enclosure:
Sealed lid with elastic band, on top of which there is a removable steam valve.
A cooking bowl (in older models it is built into the body, which is not very convenient).
Metallized case, with plastic elements (the appearance and finishing materials completely depend on the cost of the device: there are completely iron models in the flagship models).
Button that opens the lid.
Base (bottom).
Inside, under the bowl, there is a heating element disc (TEN).
Soft buttons, control panel screen (sometimes absent, in budget lines).
Handle for easy carrying. It can be located on top or on the body.
The device and equipment of the multicooker Polaris, middle class
The figure shows which wires are at the bottom of the multicooker. Power is supplied via red wires. A switch (which puts the device into operation) and a thermal fuse (protects against overheating) are installed in series. The voltage from the thermal fuse is supplied to one terminal of the heating element, to the power supply board. The white wire is directly connected to the power supply.Through it, voltage is applied to the second output of the heating element, closes the relay contacts.
Wires that supply voltage and ensure operation
Under the heating element there is a power supply unit with standard wiring. He is the most loaded part of the multicooker. Its tasks include converting the current into 220V to direct current 5V and 12V (the first saturates the control unit with power, and the second - the switching circuit, activates the relay). The home network supplies power to the three-pin connector located at the bottom. The yellow-green wire stands out: this is the ground.
A schematic diagram of the internal device of the Redmond RMC-M23 multicooker
Often, manufacturers mount a universal board in the device for the entire model line. Naturally, the technological nuances are kept secret, because firms do not expect to introduce self-taught masters into household appliances. When looking at the photo, an isolated metal round disc catches the eye. This is a battery that, when disconnected from the mains, saves the preset cooking programs in memory.
The figure shows the battery below (yellow)
Temperature sensors are located in the lid and bottom of the product - therefore, you need to disassemble the multicooker with extreme caution so as not to disturb these thin wiring. One wire is connected to the touch screen. A lot depends on these details - they are the “brain” of the device. Damage to the temperature sensors can lead to malfunctioning of programs and cooking modes. Moreover, the kitchen assistant may not turn on, because the required set of heat indicators will not occur.
The device is disconnected from the network, waiting for complete cooling.
The lid is wiped off grease with a soft cloth.
If the fat is not rubbed off, use mild dish detergents, without abrasives.
Wipe dry the lid.
The cover of the appliance is opened.
In the area of the lid, two plastic clips are found. They need to be pressed and pressed towards the center.
The upper sector is pulled towards itself, and then sharply downward.
All internal parts are thoroughly washed from food debris.
To put the part in place, do the opposite. If everything is in place correctly, the clips will make a click when they are seated correctly.
If the product breaks down and you need to see the internal details, and the master does not know how to carefully disassemble the multicooker, then:
First of all, wipe all soiled parts of the product with a rag.
The electrical appliance is turned over with the lid down.
The bottom cover holds the screw, unscrew it. Dismantle the bottom.
All removable wires going to the board are disconnected.
Unscrew the screws holding the heating element.
They remove the thermocouple, all the microcircuits.
Unscrew the screw holding the top cover (when the model does not provide for removal). Then, squeeze the cover with a screwdriver, remove the temperature sensors.
Remove the plastic snap rings (if present around the edges of the metal case).
The inner walls are removed from the outer ones.
When considering the Redmond model range, you can establish: the manufacturer takes care of the appearance of household appliances, reliably masks all the screws and bolts. If we take the multicooker of this company as an example of the middle class, then you can find that screws - trompe l'oeil are placed on the body for decoration. They only play an aesthetic role. The main ones are securely hidden under the plastic.
On some models (Mirta, Polaris, Redmond, Vitek, etc.), screws holding the upper part with a triangular hole. The most common mistake newbies make in repairs is to arm themselves with a cross, apply force, press on the hull.
From mechanical stress, dents are formed, which worsen the external condition of the device. Therefore, it is wiser to use in this case a triangular socket screwdriver, the length of which is from 100 to 120 mm.
The flagship device is manufactured by Moulinex. The build quality is solid. The main advantage is the ease of removal of the inner cover.The entire removable structure is held by a silicone insert, which, thanks to its elasticity, tightly holds the parts. This design is more aesthetically pleasing than external screws.
Cutting edge model from Moulinex
In the budget-class multicooker Delfa, Polaris, Rotex, Scarlet, Redmond, the button that closes the lid often breaks. Masters attribute this feature to birth defects. It happens that the button does not lead due to improper use, but due to exposure to high temperatures. If the device is under warranty, then it is better to contact the service. To cope with this nuisance, you will have to disassemble the case and break the seals.
When closing the lid, the hostess must first hold down the button, and after covering it completely, release it. Less stress on the part reduces the chance of breakage.
Broken open button
Two repair options that do not require complete disassembly:
The surface is degreased, glue is applied and magnets are applied so that after closing the lid they meet. You can take one large one, but it is better to take four small ones to connect them in pairs.
In the dropped button, two small holes are made for the stem. The same is done in the case, at the place where the latch is attached. Then, thread the stem through the removable part. Gently insert the structure into the body.
Parts are purchased in the store, the use of self-made inventions is not desirable. Using these can lead to fire! Moreover, the price does not bite on elements that can be replaced at home. If adequate operation of the device is disrupted, system errors appear on the screen. Reading them, it will become roughly clear which part needs repair and replacement.
E1, E2 - there have been changes in the operation of the power supply unit, the heating element, the lid is not tightly closed.
E3, E4, E5 - the device has overheated and the protective function has worked, the temperature sensor has broken. In some models, with this breakdown, a picture is not displayed on the screen. If we are talking about the "Redmond" company, then a damaged wire that goes through the body and the cover can become a possible ailment. We disassemble, remove the plastic at this gap (snap off with a screwdriver) and measure the resistance. The next step is to disassemble the bottom and ring the clamps under the heating element.
All devices are equipped with fuses that will blow in any situation that, in the opinion of the developers, could lead to a hazard. For example, if the hostess turns on the device, while forgetting to install the bowl inside.
When purchasing a multicooker, be sure to familiarize yourself with its characteristics: the presence of a removable cover, whether the rubber bands must be replaced at home, how reliable the latch is. To prolong the service life of the appliance, observe hygiene inside and out, avoid the ingress of cereals and food residues, operate as intended and follow the instructions.
Lid, with elastic fastening
In order to accurately disassemble into parts, it is important to know how the multicooker works. It seems that this ordinary-looking saucepan does not have a complex scheme, but it is not. There is a fragile electrical part inside. It can be easily damaged if it is roughly applied to the case.
A simple multicooker is under repair SCARLETT SC-411 - with error indication E4 ... For repair, we open the multicooker (the bottom is removed). The control unit is fixed in a small box at the bottom of the multicooker, on two stands. Among the connectors we find the one that comes from the top cover. We remove the connector plug and measure the resistance. The ohmmeter shows resistance close to zero. That is, the sensor is short-circuited. Everything becomes clear when we open the top cover, inside which this sensor is fixed. The sensor itself MF58-104 inserted inside a silicone tube, and the wires are tightly pressed together with it to the metal top cover using aluminum self-adhesive tape. From the high temperature, the insulation melted and the wires shorted. This is where the E4 error comes from.
But it was only necessary to disconnect the wires, and peel them off from the metal top cover, as an error already popped up E3 ... A second measurement on the disconnected plug of the connector at the control unit now showed an open circuit.
That is, the temperature sensor is now torn off inside. The picture is clear - during the cooking process at the maximum temperature (frying, stewing meat in oil), the upper temperature sensor failed (this is an error E4), and when they tried to remove it, it broke off (this is an error E3).
I must say that in the range of used MF58 sensors (datasheet for it here) there is a very wide variety of resistances - 10 kΩ, 20 kΩ, 50 kΩ, 100 kΩ, 500 kΩ. Most often, the MF58-104 (100 kOhm) is installed. Replacing this sensor completely restored the operation of the multicooker.
It makes no sense to talk about how useful and effective the multicooker is, how it made the life of housewives easier, and also provided thousands of families with always tasty, hot and healthy food. Everyone is already convinced of this.
However, sometimes such a useful and effective device suddenly stops working. Of course, the first thought is a factory defect. And the question arises, is it possible to repair the device with your own hands? Of course yes, but some caveats need to be made.
In particular, we are talking about the correct sequence of stacking products - it is they who must first be put into the bowl, and only then put the bowl itself into the multicooker and in no case the other way around! Remember this! Since the reverse sequence of actions is fraught with the following troubles:
if, in addition to solid products, it is necessary to pour in any liquid, then there is a high probability that it will simply spill out due to carelessness and get inside the delicate mechanism;
the second danger is more serious - it is likely that someday there will come a moment when you just forget that the bowl is washed and is on the table, but out of habit you will start pouring liquid into the open “womb” of kitchen appliances, completely drowning the microcircuits in water or milk ...
Most often, it is contaminated contacts that become the cause of breakdown, which is caused by liquid or bulk products that have got inside the device:
In this case, do-it-yourself repairs are not difficult. Fortunately, there are a great many such step-by-step videos on the Internet. The main thing is to adhere to a certain rule - do not plug the device into the network until the cleaning process is completed and the whole structure is not assembled again.
Naturally, this method should be used only if you are sure that all the problems in the operation of the multicooker are connected precisely with contaminated contacts or have personally seen how foreign objects got inside the device. Otherwise, you shouldn't do the cleaning yourself.
If the warranty period has not yet expired, then also do not take up a screwdriver. It is better to take the multicooker to the service and let experienced craftsmen restore its viability.
In the event that you nevertheless decide that you can do the repair of the multicooker with your own hands, carefully study the list of actions below and strictly follow it.
First, you must remove the elements that are in sight and are not held by anything other than screws. This is a plastic or metal cover.
Removing the cover reveals the microcircuits.
To get rid of cereals or other loose products, simply turn the kitchen appliance over and shake it gently.
The next step is to unscrew the screws on the bottom cover. There are usually three of them. In addition, you need to do the following:
disconnect the cable that connects the lower board of the multicooker to the software board;
remove the heating element, secured by a mounting plate and three (in most cases) screws;
an internal thermometer is located in the center of the indoor unit, allowing the mechanism to control the temperature during cooking. It must be removed with extreme caution, since the device is very fragile.
Such a detailed analysis of the multicooker will allow you to remove all cereal residues inside the device.
It is recommended to carry out such prophylaxis regularly. On average, once a month if you cook every day or every other day.
When disassembling a household appliance, we recommend that you not only lay out all the parts sequentially, which will simplify the assembly process, but also take pictures of each stage. Then, during assembly, you will not get confused and you can put everything in its place.
One of the most common errors that appear with all household appliances is a malfunction displayed on the display of the device with the letter E.
The multicooker is no exception. She can also quite often signal her owner or hostess about any problems by displaying the E index on the monitor.For example, the E1, E2, E3 indices signal that moisture has entered the device, it is necessary to turn off the device and leave it alone for a few hours, allowing the moisture to dry.
Other options for errors marked with the letter E are described in detail in the instructions for the technique, where there are options for troubleshooting. However, if you did everything as it is written in the instructions, and the household kitchen appliance does not want to work again without removing the error message from the screen, you should not experiment, trying to identify the cause yourself. It is better to immediately contact the service center, where they will "cure" your multicooker, returning it to its ability to cook.

Sometimes you can identify the problem yourself, without a message from the internal computer installed in the household appliance. For example, when cooking food, no steam should come out from under the lid. If it stands out, and even in an increased amount, then you should pay attention to the sealing rubber ring. Most likely, it has worn out. If you cook quite often, then there is nothing surprising in this. Replacing the ring is not difficult, the main thing is to find the one that matches your model. This procedure should be performed on average once a year.

So, as you can see, small repairs to modern household kitchen appliances can be easily done by yourself. However, such a smart machine as a multicooker requires careful attitude to itself and if you are not sure what caused the problem or do not know how to handle such equipment at all, then you should not undertake repairs yourself, so as not to aggravate the problem. It is better to immediately contact the service center for help, especially if the multicooker is still under warranty or free service.
