Multicooker polaris DIY repair

In detail: polaris multicooker do-it-yourself repair from a real master for the site my.housecope.com.

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:

liquids poured into the bowl, through negligence, may spill inside the mechanism;
forgetting that the container is on the table, you can start pouring liquid into the inside of the equipment, thereby drowning the mechanisms or filling them with bulk products.

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.

Remove the metal (plastic) cover and other visible items attached with screws.
Clean the microcircuits by turning the device over and gently shaking it off.
Secure the cover and other top elements.

In the case when the clogged contacts are at the bottom of the device, you must:

unscrew the screws securing the bottom cover;
disconnect the cables connecting the heating and software boards;
remove the heating element by unscrewing the screws;
carefully remove the internal thermometer without damaging the device;
clean chips and boards from bulk products.

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, so for repairs on your own, you will need to remove the device case and use the multimeter's capabilities 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.

One of the main reasons for the failure of the multicooker is the ingress of liquid on the elements of the electrical circuit. The first rule here is the need to follow a certain sequence - first, the products are placed in the pan, after which the pan is placed in the device. If you put the ingredients directly into the multicooker, then it can threaten that the liquid may spill outside the working bowl, on the "insides" of the device. Even in small doses, it is dangerous. As a result, the multicooker will break down, and you need to completely disassemble and clean it. If the inside is already dirty, in no case turn on the device, otherwise the contacts may burn out.

First, remove what you can remove without problems. As a rule, this is a plastic cover at the bottom of the case, fixed with self-tapping screws. After that, we clean the board and contacts from cereals or spilled liquid. The easiest way to shake out the groats is by simply turning the device upside down. Next, unscrew the bottom. The bottom board can be snapped into a box and you will need to remove the box before cleaning it. Disconnect the cable from the bottom board to the software board. Next, we disconnect the heating element for cleaning. In the center you will see the thermometer wires, and if the croup even got there, remove it with the utmost care - it is easily damaged. Upon completion of disassembly, the assembly is carried out in the reverse order. In order to successfully assemble everything later, we advise you to photograph the disassembly process.

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, the ingress of moisture 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 at least once a year with intensive use of the multicooker. By the way, a bowl with a polymer coating does not last forever. So, most likely, you will have to change it. If the pressure valve allows steam to pass through even in the "Closed" position, then only the service center can fix it.

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. Do not overload the multicooker - when boiling, some of the liquid may simply spill out of the pan. The sealing gum in the lid is also needed to prevent moisture from entering the electrical contacts. After washing the lid, do not forget to put it back.

Here is what the hostess, an experienced user of the multicooker, writes: "I accidentally turned on the device without a pot, noticed it only after 40 seconds, and immediately turned off the device." The woman wanted to know what would happen to her Redmond M90 if the pot was not replaced at all?
We can assume that nothing bad will happen. The main button, located directly under the bottom of the pot, will prevent the multicooker from turning on in the absence of dishes. The hostess conducted an experiment: with the lid open (!) And the pot pulled out, she started the program. The heating element became hot within 10 seconds. The bottom line is stunning: there is no protection against incorrect inclusion in the Redmond multicooker.

We did not conduct such an experiment, and we do not recommend it to you either. However, blown thermal fuses are one of the most common causes of failure of a multicooker. This can also be seen from the repair case shown in the video. The foreman checks the fuses first. If it's about them, then you can try to make the repair yourself. You only need a tester to check.
Indeed, most of the multicooker comes for repair with a “does not turn on” malfunction.We insert the plug into the outlet, and there is no reaction to switching on. Cause of malfunction: failure of the thermal fuse. This often happens because the bowl is not fully inserted, and an air gap appears between the bowl and the heating element. If the bowl does not fit snugly against the heating element, the temperature will quickly exceed the maximum fuse level and it will burn out.

However, repairs require certain knowledge, skills and, finally, spare parts. The manufacturer may well fill the terminals with compound (by the way, this speaks more in his favor), the fuses used, depending on the power of the multicooker, are also different.
We found many interesting cases of repair, when it is necessary to disassemble the multicooker and clean the heating element, for example, from jam.

But the next video amazed us with the ingenuity of the Russian master in search of an unexpected replacement for the power supply of the electronic filling of the device. So, if you are not tired of this topic yet, please go to our cinema.

When the blockage occurred in the bottom of the device, where the contacts are located, then the algorithm of actions will be as follows:

disassembly is carried out from below - we unscrew the screws securing the bottom cover;
we disconnect the wires going to the software and heating board;
we unscrew the screws securing the heating elements - after that they should be easily removed;
carefully, so as not to damage, dismantle the internal thermocouple;
we clean all microcircuits, thermal sensors and boards from bulk products.

If you do everything without haste, carefully and carefully, then you can clean the Polaris or Mulinex multicooker yourself without any problems.

One or more thermal fuses are always located in the middle of the product, no matter what manufacturer the multicooker is, for example, from Panasonic. They are covered with cambric, which in individual products are collected in a common clamp, but most often they are not fixed.

Under the bowl in the multicooker there is a special unit, visually similar to a mushroom made of metal, which is supported by a spring from below: various fuses are located around it, you can get to them and fix them only by turning the fasteners of the bottom cover.

When replacing a thermal fuse, only clips are used: they cannot be soldered, because they are very sensitive to any temperature rise. You can check the condition of the fuses using a testerto find out which one burned out.

Another temperature sensor is located in the lid, you can check it without opening the plastic device once again: it is enough to measure its resistance while heating the lid. If there are no changes in resistance, then you will have to disassemble and make unscheduled repairs to the multicooker lid with the replacement of the part.

Each user should know that thermal fuses cannot be repaired, their specific purpose is to burn out when the temperature rises sharply.

We have already explained how to remove the back cover - you need to unscrew the fastening screws, then disconnect the thin wires that connect the control board with the power supply. Next, we disconnect the heating elements and, with extreme care, the thermocouple located in the center - this part is very fragile and is afraid of any mechanical impact.

To clean the board from carbon deposits, it must be disconnected, providing access from both sides. We carefully examine it for the presence of fatty spots, if any, we wipe it with a cotton swab dipped in alcohol. For multi-cookers of different models, the location of the boards may be different.

Microcircuits must be examined very carefully, using a magnifying glass to reveal carbon deposits, irregularities in tracks and solder seams. If you do not understand anything about this, then you should not contribute to the application of defects to such a fragile and important part. The damaged parts are carefully soldered and replaced with new ones, taking into account the coincidence of the marking. After repairing the boards of the Redmond multicooker, if you made it yourself, you need all the tracks varnishto protect them from moisture penetration.

Quite often, the redmond multicooker and steamer has the top lid latches breaking.According to experts, this is one of the most common breakdowns. Some masters claim that it is manufacturer's defectso that users buy new top caps after a certain period of product use.

If a breakdown still occurs, then you should not immediately go to the store and spend money on buying a new cover, especially with such a minor breakdown it is pointless to contact the service center: they simply do not undertake to repair the multicooker, advising to install a new cover. There is an original home repair method, which does not take much time and effort, you only need concentration, patience and the ability to work with superglue. In order to properly troubleshoot, watch this video carefully:

The main reason for multicooker breakdowns is the ingress of liquid or bulk ingredients inside, and this is 100% your fault. Better to put the food in a bowl on the table, add water, and then gently insert it into place. It makes no difference which company the multicooker is: Polaris or Redmond, if food or liquid got inside, and you connected the product to the network, you will need urgent repairs.Carelessness and haste - these are the main reasons for the failure of household appliances. Experts have established two main factors affecting the good condition of the multicooker.

According to the recipe, it is necessary to add milk or other liquid without removing the already heated bowl, since there is a risk of getting them on the electronics due to the user's carelessness.

Many housewives in a hurry forget to insert the bowl and put food inside the product, which inevitably leads to breakage.

Only an attentive and careful attitude to the multicooker, adherence to the rules of its use, can guarantee a long operation of the product and stable functionality.

The correct large carrying handle is hidden behind the case:

The LCD screen works in touch mode, and the control system is more or less clear:

Well, it is still better for the stupid ones to familiarize themselves with the instructions for the multicooker.

Comes with a 5 liter saucepan (called a bowl):

In terms of energy saving (Polaris PMC 0517 AD consumes a little more than 800 watts), a multicooker is comparable to a weak induction cooker. You will not use a lot of electricity (therefore, it is ideal for a summer residence).

The rest of the bells and whistles from the kit:

I must admit that I do not know how to cook (the maximum that I have mastered is heating), but my wife in the country uses every day - she is happy with the multicooker.

Good thing, good value for money, we can say that I recommend this multicooker (so far only positive impressions).

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 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.
