The multifunctional capabilities, speed and efficiency of cooking in a multicooker are known to many housewives. That is why this household appliance is in high demand among consumers. But, like any electronic device, such a device can break down during operation, for example, the cooking mode does not start. In this case, the error E4 starts blinking on the display. In a slow cooker, all problems associated with internal content and the electronic part are indicated by the letter E.
Common Error Codes
When you turn on the device in the network and try to start the program, an error may light up. The most common are E1, E2 or E3. In this case, it can be assumed that water has entered the unit. Automation built into the product warns the hostess that it is necessary to disconnect the device from the mains in order to protect individual parts from overheating. Any error is always described in the attached instructions, the document also provides detailed instructions for a possible correction of the situation.
However, in the annotation for different models, one can find somewhat different interpretations of faults:
- If the E1 symbol lights up, it is possible that not only moisture became the cause of the breakdown. If the heating element burns out, this signal may also flash.
- When a sensor is shorted, which is located inside the cover of the device, the E2 signal lights up.
- Signal E2 may also appear in the event of a broken connecting wire. To check the assumption, it is necessary to use an ohmmeter or multimeter for the presence of electric current.
- If the product gives an E3 error, then there are two possible solutions. You must check the tightness of the lid or dry the inside of the crock-pot located under the bowl.
Slow cooker "Redmond": error E4
The listed error codes apply to any multicooker and mean roughly the same thing. If the E4 signal blinks, then the model of the device must be taken into account.
Consider the Redmond slow cooker. Error E4 means a problem with the pressure sensor. Most likely, he was clogged. However, a malfunction in the operation of the electronic board may also be the cause of the breakdown. The signal does not provide accurate information, so you will have to check all the alleged causes. It is possible that the automation worked and the device simply turned off so that the motor does not overheat.
In any case, if an error code is detected, the product must be carefully inspected for malfunction. If there is insufficient experience or no reason is found, it is recommended to contact a service center.
Kitchen Pressure Cooker Mistakes
A multicooker-pressure cooker can also generate an E4 error. Typically, the problem of such devices is associated with a violation of the function of thermal control or banal overheating. If you disassemble the cover, you can find out that the thermal relay is out of order. In this case, it must be replaced.
But it is worth remembering that sometimes such an error does not mean a serious breakdown, but only signals a malfunction in the electronic system of the product. Therefore, before diagnostics, it is recommended to disconnect the equipment from the network and turn it on again after a few minutes.
Cracking multicooker "Vitek"
The problem of identifying possible breakdowns may arise with the owners of Vitek equipment. The manufacturer does not indicate error codes in the annotation, nor how to eliminate them. However, you can safely focus on the feedback from users who are faced with this situation. Based on their experience, it will be possible to identify the most common breakdowns in the Vitek multicooker
- Error E4. It usually indicates that the temperature sensor, which is located in the lid, has failed. It will have to be replaced. However, simply unreliable fastening is possible.
- E2. Signal during banal overheating. If the hostess launches a new program, and the device has not cooled down yet, then automation does not allow this. The appliance needs some time to cool.
Of course, neither in the instructions, nor on the packaging there are clear indications of possible breakdowns and ways to eliminate them. But, following the feedback from other users, you can identify some minor problems and deal with them yourself.
Problems with the Philips
They are distinguished by excellent quality and impeccable work of the Philips cooker. Error E4, however, can also occur in these devices. As service center employees suggest, the signal indicates that a wire break has occurred that goes from the main unit to the cover. It consists of two parts, inside the inner layer there are many wires, and on the outside there is a mass that is supplied to the housing.
When the hostess often uses the appliance, opens and closes the lid, the wires can bend and burst. To eliminate the breakdown, it is necessary to untwist the insulating wire and find an open.
If the crock-pot generates an E4 error, but the wires are intact, it is recommended to disconnect the device from the network and allow it to cool. After that, the operation sensors must enter normal operation. If this does not happen, then you should contact a specialized center for diagnosis and repair.
The multicooker "Scarlet" does not work
Quite popular with buyers is the Scarlet crock-pot. Error E4 may occur in this device. The cause is also most likely a wire break coming from the main unit to the cover.
If the multicooker has an E4 error, how to fix the situation worries all users. To do this, remove the bottom of the device. The main power supply is always placed in a small box, which is located on the bottom of the device. Then it’s important to find the connector that connects to the cover. Next, you need to measure the resistance with a multimeter, having previously removed the connector. If the device shows values close to zero, then the sensor is closed. Next, you need to remove the top cover and find this sensor. The manufacturer always hides it in a tube of silicone, and wires are tightly pressed to it with a self-adhesive aluminum tape. It is this insulation that usually melts, and the wires close. Hence the error E4 in the Scarlet multicooker.
Sometimes a different problem arises. If you disconnect the wires, peel them off the metal part of the cover, another error pops up - E3. Metering with a multimeter again shows a break. This suggests that when cooking foods at high temperatures, the temperature sensor failed, which indicates the signal E4. If you try to remove it, then the wires break off, and then the E3 signal appears. To restore normal operation of the device, it is necessary to replace this sensor.
Malfunctioning multicooker "Smile"
The Smile crock-pot E4 error can give out for various reasons. If you refer to the instructions, you can distinguish the following:
- open circuit in the temperature sensor circuit;
- banal overheating.
- The temperature sensor is clogged.
In connection with the cause, the methods for eliminating the problem differ. Sometimes to restore the normal operation of the device will help disconnect it for some time from the network. It is also worth checking whether water enters the product from the work surface or bowl.
If, at first glance, everything is in order, it is necessary to turn the device over, unscrew the screws and remove the bottom. Next, you should find the copper contacts that are located in the thermostat. They should be unclenched and sandpaper laid between them.
Multicooker-pressure cooker ARC and its breakdowns
An assistant in the kitchen often becomes an ARC multicooker. Error E4 means that the contact in the pressure sensor has disappeared. In order for the assistant to work again, you must perform the following steps:
- Open the bottom of the appliance.
- Tighten the sensor plate until it clicks.
- The contact should appear after several such clicks.
However, such a solution to the problem may be temporary. To prevent a breakdown in the near future, it is necessary to remove the sensor completely and use sandpaper to clean the contacts. Some craftsmen can do this even without removing the part from its place.
Error E4 in the multicooker can also indicate the ingress of condensate into the relay contacts. To fix the problem, disconnect the power cord from the network. Next, the plastic bottom is removed to detect the relay. It is located near the electronic board. There are copper contacts, which should be carefully unclenched and paper inserted between them. A few movements to the sides should correct the situation.
General error correction rules
A technically sophisticated household appliance is a multicooker. With an E4 error, what should I do? Typically, the device indicates overheating. This can happen when a user in a hurry forgot to put a bowl of food inside. If the bowl is in place, then the following series of actions must be carried out:
- Turn off the device by pressing the appropriate button and unplugging the power cord from the outlet.
- To reduce the temperature inside, open the cover.
- We wait at least 20 minutes until the product has completely cooled.
- Only then can the bottom of the appliance be removed.
If the E4 error blinks, then skills in working with power tools and sandpaper will come in handy. It will usually be necessary to clean the sensor contacts before measuring their resistance. If, after the manipulation, the multicooker does not turn on or lack the necessary skills, you should contact service centers.
Competent repair
When undertaking repairs yourself, you must remember that the factory warranty disappears. Only the consumer will be responsible for the final result. The service center will exclude:
- free repair;
- warranty service;
- replacement of failed parts.
Therefore, if any error codes appear on the device and simply disconnecting from the network does not help to correct the situation, it will be more rational to contact a service center.
However, if the technique is no longer under warranty, the user has certain knowledge and skills, you can try to eliminate the defect that has arisen. In this case, it is important to always comply with safety principles and disconnect the multicooker from the network.
How to open a multicooker
If the technique gives an E4 error, then you probably have to open it. To do this, you must adhere to the following recommendations:
- To access the sensor, just remove the top plastic cover.
- The integrity of the bottom of the home appliance attach fasteners. Usually there are three of them, unscrewed with a screwdriver.
- Next, you need to unfasten the cable that connects the lower part of the multicooker with a software sensor.
- The heating element is held by a mounting plate and screws. It must be removed.
- Next, an internal thermometer is removed, which controls the temperature during cooking and heating tena.
- After that, it is worth finding the damaged contacts. Their cleaning is usually done with sandpaper.
Cardinal solution to the problem
Sometimes a simple sweep will not help in solving the problem. If the crock-pot does not work after manipulation, it may be necessary to completely replace the sensors. However, before you remove them, you should make sure that the action is appropriate. It often happens that the wires that pass along the fold of the lid simply break. Therefore, you must first check the resistance with a multimeter.
Also, a blown fuse can serve as the cause of a breakdown and the occurrence of an E4 error . It looks like a resistor and usually looks like a simple wire. Common causes of combustion are:
- a sharp voltage drop in the outlet;
- malfunction of the control unit or power supply.
In this case, a multimeter is also useful, which will help to measure the resistance in the network.
How to prevent a problem
So that the multicooker does not produce any errors, it is important to operate it correctly. To do this, a number of rules should be followed:
- It is necessary to wash the bowl after each cooking and wipe it thoroughly.
- The valve, which is located on the cover, is important to regularly rinse and carefully descale.
- It is worth tightly closing the lid so as not to provoke the technique to issue an error.
- The device should be installed on a firm and level surface, without any traces of water.
- It is necessary to connect the device to sockets with grounding and the corresponding voltage.
If any error occurs, you must immediately disconnect the device from the power supply.
conclusions
Usually, all error codes of a particular multicooker model and methods for their elimination are described in the attached instructions. If there is no such information, you can contact the service center for help or heed the feedback of other users.
It is better to entrust the repair to a professional, especially if the equipment is under warranty. However, first of all, it is necessary to verify the correctness of the collection of equipment, the absence of excess moisture, the presence of a bowl inside. If, after disconnecting from the network and reconnecting, the problem remains, then if you have basic knowledge, you can repair it at home.
