Causes and elimination of errors in multicookers, error codes e01-e05

A crock-pot is a modern kitchen appliance, which in case of malfunctions does not just stop functioning, but can indicate on the control panel a specific reason for the violation of the operating algorithm. Electronics identifies a failure and displays error codes with the letter e from 1 to 5. So, devices of different brands can signal, including the Brand 502 multicooker: “Error e3”. What to do in this case is explained in the material.

Typical faults for most multicooker models

Regardless of the manufacturer's company or the features of a particular model of a kitchen appliance, the causes of error codes e1-e5 on the control panel of the most popular multicookers are very similar. In general, malfunctions in the operation of this household appliance arise due to:

  • moisture inside;
  • ingress of foreign objects and substances;
  • short circuit or breakage of sensors;
  • dirty contacts;
  • pressure sensor triggering;
  • lack of a bowl or its deformation;
  • incorrect position of the multicooker lid;
  • burnout of power and control boards.

Modern electronic devices are able to indicate possible problems in their work using alphanumeric identifiers - error codes

If we consider specific cases, the error e0 indicates the incorrect position of the lid of the device - it is not closed due to improper position of the silicone seal or deformed. The problem may lie in the open circuit of the upper temperature sensor.

Failures e1 and e2 mean either the presence of foreign elements between the bowl and the bottom of the device, or mechanical damage to the temperature sensor in the lower part of the multicooker. They may also indicate unsoldered sensor sockets on the control board below. Error e3 is most often an indicator of moisture penetration between the appliance bowl and the heating element.

IMPORTANT. Proper operation of the pressure cooker, maintaining its cleanliness and safety from mechanical damage is the key to long use of the device without the need for repair.

The most difficult repair will be required when the e4 designation is displayed, which means there are problems with the pressure sensor at the bottom of the device. If the e5 indicator is on, then this is a signal from the automation about problems with overheating of the product or the absence of a bowl inside the multicooker. The problem in this case may also lie in the fact that the steam valves are clogged, the device is near heating appliances or the wiring has burned out.

Error codes in a Polaris cooker

Most of the faults in multicookers from the Polaris brand are associated with a malfunction of the thermal control system or overheating of the device. Each model may have its own codes, but in general, the indicated errors are presented in the table.

E1Temperature sensor short circuit
E2Short circuit of the upper temperature sensor
Open lower temperature sensor
E3Problems with the temperature sensor under the bowl
E4Open upper temperature sensor under the cover

Thermal relay failure is one of the most frequent breakdowns of Polaris multicookers

IMPORTANT. Sometimes the appearance of error codes on the panel can be just a malfunction in the system, and not a serious malfunction. Before diagnosing a breakdown, turn off the multicooker and turn it on after a while.

What error codes can occur in a multivark Brand 502

In the Brand 502 multicooker, most often failures occur with a pressure sensor at the bottom of the device, as well as in the case of poor contact of the device bowl with the heating part.

E0Short circuit or open circuit in the upper sensor circuit
E1Short circuit or open circuit in the upper sensor circuit
E3Deformation of an electric heating element or bowl
Starting the device program when there is no bowl in the device or products in the bowl
Malfunction in the control panel
Third-party elements are caught between the bowl and the heating element.

The most common malfunction of multivarks of the manufacturer Brand 502 is the error code e3, which means malfunctions with the pressure sensor or deformation of the device bowl

You can repair the device yourself only if the reason was: lack of contact between the bowl and the heating element, foreign objects between them or the absence of the bowl itself in the device. In other cases, it will not be possible to repair the multicooker at home, you should contact a service center.

How to understand what kind of malfunction occurred in the Vitek multicooker by the codes on the panel

The manufacturer of multicookers company Vitek in the user manuals for the operation of devices does not indicate either specific trouble codes or the possibility of breakdowns in general.

Vitek multicooker manufacturer does not indicate possible solutions to equipment problems either in the instructions for the appliance or in the outer packaging

Based on the feedback from users who encountered problems in using the device, two frequently occurring errors can be distinguished:

  • E2 - overheating. The device has not cooled down from the previous cooking cycle.
  • E4 - indicates a malfunction of the temperature sensor in the cover. It is connected with an unreliable contact in the connector from the sensor in the cover.

Error E0 on the Mulinex multicooker control panel means that the temperature sensor in the upper part of the device is closed or open

The most frequently occurring codes are collected in a table.

E0Short or open upper sensor
E1Open or short circuit lower temperature sensor
E2Malfunction of the power board
E3Control board is not functioning
E4Temperature sensor short circuit
E5Thermistor break

Repair a multicooker at home: how to open the appliance

When fixing the problem yourself, you need to understand that the device loses the factory warranty - only the owner of the multicooker bears the result or its absence. In the future, free maintenance, replacement of defective or failed components in the service center will be excluded.

If the crock-pot has broken during the warranty period, then it is more rational to entrust its repair to professional craftsmen from the service center: it will come out cheaper and faster

If the warranty period has already expired, for reasons of failure there is no doubt and the owner of the device has elementary technical skills, you can try to fix the device yourself.

The main rule of self-repair of any electrical appliances is safety: you must always remove the power cord from the appliance or from the outlet

IMPORTANT.Before starting any repair of equipment, make sure that it is disconnected from the power supply.

To see the source of the malfunction with your own eyes, you need to open the device. To do this, follow these instructions:

  1. To access the sensors at the top of the device, simply remove the plastic cover.
  2. Three fasteners at the bottom give integrity to the bottom of the multicooker - they need to be unscrewed.
  3. Disconnect the cable connecting the two boards: the software and directly the bottom of the multicooker.
  4. Remove the heating element that is held in place with screws and a mounting plate.
  5. Carefully remove the heaters, an internal thermometer that is designed to monitor the temperature during operation of the device.
  6. Find the damaged contacts and begin to clean them.

When replacing or cleaning the sensors in the upper part of the kitchen appliance, you just need to remove the plastic or metal cover of the product

Replacing sensors is a fairly simple operation, but you must be sure that it is their failure to work that is the true cause of the breakdown. It is likely that the wires of the upper sensor broke on the bend of the lid, they peeled off or there is not enough thermal paste.

One of the causes of the malfunction may be a blown fuse, which has the form of a wire similar to a resistor. The most likely causes of combustion are malfunctions in the power supply and control units, as well as sudden voltage drops in the network. It is necessary to check whether the element is working or defective, using a tool for measuring resistance - a multimeter.

How to fix errors e1, e 2, e3 in kitchen devices yourself

The easiest option is errors e1, e2 on the screen, which mean that food remains are inside the device or the temperature sensor is mechanically damaged. Repair should take place as follows:

  1. Remove the bowl from the multicooker.
  2. Make sure that there are no foreign objects or moisture on the heating element and the bottom of the bowl.
  3. Unscrew the bottom mount - in the very center under the bowl find a tubular thermocouple.
  4. Press the top plate until it clicks on the same side as the adjustment screw.
  5. Using sandpaper, carefully clean the terminals with the contacts closed.
  6. Reinstall the components, assemble the device in its original form.

To check whether an open circuit has occurred inside the device, it is possible on the wire leading from the sensor to the display, using a device for measuring electrical active resistances - an ohmmeter.

Moisture inside the pressure cooker may not get into the bowl when washing or pouring liquid into the bowl, but directly in the device

In case of moisture (error e3):

  1. Remove the multicooker bowl, turn the appliance over.
  2. Unscrew the bottom bracket, ensuring free air circulation.
  3. Allow the appliance to dry naturally or speed up the process with a low-power building hair dryer.

Troubleshooting instructions for e4 and e5 in multicookers

Problems with the pressure sensor (code e4) at the bottom of the device can be solved by passing a narrow strip of plain or sandpaper between the sensor contacts. This must be done carefully so as not to break the resistors completely.

An open circuit or a malfunction in the microprocessor is also possible - this is the most difficult case in which the unit must be checked completely and clearly not at home.

The heating element of the device is fixed through the mounting plate with three bolts

If the control panel gives an error e5 - indicator of overheating of the device, then the repair involves the following steps:

  1. Turn off the device using the "Start" button.
  2. Disconnect the multicooker from the power source.
  3. Open the lid, remove the bowl with the protective gloves.
  4. Leave the appliance and bowl to cool for 20-30 minutes.

What to do when repairing the device is in no case

Attempts to troubleshoot the electronic mechanism are unacceptable in the following cases:

  • the crock-pot ceased to be included and to react to any influence;
  • different error codes are displayed or the display gives unreadable characters;
  • there is a visible damage to the device body or electric cable;
  • the heating element does not fulfill its function;
  • temperature information is missing;
  • it is not possible to achieve the tightness of the lid.

All error codes and their description for a specific model of a particular manufacturer should be indicated in the instructions that are included with the multicooker. If this information is not in the user manual, you can contact the official representatives of the brand or specialists of a certified service center who are required to carry out warranty service of the devices.

You can try to fix the multicooker yourself, but it is better to immediately entrust the repair of this electronic kitchen utensil to a qualified craftsman with experience and a supply of necessary components. Then the updated kitchen assistant will honestly serve for a long time.
