They cleaned the apartment and decided to do a grand wash. They collected dirty laundry and plunged inside your assistant indispensable in everyday life. Installed the necessary program and launched it. And as a result, instead of adequately performing the selected mode, your machine gives you this:
- I started to execute the mode you selected, perfectly blocked the porthole, and “voila” displayed the Uc breakdown on the screen;
- I advanced in my work, even pumped water, and after highlighted the problem Uc;
- She began to work adequately, and as soon as the time came for heating the water, she stopped and displayed a breakdown on her display;
- It perfectly fulfills the installed program, and as soon as it was time to spin and set speed, it stopped and highlighted a Uc breakdown.
Please note that such a malfunction manifests itself in any mode without periodicity and regularity.
Fault value
The combination of characters Uс, 9С, 9Е1, 9Е2, which is displayed on the displays of Samsung washing machines, notifies you of problems with the power supply. With constant voltage surges (voltage drops in the network), the sensor-controller notifies the control unit, so that with such a power supply the machine will not be able to work adequately. Very often, washing machines that are produced after 2013 block the operation even in the presence of power surges. When it is lower or higher than normal, the abbreviation of Uc malfunction is displayed on the device monitor.
In order for the abbreviation Uc to be displayed on the unit’s screen, the oscillation amplitude must be very large and the differential period (presence of a very high voltage) must be equal to a minute or more, then such a jump will cause a breakdown. After that, the machine will stop and notify you of problems in the power supply.
It should be noted! The combination of Uc characters, which is displayed on the device’s display, notifies that a control sensor has been activated that responds to changes in the power supply network. Such a lock is necessary in order to protect all electronic elements (boards) from damage. The power supply is pre-activated, then the capacitors, and then after all the boards, contact connections, etc.
Malfunction Uc notifies you of problems in the mains, and the control blocking and emergency stop of the unit are immediately triggered.
Malfunction Uc, 9C, 9E1, 9E2, how to fix it without involving professional help
- Power outages. If the jump occurred once, and then the voltage becomes normative (210-220V), then the fault will be eliminated itself. You just need to wait and the machine itself after the suspension of the programs will begin to work in normal mode.
- Lack of stable voltage in the mains. Such a malfunction is displayed provided that in your apartment (house) there are constantly voltage surges in the network. Or the power supply that is supplied from the transformer is constantly below the nominal. As a result of the presence of low voltage, your machine will not perform the selected modes, because for adequate execution of the programs you need certain indicators of power supply, i.e. it should be around 220 V. If the network is overloaded in the morning or evening, when there is a very large load on the network, then it is better not to erase during these periods of time. A special voltage control sensor will block the operation of your device. To avoid such a problem, you need to use a voltage stabilizer.
- Incorrect operation of the voltage monitoring sensor in the network. If a software malfunction occurs and the sensor does not work properly. Therefore, the controller cannot determine the current voltage in the network, therefore, due to the transfer of false information to the control unit, the device is blocked from working. For elimination of such malfunction it is necessary to execute forced reboot. Disconnect the device from the power supply for plus or minus 15 minutes. Restart the machine. After resetting current programs, it should start to work adequately.
- Problems in the supply of electricity directly to the house or apartment. When connecting the device, the status of the existing wiring should be taken into account. If she is not able to provide the necessary voltage to the device for its adequate operation, it is best to replace it. Then, when gaining speed or turning on the heating element, the machine will not work, and the wiring will cope with the supply of the required voltage of 210-220V. And the device lock will not start. If the outlet into which the cord of the machine is connected is faulty, then it must be replaced. Then the cause of the breakdown will be fixed and the machine will work adequately at any time of the day.
- Connect your device only directly using a voltage regulator. Do not connect the device through tees, carrying (extension cords).
Have you followed all the detailed recommendations yourself? Does the malfunction continue to be displayed on the screen? The machine did not start working? Then you need to seek professional help. As a result of performing a specialized check with the help of professional equipment, our craftsmen will determine the cause of the Uc fault and eliminate it.
