What should I do if the Atlant washing machine diagnostics system finds a malfunction and issues an F2 error? The first step is to recognize the fault code - it means a temperature sensor problem.
Electronic models Atlant error F2 show on the display. Electromechanical washers without displays an error code like this: a third indicator lights up on the control panel.
What does the F2 error mean in the Atlant washing machine
For the Atlant washing machine, DTC F2 indicates a malfunction in the temperature sensor.
He is responsible for measuring the temperature of the water, the principle of operation of the sensor may vary depending on the type of device. But the essence is the same: when the selected washing temperature is reached, the thermostat sends a signal to the control board. The latter gives a command to turn off the heater.
Damage to the temperature sensor with an F2 error can be critical. Unregulated heating leads to boiling water and the combustion of the heater.
Types of thermal relays, checking them at home
We will figure out how to fix the problem and remove the F2 error. To solve the problem, consider the types of temperature relays and methods for checking them.
Bimetal type
Represents two bimetallic plates in the form of tablets. When voltage is applied, the plates expand, closing the contact, which is read by the control board as a signal.
Due to wear, the bimetallic type sensor fails.
How to fix the situation and install a new thermistor on SM Atlant:
- Get to the washing tank and disconnect the sensor wires.
- Attach the probes of the multimeter to the contacts and measure the resistance.
- Now immerse the thermostat in hot water, look at the readings.
- If the readings fall - the device is working. No - need a replacement.
After installing a new item, check the typewriter. See if the F2 error has disappeared from the display. If the thermostat is OK, continue the test.
Gas filled type
This sensor consists of two parts. One of them in tablet form is in water, where it measures temperature. The second in the form of a tube filled with freon is connected to the control module.
When heated, the gas expands, and contacts are closed. Damage to the tube and gas outlet cause a malfunction.
What to do to replace and fix the error:
- Remove the rear and front panel of the CMA Atlant.
- Remove the thermostat clamp from the back and push it into the tank.
- Remove the appliance from the tank by disconnecting the wires.
- With a tester, check the resistance as in the previous case.
Electronic type
An electronic sensor (thermistor) is located at the base of the heating element. The method of its work is to measure the resistance that forms when water is heated.
What does replacing a thermistor mean:
- Remove the back panel of the Atlant wash.
- Below, where the heater is located, you will see a thermistor.
- Loosen the central heating element nut, remove the thermistor.
- Resistance is measured in the same order.
The new thermostat is installed in the reverse order. Thus, you can carry out repairs yourself and remove the F2 error that is lit on the display.
Control module
If the sensor tests fail, inspect the control unit. Its elements are also called by a multimeter.
Repairing and replacing a module can be challenging for a beginner. Each element of the board is responsible for the operation of one of the details of the SM, so it is important to understand what and how to do. If you do not understand electronics, call the wizard.
After repair, start the Atlant washing machine. Pay attention to whether the water heats up normally, whether F2 is displayed on the screen. If everything is normal - you managed to reset errors and do it yourself.
