Error F2 in the Atlant washing machine

If the F2 error appears on your Atlant washing machine, it means there's a problem with the temperature sensor. Machines without a display indicate a temperature sensor problem by flashing the third indicator on the control panel. In any case, you won't be able to continue washing—you'll have to stop the cycle and run diagnostics. We suggest you learn the correct procedure and what to look for.

What does the code say?

Continuing to wash with "F2" on the display is strongly discouraged. This code indicates a problem with the water temperature control. If left untreated, the machine will simply overheat.

Error code F2 indicates a faulty temperature sensor.

A working device monitors the heating of the machine and, when a predetermined level is reached, sends a command to the control board to turn off the heating element. A broken sensor is unable to stop the temperature from rising, which leads to the heater overheating, which can lead to death. Therefore, it is important to quickly respond to the error and understand what to do to correct the situation.

We test the sensor and change it

The repair begins with diagnosing the temperature sensor. To do this, remove the device from the washing machine. The thermistor is located on the heating element, which is located at the bottom of the housing. Here's how to do it:

• disconnect the washing machine from the power supply;
• we move it away from the wall, providing free access to the back of the washing machine;
• remove the back wall by unscrewing all the holding bolts;
• find the heating element located just under the tank;
• disconnect the wires going to the temperature sensor from the common connector;
• loosen the clamp holding the thermistor;
• detach the sensor from the heating element and take it out.

After removing the thermistor, we begin diagnostics. Take a multimeter, set it to "Resistance" mode, connect the probes to the sensor contacts, and evaluate the results. When the temperature reaches 200 degrees Celsius, the reading should be approximately 6000 ohms. Next, submerge the device in hot water and monitor the display: if the reading drops and reaches 1350 ohms at 500 degrees Celsius, there is no problem.

A faulty thermistor cannot be repaired. You must purchase a similar device and install it on the heating element in reverse order.

Control board diagnostics

If the thermistor is working, then we look for the problem elsewhere. The second cause of the F2 error is a problem with the control board. The difficulty is that it's practically impossible for a non-professional to visually confirm a module failure. Faulty soldering of diodes, resistors, traces, and other small microcomponents can cause a malfunction, and the slightest error can worsen the situation, leading to disastrous consequences. It's best not to experiment and instead trust a service center.

However, you can test the board at home. The key is to be careful and know how to solder. You'll also need to prepare the following tools and materials:

• multimeter;
• soldering iron;
• rosin;
• solder.

The capacitors are inspected first. They are responsible for voltage stabilization, and when overloaded, they deform and bulge. The diagnosis is confirmed with a multimeter: if a "1" is displayed, a break is confirmed; if a "0" is displayed, a current leak is present.

Next, the resistors are checked. It's important to note the order of the elements: the first row has values ​​of 8 ohms and up to 2 A, while the second group has values ​​of 120 ohms and up to 5 A. If a deviation from the norm is recorded, then a replacement is indicated.

It is strongly not recommended to check and repair the board at home!

Error code F2 also indicates a faulty thyristor unit. This component is very vulnerable and can fail due to sudden voltage surges. To diagnose the problem, a negative resistance is set on the tester, after which the first-order LEDs are tested. The resulting value should not exceed 20 volts.

At the end, we try to identify burnt-out components. Much can be seen with the naked eye, by smelling a burning smell or noticing dark spots and melted contacts. Another option is to set the multimeter to buzzer mode and "break through" the filter. The maximum voltage in this case is 12 V.

Diagnosing and repairing the control board is a complex and time-consuming process. It's essential to proceed with extreme caution, paying attention to polarity, and avoiding damage to the thyristor ports. Again, it's best not to experiment; contact a service center immediately.
