What does pf error mean in LG washing machine? Causes of the error and how to eliminate it - Setafi

The PF error in the LG washing machine can appear during a certain program or quite often and without any pattern. In any case, after the first appearance, you need to restart the unit, and if it occurs again, take repair measures. How to establish the cause, and what to do in different cases, is described in detail in the material presented.

Main reasons

If LG gives a PF error for the first time, most likely the reason is not serious. The failure could occur due to a strong power surge in the electrical network or a sudden power outage. Then you need to press the start button again and continue washing.

But if the LG washing machine continues to show the PF error, it is recommended to turn it off from the network for a few minutes. After that, the plug is again inserted into the outlet, and then the wash should start in normal mode, without the appearance of a code.

It is useful to know what the PF error means in the LG washing machine. If it continues to appear even after a reboot, you need to observe how often and under what circumstances the code occurs:

• it is observed only within the framework of a specific program, and during each wash cycle;
• PF error occurs on different programs, and also during any wash cycle;
• the PF error in the LG washing machine occurs quite often, but there is no specific pattern;
• finally, it may be that during the washing process, the RCD machine knocks out, the electricity in the entire apartment is turned off, and after turning it on, the LG washer issues a PF error.

Malfunction of the control module

Each washing machine is equipped with electronics that manages all processes (modes, information from sensors, data exchange between different elements). It is a board with numerous chips and a processor.

If this element breaks, you need to figure out what PF means on the washing machine. As a rule, when such a code appears, the unit will suspend operation, regardless of which code was selected.

If LG CMA showed a PF error, and it is presumably related to the electronic board, it is quite difficult to diagnose and repair on your own. It is necessary to determine which contacts are burned out or oxidized, then replace them.

Noise filter defective

The LG washing machine also shows the PF code when the noise filter breaks. In such cases, the code will be shown on the display during each cycle, regardless of which program is selected.

The noise filter performs an important function - it serves as an absorber of electromagnetic radiation that comes from the washing machine. If there were no such detail, these waves would interfere with other household appliances.

In the event of a filter failure, the device switches off. Moreover, even if the LG machine shows a PF error, the washing process itself does not start. Then it is necessary to test with a multimeter by switching the device to the voltage measurement mode. There are 2 options:

• voltage gives readings at the input, but it is not at the output - then the filter is broken, so repair is required;
• voltage appears at the output, but it is not at the input - the part is working, and the cause must be sought elsewhere.

Wiring or heater faults

When Algie's washing machine issues a PF error, this may also be due to wiring violations. Due to frequent vibrations and swaying, the wires are frayed and worn out. In the private sector and in rural areas, they can be gnawed by mice. To determine the affected area, you need to “ring out” all the elements in the circuit, and then, if a faulty wire is found, replace it.

It may also be that the PF error code on the LG washing machine appears due to a breakdown of the heating element, that is, the heating element. It closes to the body of the unit, because of which it knocks out plugs in the meter, and the electricity is turned off. Then you need to disassemble the device, remove the front or rear panel (depending on the location of the heater) and replace it.

Error prevention

Now it’s clear what PF means on an LG washing machine. Such a code appears in the event of a failure of the electronic module, malfunctions of the noise filter, wiring or heating element. At the same time, it is not always clear what to do if the LG washing machine shows a PF error. Simple repairs can be done by yourself. For example, it is quite possible to replace a heating element at home.

However, repairing the board or even replacing the noise filter is not always easy. Therefore, it is recommended to take all measures so that the PF LG error code does not appear:

1. Put a stabilizer that will extinguish the power surge.
2. Use a separate outlet for the washing machine, to which a dedicated electrical wiring line with its own machine is connected.
3. Protect wiring from rodents.
4. Constantly ventilate the room where the machine is located to avoid high humidity.
5. During operation of the device, do not connect appliances that consume a lot of electricity, such as electric kettles, to the network. Otherwise, this can also lead to power surges.
6. Firmly insert the plug into the socket, make sure that the wire does not leave it. If necessary, inspect it carefully to make sure there are no creases or folds.
7. You also need to carefully examine the outlet - it should not have a scorched place, especially the smell of burning.

Thus, it is quite possible to prevent the occurrence of a PF error.
But even if it appeared, it is recommended to reboot, inspect the cord and outlet, and then try to establish the exact cause. If this is not possible, please contact a qualified technician. It is important to understand that self-repair can lead to even bigger problems.
