What does the pf error mean in an LG washing machine? Causes of the error and ways to eliminate it

The PF error in an LG washing machine may appear during a specific program or quite often and without any pattern. In any case, after the first occurrence, you need to reboot 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 presented material.

Main reasons

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

But if your LG washing machine continues to show the PF error, it is recommended to unplug it for a few minutes. After this, the plug is again inserted into the socket, and then the washing should start as usual, without the code appearing.

It is useful to know what the PF error means in an 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 a specific program, and during each washing cycle;
• the PF error occurs in different programs, and also during any washing cycle;
• The PF error in an LG washing machine occurs quite often, but there is no specific pattern;
• finally, it may be that during the washing process the RCD breaks, the electricity in the entire apartment is turned off, and after turning on the LG washing machine gives a PF error.

Control module malfunction

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

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

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

Noise filter faulty

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

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

If the filter fails, the device turns off. Moreover, even if the LG machine shows a PF error, the washing process itself does not start.Then you need to test with a multimeter, switching the device to voltage measurement mode. There are 2 options:

• the voltage gives readings at the input, but there is no voltage at the output - then the filter is broken, so repairs are required;
• voltage appears at the output, but it is not at the input - the part is working properly, and the reason must be looked for elsewhere.

Faulty wiring or heating element

When the Elgie washing machine gives a PF error, this may also be due to problems with the wiring. Due to frequent vibrations and rocking, the wires fray and wear out. In the private sector and in rural areas, they can be chewed by mice. To determine the affected area, you need to “ring” all the elements in the circuit, and then, if a faulty wire is detected, replace it.

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

Preventing the occurrence of errors

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

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

1. Install a stabilizer that will absorb the voltage surge.
2. Use a separate outlet for the washing machine, to which a dedicated electrical wiring line with its own automatic machine is connected.
3. Protect wiring from rodents.
4. Constantly ventilate the room where the machine is located to avoid high humidity.
5. While the device is operating, do not connect devices that consume a lot of electricity, such as electric kettles, to the network. Otherwise, this can also lead to voltage surges.
6. Insert the plug firmly into the socket, making sure that the wire does not come away from it. If necessary, inspect it carefully to make sure there are no creases or bends.
7. You also need to carefully inspect the outlet - there should be no scorched area on it, much less a burning smell.

Thus, it is quite possible to prevent the occurrence of a PF error.
But even if it appears, it is recommended to reboot, inspect the cord and outlet, and then try to determine the exact cause. If this is not possible, contact a qualified professional. It is important to understand that DIY repairs can lead to even bigger problems.
