What does the PF error mean in an LG washing machine, how to find the problem and fix it?
Malfunctions may occur in the operation of an LG automatic washing machine, which the equipment itself most often notifies by the appearance of a certain coding on the display.
This could be PF, among others. Such a message is accompanied by a stop in operation and requires taking measures to restore the functionality of the washing machine. This requires high-quality diagnostics and then repairs.
What does the PF error mean in an LG washing machine, how to find the problem and fix it, we will tell you further.

Decoding the code
PF coding on display tells the user that a power failure has occurred. Such a signal is a fairly rare error, and it is not always a sign of a breakdown. Very often it is associated with unstable voltage in the network.
Causes, diagnosis and repair
You should be wary of the situation when an error appears on the display not for the first time. Its occurrence may be:
- unsystematic - from time to time, but without pattern;
- on different programs at each cycle;
- when choosing a specific mode, in each wash.
All work that is planned to be carried out with the condition of partial disassembly must be carried out when the washing machine is disconnected from the water supply and electricity.
Failures not related to device failure
If the PF error code repeats, you should check how correctly the equipment is connected to electricity.
It is advisable that the socket be wired separately to a specially designated 12A machine, and the wire was 2.5 mm. Such stringent requirements are explained by the fact that the automatic washing machine consumes high power during operation.
The use of extension cords is not recommended. The cord, plug and socket must be in good working order. The plug is securely inserted into the outlet. If damage is detected, it is necessary to eliminate the defects.
If all the conditions for correct installation of LG are met, it is recommended to turn off the power to the washing machine for 15-30 minutes, and then turn it on again. If the failure on the control board was accidental, operation should be restored.
It is also necessary to check the network voltage. If it is lower than the manufacturer recommends, malfunctions may occur.
Problems with the noise filter
The interference filter is a device that is located under the top cover of the LG washing machine. Its task is to dampen electromagnetic waves from the washing machine so as not to interfere with the operation of other devices - TV, computer, etc.
Since the filter is a link in the electrical circuit, if it breaks down or the contacts come loose, the entire washing machine may malfunction. It is even possible to diagnose the filter yourself.. To do this, you need to remove the top cover and disconnect the part from the wires.
Damage to the electrical wiring in the washing machine body
If the LG display shows an error code PF on any program, and the machine freezes at any time after starting work, this may indicate a problem in the wiring. Damage can occur as a result of chafing of wires, damage due to vibration during operation, or damage by rodents.
After finding the damaged area wiring functionality needs to be restored. If the condition of the wires is deplorable, then the entire cable is replaced. For small defects, twist and insulate the area.
The heating element burned out
Often the heating element is to blame for the failure. If during the washing process the machine is knocked out, and after turning it on again, the PF code is issued, this may indicate problems with the heating element.
To diagnose the condition of the heating element, it is necessary to gain access to the part. This is possible by partially disassembling the washing machine and removing the back wall. The heating element is located at the bottom of the tank.
To carry out diagnostics, it is disconnected from the contacts and the screw is unscrewed. After this, the heating element is carefully removed and checked with a multimeter. A faulty heating element cannot be repaired - it is replaced with a new one.
Before installing a new part, it is advisable to illuminate yourself with a flashlight, clean the lower part of the tank, where the old heating element was located, from debris.
The control module is broken
An electronic controller is an element that controls the washing machine. If this module fails, the PF error may appear at any stage of the cycle - during washing, spinning or rinsing.
To carry out repairs, the board must be disconnected from all contacts and removed. If such work is carried out by a non-professional, then photographs should be taken at all stages in order to subsequently correctly connect the removed part.
Repairing the board requires a special tool. and electrical knowledge. If you do not have such experience, it is advisable to entrust the work to a professional.

Calling a specialist: where to find and how much will it cost?
If your washing machine malfunctions and you cannot fix it yourself, It is recommended to seek help from a company that repairs household appliances. You can find such a company on the Internet.
The cost for performing certain types of work can be found in the price list on the company’s website or checked with the dispatcher. The price depends on the complexity of the breakdown and may vary by region and city.
On average, repair work for the capital (without the cost of new parts) will be within the following limits:
- repair of the control module - about 2,600 rubles;
- replacement of a cable loop - about 2,000 rubles;
- replacing a heating element - about 1,800 rubles, etc.
After the repair, the technician performs a test run of the washing machine and gives a guarantee for the work performed.
10 recommendations to help
When diagnosing and repairing an LG washing machine The following expert advice may be useful:
- If you replace a part with a new one, you must make a choice based on the model of the washing machine, since spare parts from other washing machines, even from the same manufacturer, but selected by eye, may not be suitable.
- To carry out partial analysis and diagnostic measures, you will need tools, the acquisition of which should be taken care of in advance. The minimum is a multimeter and a set of screwdrivers.
- You cannot disassemble a washing machine that is under warranty yourself, as it is sealed. In case of any malfunctions of the new equipment, you need to contact the service center.
- A repeated error is a reason to conduct an analysis and determine the original source of the problem. This situation should not be left unattended, as this will only worsen the situation and increase the likelihood of more serious breakdowns.
- If you are not sure that you can carry out the repair yourself, it is better to call a specialist.
- During operation of the washing machine, it is not recommended to simultaneously connect other high-power devices.
- The electrical cord connecting the washing machine should be protected from pets and children.
- If the washing machine is installed in a room with a high level of humidity (in the bathroom), it is advisable to use special sockets with protection against moisture.
- If possible, you can install a protective shutdown mechanism in your apartment, which is triggered when there is a current leak on any equipment in the house and turns off the power.
- When removing the old heating element, you must act very carefully so as not to damage the seat of the part. If it is damaged, repairs will become many times more costly financially and technically more complex.

Conclusion
In cases where an LG washing machine issues an error code PF, it is necessary to analyze the electrical condition and also pay attention to the functionality of the heating element.
Some breakdowns can be fixed without a technician, but in difficult cases it is advisable to entrust the work to a specialist.
