Pf error in LG washing machine

The pf error occurs in the LG washing machine infrequently, but this can happen at any time, regardless of washing mode. The built-in system diagnostics device detects the problem and focuses on finding its solution. The elimination of this kind of damage can not be postponed, because it is associated with faults in the electrical network of the apartment or the equipment itself. Delay can lead to unpleasant consequences in the form of expensive repairs.

What does pf error mean?

The error code pf indicates that during the execution of the work program there were problems with the power supply on the control board. If this happened only once and never happened again, then it is most likely that the temporary power surge mains or short-term power outage.In this case, the wash can be continued by simply pressing the “Start” button.

In many cases, the appearance of this error on the display is caused by poor-quality electricity supply of the apartment or house.

If everything is in order with the electrical network, then the problem lies in the machine itself, and this is already a serious case. To repair a washing machine, you must have special knowledge and skills. The best way out of this situation is to contact the service center. Its experts will eliminate the problem, give advice on the proper operation of equipment for the future.

When does it appear

A pf error in the LG washing machine may occur under various circumstances. They should pay attention, because it will help determine the cause of the problem. The code on the display may appear in the following cases:

• when turned on;
• constantly when the same program is launched;
• each time it is washed, regardless of the mode selected.

Regularly appearing an error message without any connection with circumstances is the most uncertain case in which many possible problems should be checked to eliminate the cause.

Causes

The causes of the problem that caused the flashing of the pf error on the display of the machine can be divided into external and internal. The first are power outages, from which the apartment is powered (or a house).

1. Periodic voltage imbalance of the network: its increase by more than 5% of the operating value for the device, or a decrease in excess of 10% of the norm.
2. Short power outages.

Reducing the voltage causes the simultaneous inclusion in the network of powerful electrical appliances, such as electric furnaces, kettles, welding machines and others.

Internal reasons include the following:

• damage to the plug or power cord a washing machine, which leads to the appearance of the pf code in any operating mode, at any stage of the process;

• control chip failurewhich also causes an error without being bound to circumstances;
• violation of the integrity of internal wiring home appliances between the control module and the noise filter, resulting in a stop occurring at any short-term opening of contacts;
• heating element burnout with the occurrence of a circuit on the body of the machine.

In the latter case, knocks out a residual current device (RCD) or a differential automatic switch (difavtomat). After switching on - the pf code appears.

Error Correction Options

Problems with the power supply network are often not dependent on consumers, but are caused by malfunctions or misalignment on the line. To check voltage value, you must use a multimeter or tester. To do this, do the following:

• set the instrument switch to measure ac voltage;
• check its value by touching the probes to the socket contacts.

If the device shows a voltage value of 10% more or less than 220 V, then the cause of the error is clear.

Damage to room lines is also possible. To eliminate them you need to independently understand the electrician or use the services of a specialist.

To ensure the normal operating conditions of the washing machine, the following recommendations should be followed:

• at the same time not to include several powerful electrical appliances;
• for a washing machine to bring from a separate machine own line, having a grounding conductor, and not to use common sockets, extension cord.

Installing a stabilizer is an optimal solution to the problem of poor-quality power supply, eliminating voltage drops. At the same time, its high or low value is reduced to a normal value. Read how to pick up the RCD here.

As for the machine itself, its repair is recommended in the following sequence:

• to eliminate software failure, the machine must be turned off for 15 minutes, and then turned on;
• then you should check the power cord with a plug visually and with a multimeter for integrity, and in the event of damage, replace them;
• then it is necessary to “ring out” the internal electrical circuit of the device, the noise filter, to determine the reliability of all connections, if an open circuit is detected - replace the wire;
• then, using a multimeter, you should visually determine the operability of the electronic controller and, if necessary, solder its elements or tracks or install a new control module;
• the last check the heater, which indicates a malfunction knocking diphiftomata, the appearance of the code

To check the details of the washer, you will need take it apart and then collect. At the same time, they act according to the following algorithm:

• power off;
• remove the back case cover;
• disconnect the filter, the heating element, the individual wires of the electrical circuit;
• when faulty parts are detected, they are replaced, twisted of individual conductors;
• connect all contacts into place;
• set the cover.

Analysis of various models has its own nuances. Along the way, you will need to remove various parts that will interfere with the normal access to the repaired units. In order not to forget and not to get confused - it is recommended to take periodic photographs.

As can be judged from the above problem solving algorithm, perform washing machine repair yourself - This is not an easy task, especially in the absence of relevant knowledge and experience. Often the appearance of the pf error is caused by a failure of the control module, which is difficult to repair without having certain skills. If you are not confident in your own skills, then it is better to resort to the help of specialists. Incorrect, careless actions can exacerbate the problem, leading to even greater troubleshooting costs.
