In LG washing machines, the PF error rarely occurs. However, this can happen at any time. This error can appear in any washing mode. Such a breakdown must be repaired immediately, since it occurs when washing equipment or the home’s electrical network malfunctions.
If the malfunction is not corrected immediately, unpleasant consequences may occur in the future. For example, expensive equipment repairs may be required. A fault in the electrical network can cause a short circuit in the wiring in the house. Let's try to find out why the PF error appears and how to eliminate them.
Deciphering the error code
The pf error indicates that during program execution there was a power failure on the control module. If this error occurs only once, then most likely the cause of the PF code is a power surge. This can also happen during a short power outage. In this situation, you just need to press the “Start” button on LG washing machine and continue washing.
Quite often, the pf error in LG washing equipment occurs when there is poor power supply in an apartment or private house.
If the electrical network is working properly, then the reason for the pf error lies directly in the machine. This case is much more serious than the previous one. For LG washing equipment repair Special skills and knowledge are required. In such a situation, it is best to contact a service center. Our technicians will fix any problems that have arisen and also give recommendations on how to properly repair them. using an LG washing machine.
Conditions under which the PF error appears
There are a number of conditions under which this error may occur. It is necessary to pay attention to these circumstances, because they will help to find out the cause of the breakdown.
A pf error may appear on the display of your LG washing machine under the following conditions:
- at the moment of switching on;
- constantly, when starting the same washing program;
- with every wash, regardless of selected program.
The most difficult case is when the PF code appears on the display of an LG washing machine regardless of the circumstances.
In such a situation, to find and eliminate the cause of the breakdown, you will need to check many fault options.
Identifying causes
All causes of malfunction of the LG washing machine are conventionally divided into two types: external and internal. The category of external causes includes failures in the residential electrical network.
- Regular voltage imbalances in the electrical network. In other words, the PF code occurs when the voltage increases by five percent or more from the operating value for the washing machine or decreases by more than ten percent.
- Short-term power outages.
It should be noted that a decrease in voltage occurs when several powerful electrical appliances are simultaneously connected to the mains. Such devices include a kettle, microwave oven, welding machine, and other devices.
Internal causes of errors include:
- The power cord or plug of the LG machine is damaged.In such a situation, the pf code appears on the washing machine display at any stage of the wash;
- malfunction of the control microcircuit;
- damage to the internal wiring of the machine between the interference filter and the control module. The washing process stops as a result of a short-term opening of the contacts;
- heating element burnout with a short circuit to the body of the LG washing machine. In this situation, the residual current device or differential circuit breaker is triggered. The pf code appears after switching on.
Ways to resolve a PF error
Often problems with the power grid are caused not by consumers, but by problems on the line. To find out the voltage value, you need to use a tester or multimeter.
This is done as follows:
- The switch of the measuring device is set to measure alternating voltage in the network;
- Touch the socket contacts with the probes to check the voltage level.
- If the value shown by the measuring device deviates by 10% from 220 V up or down, then the reason for the PF error is obvious.
Also, the PF error can occur when the indoor lines are damaged.
A few tips to help create optimal operating conditions for LG washing equipment:
- do not connect several powerful devices to the power supply at once;
- bring your own line with a grounding conductor under the washing mashine from a separate machine.
Repairing a washing machine consists of the following sequential steps:
- First you need to turn off the LG washing machine for about 15 minutes and then turn it on. This is necessary to avoid a software failure;
- Inspect the plug and power cord of the LG machine. Then check their integrity with a multimeter. If any malfunctions are found, replace them;
- ring the electrical circuit located inside the device, check the condition of all connections and the interference filter. If a break is detected, replace the wire;
- check the condition of the electronic controller. This is done using a multimeter. If the element is faulty, then you need to resolder its tracks or elements. You can also replace the faulty control module with a new one;
- At the last stage, the heating element is checked. If it breaks down, the automatic machine is knocked out, and the error code PF appears on the display of the LG washing machine.
To check the parts of the LG washing machine, you will need to disassemble and reassemble it.
The actions are performed in the following order:
- disconnecting the device from the power supply;
- dismantling the rear cover of the machine body;
- disconnecting the filter, heating element, electrical circuit wires;
- replacing detected faulty elements with new ones. The individual cores are twisted;
- connecting all contacts to their original place;
- installation of the cover.
LG washing machine disassembly process may have its own nuances depending on the model. Most likely, you will have to dismantle some elements that will impede access to the parts being repaired.
To simplify the assembly process, it is advisable to periodically take photographs.
