PF error in the LG washing machine

Error code PF means power failure: Make sure the power cord is properly secured and connected. The LG washing machine should not be connected to the multi-function socket. Check the wiring and connections.

Sometimes household appliances malfunction, and if they are equipped with a display, an error code will light up on it. If you started the LG washing machine and after a while the PF error code appeared on the control panel, then there was a power failure. This error is accompanied by a stop in washing. The PF error in the LG washing machine does not always mean that a breakdown has occurred. Most likely, the power was turned off for a short period. If this happened only once, then press the "Start" button again to continue washing, there is nothing to worry about.

If the PF error code occurs from time to time, then you need to pay attention to the following points:

• How often do voltage surges occur in an apartment? And if this is a frequent occurrence, then it is worth purchasing a stabilizer. Otherwise, the control module may burn out or the wiring may be damaged.
• Since washing machines have a high power consumption, a separate socket must be provided for them. The socket for the washing machine must be connected to a separate power line with its own separate circuit breaker. If the LG washing machine is connected via an extension cord, this can also cause the error code to appear.
• The washing machine may not work properly if the plug is not firmly inserted into the socket. If this is the case, correct the situation so that the cord does not come off during washing.
• Check the socket. The socket should not have any burnt areas on the outside, there should be no burning smell, and there should be no smoke coming from it.
• Next, check the power cord of the LG washing machine. The cord should be straight, without kinks or bends. And there should be no exposed wires sticking out of it. If the cord is frayed, it will need to be replaced.
• Try disconnecting the washing machine from the power supply for 15-20 minutes and reconnecting it; perhaps the electronic controller has failed due to power surges.
• Check the voltage in the network, it may be insufficient to power the LG washing machine.

If the washing machine regularly gives the PF error, then you should check at what stage the specified code appears. You will need to contact the LG service center and repair, since frequent shutdowns can lead to a short circuit, and this in turn will make the equipment unusable:

• The PF error in the LG washing machine appears on a specific program and with each wash.
• PF error of the LG washing machine appears during every wash, but on any program.
• PF error of the LG washing machine appears often, but without a specific dependence.
• The LG washing machine trips the circuit breaker during washing and displays a PF error after switching it on.

The washing machine is controlled by an electronic controller or control module. And if it fails, the washing machine stops and displays the PF error code. This happens regularly on one of the programs. It does not matter what program it was: "Spin", "Rinse" or "Wash". If the control module breaks down, diagnostics and repairs will be required, and possibly even replacement of the module. Only a specialist can handle this complex task.

The PF error may occur if the interference filter is faulty. The error occurs with each wash but does not depend on the selected program. The interference filter dampens electromagnetic waves emanating from the washing machine so as not to interfere with the operation of other household appliances. If the filter is faulty, it stops passing electric current through the network and the washing machine turns off. This is easily checked with a multimeter for voltage at the input and output. If there is no voltage at the output, but there is at the input, then the interference filter is faulty and needs to be replaced. Sometimes the cause may not be the interference filter itself, but loose, poorly secured contacts.

If the PF error occurs frequently, but without any particular pattern, this may indicate problems with the wiring. Damage may occur as a result of wire fraying, or due to vibration of the washing machine during operation, or as a result of damage to the wires by rodents. To eliminate the problem, the technician "rings" all sections of the electrical circuit, finds the faulty one and replaces it.

There are situations when the machine trips the circuit breaker during washing and after switching on it displays a PF error. This indicates a malfunction of the electric heater (TEN). The TEN short-circuits to the LG washing machine body and trips the circuit breaker.

To minimize the cases when you have to repair your LG washing machine, you should follow the rules for operating washing machines:

• If there are frequent voltage surges in the house, then you should connect a stabilizer to the washing machine.
• The washing machine must have a separate socket with a separate power line and its own circuit breaker.
• The LG washing machine and its wiring should be kept away from pets and rodents.
• The washing machine should be placed in a well-ventilated room to avoid damage from corrosion.
• While the washing machine is running, it is not recommended to connect other household appliances with high power consumption to avoid voltage surges.

If the PF error occurs repeatedly, you should contact the LG washing machine service center and do not delay the request so as not to aggravate the problem.
