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:
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 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 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.
