LG washing machines have a nice feature: in case of some error they show this error on the panel. And you yourself can already determine what to do with it next. It is possible that you will not even have to call a master.
One of such errors is the PF error. It can occur at any time during the operation of your washing machine. This error seems simple, but it can contain certain nuances.
So why does the LG washing machine give out a PF error code?
First, let's deal with the error itself.
Error PF occurs with unstable voltage of the electrical network. It can be:
-
What does the error code Pf in the washing machine mean? single and short-term power outage;
- Power surges in the mains with a deviation of 10% downwards and 5% upwards from the norm;
- interruptions due to the connection of other household appliances to the washing machine's power line, which may cause a power surge when switched on.
All of these are related to the power supply. More often than not, it is these causes that cause a PF error. In such cases, you can deal with them yourself or with the help of an electrician.
Here are some tips:
- In order to restore the normal operation of the washing machine after the PF error, first of all, it is recommended to turn off and on the washing machine with the START/PAUSE button.
- LG washing machines are rather finicky about the power supply. Therefore, do not use extension cords, surge protectors, etc.
- Install a separate socket for your washing machine and connect it to the power distribution board with a separate line. Use a socket with the necessary moisture protection (IP54) if you install it in the bathroom, and a copper wire of at least 2.5 mm for the supply line2.
- If your power supply line has occasional voltage spikes beyond normal limits, use a voltage regulator with at least 3kW of power.
This is what concerns your electrical network that powers your washing machine.

In addition to these causes, the PF error can still occur due to some malfunctions inside the washing machine.
In particular, the wires in the power supply circuit that connects the noise filter and the electronic controller can become frayed or disconnected.
Because of this the contact can be lost and the error will light up.
In this case it is necessary to check the wires: twist the disconnected wires and then insulate them or replace the wires.
If you have used all the above tips, but PF error has not been eliminated, it means that the problem is in the machine. And here already without the qualified help can not do. For it you can always turn to specialists and craftsmen
