LG washing machines have a nice feature: if an error occurs, they display it on the control panel. This way, you can figure out what to do next. You might not even need to call a technician.
One of such errors is the PF error. It can occur at any time while your washing machine is running. This error seems simple, but it can have some nuances.
Why does my LG washing machine display the PF error code?
First, let's deal with the error itself.
The PF error occurs when the electrical network voltage is unstable. This may be due to:
-
What does the Pf error code mean in a washing machine? one-time and short-term power outage;
- voltage surges in the electrical network with deviations from the norm of 10% downwards and 5% upwards;
- interruptions due to the connection of other household appliances to the washing machine's power line, which, when turned on, can cause a power surge.
All of this is related to the power supply. These are the most common causes of the PF error. In such cases, you can resolve the issue yourself or with the help of an electrician.
Here are some tips:
- In order to restore normal operation of the washing machine after the PF error, it is first recommended to turn the washing machine off and on using the START/PAUSE button.
- LG washing machines They are quite sensitive to power supply. Therefore, do not use extension cords, surge protectors, etc. to connect them.
- Install a dedicated outlet for your washing machine and connect it to the power distribution board via a separate line. Use an outlet with the required moisture protection (IP54) if installing it in the bathroom, and use a copper wire with a cross-section of at least 2.5 mm for the power line.2.
- If your electrical network periodically experiences voltage surges beyond the normal limits, use a voltage stabilizer with a power of at least 3 kW.
This is what concerns your electrical network that powers the washing machine.

In addition to these reasons, the PF error may still occur as a result of some malfunctions inside the washing machine.
In particular, the wires in the power supply circuit connecting the interference filter and the electronic controller may become frayed or disconnected.

In this case, it is necessary to check the wires: twist the disconnected ones and then insulate them, or replace the cable.
