We loaded the laun­dry, start­ed the wash­ing pro­gram, and after a while we noticed that the LG wash­ing machine stopped and gave a PF error on the dis­play. What to do? What does PF error mean? How to fix the prob­lem? You will find answers to all these ques­tions in this arti­cle.


PF error on LG washing machine

The PF code means that dur­ing the exe­cu­tion of the pro­gram, most like­ly there was a jump or a pow­er out­age in the apart­ment or in the whole house. Basi­cal­ly, the prob­lem of the PF error should not be looked for in the tech­nique itself. If this error appeared on the score­board only once, then you can ignore this. The reap­pear­ance of the error indi­cates that the prob­lem is still in the wash­ing machine.

If a PF error occurs:

  • on any spe­cif­ic pro­gram every wash;
  • on any pro­gram dur­ing wash­ing;
  • con­stant­ly with­out a notice­able pat­tern.

Malfunctions that do not require the intervention of a master

  • Wash­ing machine con­nect­ed incor­rect­ly. It is nec­es­sary to check the cor­rect con­nec­tion of equip­ment. The sock­et must be sep­a­rate and with a sep­a­rate machine. It is strong­ly not rec­om­mend­ed to con­nect the wash­ing machine to exten­sion cords and sock­ets that are designed for oth­er house­hold appli­ances. The wash­ing machine is very capri­cious, so you should fol­low all the rules for its instal­la­tion and oper­a­tion.
  • Dam­age to the pow­er cord or plug. In most cas­es, this means that the cord and plug should be replaced. It is advis­able to do this as soon as pos­si­ble.
  • Fault on the con­trol board. Unplug the wash­ing machine for 15 min­utes and then plug it back in using the START/PAUSE com­mands. If it was a fail­ure, then the error on the score­board will dis­ap­pear.
  • Mains volt­age. The mains volt­age may have dropped. This needs to be checked.
  • Loose wire con­nec­tions. It is nec­es­sary to check the entire chain of wires. Maybe the con­tact is lost and there­fore the error lights up on the score­board.

The main causes of the malfunction

Symp­toms of an Error Prob­a­ble cause Repair or replace­ment
The wash­ing machine abrupt­ly turns off dur­ing oper­a­tion, rins­ing or spin­ning, and the PF error lights up on the dis­play. Con­trol board failed Most often, the mod­ule can be repaired: you can replace burned-out ele­ments, sol­der the con­tacts and tracks on the chip.

It is rare that a con­trol mod­ule needs to be replaced.

The PF error crash­es on the score­board and at any stage of wash­ing and the wash­ing machine freezes. Prob­lems with the wiring from the noise fil­ter to the con­trol board. Con­tact is lost due to vibra­tion. Twist frayed wires and iso­late or com­plete­ly replace the cable.
Dur­ing wash­ing, the machine knocks out, and after turn­ing on, a PF error appears on the dis­play. The heat­ing ele­ment (heater) is defec­tive. It clos­es to the body of the wash­ing machine, and knocks out the machine. Replace­ment of the tubu­lar elec­tric heater (TEN) is required

If you were unable to solve the prob­lem with the wash­ing machine on your own and the PF error still pops up on the elec­tron­ic dis­play, then you should con­tact a spe­cial­ist.
