LG washing machine does not turn on

Everyone knows that to turn on the LG washing machine, you must first plug the power cord into the outlet and then press the on/off button. The control panel will light up with all the lights and the machine will be ready to start the washing program. If the LG washing machine does not turn on, no matter how much you press the button, it means either a breakdown or a problem with the power supply. We must check both of these in order to discover the cause of this “disgrace.”

List of possible problems

Popular wisdom says: if the washing machine behaves as if there was a power outage, it probably is. Of course, this is a joke, but still flip the switch in the bathroom, just in case there really is a short-term blackout. If electricity is supplied to your home properly, you may have to dig into the following possible causes of the malfunction:

  • The network wire is broken,
  • The socket that powers the LG washing machine does not work,
  • Fps has failed,
  • The on/off button does not function.

The control module or its individual semiconductor elements could, of course, completely burn out. But in this case, you will have to contact a specialist, since it is difficult to independently detect such a breakdown without special knowledge. So, let’s check with our own hands what we can and hope that the reason turns out to be simple.

Checking external communications

So, by clicking the switch, you are convinced that there is light in the house, which means that in the second stage you need to check the outlet to which the LG washing machine is connected. What to do? Look into the electrical panel and check whether the circuit breaker that powers the outlet has been knocked out. Unplug the power cord of the washing machine and connect another electrical appliance to this outlet: a kettle, a table lamp, a microwave oven. If the electrical appliance works as if nothing had happened, then the LG washing machine is faulty.

Power won't turn on? This means that the next thing in line to be checked will be the power cord. Sometimes users manage to place something heavy on the power cord, perhaps even the LG washing machine itself. It’s easy to guess what happens after this: the wire breaks through and it stops powering the equipment.

We pull out the entire length of the power cord and inspect it carefully. If there is any burning or melting on the plug or any section of the wire, then the wire is most likely broken. But a hidden breakdown is also possible. Take a multimeter, set it to ohmmeter mode for continuity and check the integrity of the wire. The faulty wire will have to be replaced.

Removing the control panel block

Let's assume that everything is fine with the network cable. This means that the problem is hidden somewhere in the depths of the control unit. To continue testing, we need to dismantle this block and then disassemble it. Let's get to work.


  • First you need to remove the cover from the LG washing machine.
  • Next, you need to remove the powder receptacle and put it aside.
  • We take a Phillips screwdriver in our hands and unscrew the screws that are located next to the powder receptacle niche on the right and left.
  • Using the same screwdriver, we press in the latches of the control unit, and then carefully separate the unit from the body.

We won't remove the wires for now. But if during the test you need to completely separate the control unit from the body, then first take a photograph of the location of the wires so that you can easily connect everything in place.

Repair of FPS, transformer and on/off button

For now, let's remove the control unit, placing it aside on top of the corner of the machine body. First you need to check and fix the FPS failure, if any. On top, under the housing cover, you can find an interference filter.

We call it using a multimeter. If the part does not ring, it must be replaced; if everything is in order with it, we return to the block. We disconnect the wires and then disassemble the block to get to the transformer. We visually check the tracks to make sure that the transformer is not unsoldered, and then we start calling it with a multimeter. If you find a breakdown, it means that your own repairs will consist of either soldering the tracks or replacing the transformer; there is nothing else you can do.

An LG direct drive washing machine may stop turning on for another reason. Why? Because of the start button. Again, we take the multimeter and call the contacts of this button, at the same time we check the start and on/off buttons. Having discovered a problem, take a soldering iron, solder the tracks, remove the faulty buttons and solder new ones. At the end, connect the control unit and turn on the power, if the light blinks, it means the power is on and the machine will work.
