LG washing machine does not turn on

SM LG does not turn onEveryone knows that in order to turn on the LG washing machine, you first need to plug the plug into the power 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, do not push the button, which means either a breakdown or a problem with the power supply. We have to check both of them in order to discover the cause of this "disgrace".

List of possible problems

Popular wisdom says: "if the washing machine behaves as if it had turned off the electricity, maybe this is so." Of course, this is a joke, but still, click on the switch in the bathroom, just in case, all of a sudden, and really a short shutdown. If the electricity is supplied to your house properly, you may have to “dig into” the following possible causes of the malfunction:

  • broken network wire;
  • the outlet that powers the LG washing machine does not work;
  • FPS failed;

FPS on LG washers often burn due to power surges.

  • the on / off button does not work.

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

We check external communications

network wireSo, 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 socket to which the LG washing machine is connected. What to do? Look into the electrical panel and check if the machine that feeds the outlet has been knocked out. Unplug the washing machine’s power cord and connect another appliance to this outlet: kettle, desk lamp, microwave. If the appliance works as if nothing had happened, then the LG washing machine is really malfunctioning.

Doesn't the power turn on? So next in line for verification, there will be a power cord. Sometimes users manage to put something heavy on the network cable, perhaps even the LG washing machine itself. What happens after that is easy to guess, the wire breaks through, and it ceases to power the equipment.

We take out the mains cable for the entire length and carefully examine it. If there is a burning or flashing on the plug or any section of the wire, it means that 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.

Remove the control panel unit

Suppose that with a network cable, everything is fine. So, the problem is hiding somewhere in the bowels of the control unit. To continue the test, we need to dismantle this block, and then disassemble it. Let's get to work.

  1. First you need remove the lid from the LG washing machine.
  2. Next, remove the powder receptacle and put it to the side.
    pull out the CM tray
  3. We take a Phillips screwdriver in our hands and unscrew the screws that are located next to the powder receiver niche on the right and left.
    remove the CM control panel
  4. We press the latches of the control unit with the same screwdriver, after which we carefully separate the unit from the case.

Be careful with the bundle of wires that connects the chassis to the control panel.

We will not remove wires yet. But if during the test you will need to completely separate the control unit from the case, then first take a picture of the location of the wires, so that then you can easily connect everything into place.

Repair FPS, transformer and on / off buttons

For now, let’s remove the control unit by putting it on top of the corner of the typewriter body. First you need to check and fix the failure of the FPS, if any. Above the housing cover, an interference filter can be detected.

FPS washing machine LG

We call him with 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 we disassemble the unit to get to the transformer. We check the tracks visually to make sure that the transformer has not decayed, and then we start ringing it with a multimeter. We found a breakdown, which means that do-it-yourself repairs will consist in either soldering the tracks or replacing the transformer, there is nothing more you can do.

CM control unit

LG direct drive washing machine may stop turning on for another reason. Why? Because of the start button. Again we take up the multimeter and call the contacts of this button, at the same time we check the start and on / off buttons. If you find a problem, grasp the 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 flashes, then the power has gone and the machine will work.
