It happens that the hostess accumulates a very large amount of dirty laundry, and her washing machine suddenly refuses to work. Then its owners have a big problem. It becomes especially disturbing if the light does not even burn in it.
Most often, this situation is amenable to self-correction without the help of a service technician. But the repair of the machine must be carried out correctly with a full understanding of what kind of malfunction is present in this particular case. Therefore, it is necessary to provide a set of instructions that will consider the most common causes of failures in the operation of the unit and the proposed methods of dealing with them.
In order to make sure that the device is working properly, you should first check the condition of the power supply. Sometimes it happens that the wire just shifts and moves away from its place. Naturally, if it is not fully connected, then the power supply of the device will not be realized. That’s why the light won’t come on.
It is also required to inspect the outlet to which the equipment is connected. It will be useful to try connecting it to another system to see if it actually works.
It is also very important to check the switch that controls the washing machine.
First, you should find the main distributor for the whole house and find the one that is responsible for the unit. Naturally, it is necessary to understand electrical engineering in order to understand whether the cause of the malfunction lies here or lies in something else. It is necessary to turn the system off and on in order to restart the washing machine and let it enter the working state again.
When operating units from LG, Samsung and Whirlpool, this problem is not uncommon. Most often it occurs due to power surges.
In order to verify that such a thing has happened, access to the main control board is required.
The algorithm of actions in this case should be as follows.
As already mentioned, with the integrity of the fuse, you should deal with the main control board.
To do this, you need to access the corresponding panel in the same way as in the previous case.
First you need to unplug the washing machine from the mains. Then you need to push it out so that it is convenient to work with the back panel. If there is not enough space, then shut off the water supply and separate the hoses.
Then you need to remove the fasteners that hold the back panel and examine the boards. Therefore, you should first learn to distinguish between the one that is intended for nutrition and the one that is responsible for management. They must be closely examined and any damage found, for example, signs of burnout.
If everything is fine, then you need to turn on the machine and check the usefulness of the electricity supply. Such actions should be carried out carefully, since any wrong movement can provoke an electric shock.
It is also required to investigate the condition of the main board. Control over it is necessary to check the presence of an LED indicator that signals the supply of electrical power.
It is also worth monitoring the voltage level supplied to the main board. In order to do everything without errors, it is better to follow the instructions for the machine. Using it, you must also check the degree of voltage at the output of the board. If tests No. 9 and No. 1011 show that it is too high, you need to change it to a new one.
After monitoring the condition of the fuse and the main control board, the next step is to monitor the safety of the user interface board. It is located behind the machine control buttons.
The problem is solved like this:
This part helps to reduce the electromagnetic noise that occurs during the operation of the washing machine. Its burnout can cause a lack of light or problems with the supply of electrical power. Most often, such failures are found in LG units. Usually, troubleshooting such a malfunction does not become unnecessarily complicated and does not take a lot of time. You only need to follow a few steps to resume the full operation of the household appliance.
First, as in all previous cases, it must be disconnected from the power supply and ensure that there is no interference with future work with it. Then it is necessary to turn off the water supply.
After gaining access to the back of the device, remove the top of the device and locate the filter assembly inside. Usually it is located in the side part near the back wall. The part is detached from the screws, and then when you press the latches, two wire connectors open. They need to be connected to a new node.
After that, you should attach it to its original place on the side of the washing machine and bring it into a functional state. The recommendations given here relate to the most common causes when the units are deprived of electrical power and the lights do not light up in them.
