LG washing machine knocks out machine when turned on

LG washing machine knocks out machine when turned onIt is unpleasant and dangerous if the washing machine knocks the machine when it is turned on. The user does not even have time to choose a program and start a cycle: the just-lit indicators immediately go out, and the whole light turns off in the room. Rebooting will not solve the problem, because there is a clear problem. What is to blame for what is happening and how to eliminate the trouble?

Power grid or washing machine?

Such a wiring reaction to turning on the washer is very dangerous. Firstly, the machine itself is at risk, the control board of which does not like sudden voltage drops. Secondly, due to surges in the network, the insulation of the cores can also suffer, which threatens with a short circuit and fire. Thirdly, the malfunction itself threatens with unpleasant consequences - without eliminating the breakdown, the risk of a repetition or aggravation of the situation is high.

Therefore, it is important to immediately understand who is to blame: automatic or wiring. If the LG washing machine knocks jams, you will have to consistently check the main problem areas. There are several possible “sore points”, so with an active guarantee for diagnostics, it is better to contact the professionals in the service center.

Another thing is when the wiring fails. In this case, it is necessary to call the electrician or independently inspect all power circuits outside the washing machine. Most often it is in the weakened contacts that the reason for knocked out traffic jams lies. We suggest not to hesitate and immediately begin the diagnosis.

Check wiring

First of all, pay attention to the wiring. Several malfunctions lead to automatic shutdown of the machine or knocking out traffic jams.

Self-disconnection of electricity is a necessary measure to protect the premises from short circuit or current leakage.

  • Poor, unsuitable or unregulated RCD. The most common problem, leading to a power outage in the room, even with a slight load on the network. You can solve the situation by purchasing a device with a larger capacity, from a trusted manufacturer or adjusting a defective part.
  • Disproportionate load on the meter. The wiring is designed for specific capacities and if the permissible value is exceeded, an emergency shutdown occurs. For example, not everyone can afford to simultaneously turn on the refrigerator, washing machine, microwave and electric stove. There are two ways out: replace the entire power supply network with a more reliable one or operate the devices in turn.there may be a problem in the wiring
  • Damaged network. It is possible that in a certain section of the circuit there was a wire break, a violation of the integrity of the insulation or the outlet. It is easy to verify the assumption - we turn on a device similar in power and look at the reaction of the machine. If the situation repeats, then we call the electrician.

As a rule, only professionals solve problems with apartment electricity. To work with wires, machines and meters requires high qualification and great practice. Otherwise, the risk of error, overheating and fire is high.

Possible problems with the machine

If there is no problem with supplying electricity to the apartment, therefore, the reason lies in the washing machine. To correct the situation, you have to disassemble the unit, inspect and conduct the necessary diagnostics. But before you climb under the washing machine’s case, you should disconnect it from the network and drain the remaining water in the machine through an emergency drain. Otherwise, there is a high risk of electric or mechanical injury. After taking care of our safety, we study the list of possible problems that lead to the machine being turned off:

  • damaged power cord or plug;
  • induced short circuit of the heating element;
  • faulty surge protector;
  • broken engine;
  • failed interference filter;
  • idle control buttons on the dashboard;
  • frayed internal wiring or loose contacts.need to change the surge protector

Checking should begin with the most frequent and simplest, moving to the most expensive and less frequent breakdown. Ideally, it is better to immediately contact the professionals for a comprehensive diagnosis of the machine. But you can cope on your own if you follow the instructions below.

Plug or power cord?

Repair begins with an inspection of the supply wire and plug. As a rule, in illiterate operation, the power cord is often stretched, squeezed, or overlapped, which affects the flow of current into the unit. In other words, the plug and socket are not in good contact, and the machine is not able to work at full strength. It’s easy to check the cord - pierce it with a multimeter. If damage is noted, then replacement is required.

  1. We make sure that the machine is disconnected from the power supply.
  2. Close the inlet valve.
  3. We drain the water using emergency drain.

Turning the washing machine over while trying to drain the water is strictly prohibited!

  1. We unscrew the bolts holding the rear panel.
  2. We find the surge protector and remove it from the machine: press the latches, remove the plastic stopper and squeeze out of the case.
  3. Carefully remove the wire from the washing machine.may need replacing the plug

All that remains is to purchase a new cord, showing the old one as a sample in the store. After we install the wire in place, following the instructions in the reverse order. At the finish, we check the correctness of the work performed by running a test wash.

A heating element

Unauthorized heating elements can also lead to automatic shutdown of the machine. Poor and too hard water leads to strong scale, layering of impurities and chemicals on the heater, which ultimately provokes overheating of the element and internal circuit. The wiring responds to leakage by knocking out the meter and plugs.

To check the heater, disconnect the cord and measure the resistance with a multimeter. We set a limit of 200 Ohms on the device, we hook the probes to the contacts and evaluate the result on the board. Normally, the indicator should not exceed the mark of 20-50 Ohms.

This is not all: it is necessary to exclude the external “circuit”. Alternately, we measure the outputs on the heater and grounding bolts with a multimeter. Normally, the indicator will be zero, since even low values ​​indicate a problem. In case of obvious malfunctions, the heater should be replaced. You can do this yourself if you stick to the following algorithm:

  1. remove the back panel;
  2. find a heater;
  3. unscrew the retaining bolt;
  4. use a screwdriver to pry the heater and remove it.

It is necessary to act as carefully as possible. By tightly clamping the nut, it is easy to squeeze the element out of the tank or damage the contacts.heater check and replacement

Motor or surge protector?

The surge protector is responsible for stabilizing the voltage, so it is logical that during oscillations it responds by knocking out an RCD. If this happens, then the part needs to be replaced. A clear sign will be the melted contacts, as well as negative results on the multimeter display.

When an electrical wire is built into the filter, both elements must be replaced.

Also, the wiring on the motor is disconnected due to prolonged use, a damaged tank or hoses. To check, we call the engine with a tester, and with a fixed deviation, we repair or replace it. Erased electrobrushes can fail, but here it’s easier - we remove the old ones and install new ones.

Contacts or wiring?

Under suspicion and the power button, often used in the operation of the unit. In old typewriters, her condition is immediately visible: if the contacts are worn or oxidized, then the problem is obvious. We confirm the readings of the multimeter, disconnect the panel and wiring, remove the key and set another.

We visually look for frayed electric wires. As a rule, these are found in hard-to-reach places and find themselves soot on isolation. To fix, we solder and strengthen the insulating layer on the wires."Jokes" with electricity are dangerous to your life and property. Therefore, it is impossible to ignore the signal from the RCD and try to continue the cycle - you need to find out and fix the problem.
