It's a shame when such an easy procedure as washing things in a washing machine ends with a zero result. It all started as usual, but when the washing machine is turned on, the machine knocks out. As a result, the unit cannot execute the wash program. In order to start repairing or replacing failed parts, it is necessary to find out the reason why the device has a protective shutdown device.
Not so sad
Statistics, which are maintained in service centers, indicate that the washing machine knocks out an automatic machine, traffic jams or other RCDs not so rarely. About 20 percent of customers complain of such a problem. There are few options for breakdowns in this case, and usually two main reasons are considered:
- malfunctions in the household appliance itself;
- There are problems with the wiring.
Blame the washing machine right away. Especially if she has just appeared in the house, and in her life this is the first wash. First of all, it is necessary to check whether the power supply devices necessary for protecting the correct cross-sections of the cable were selected correctly. Maybe automatic machines or RCDs do not meet the necessary parameters of electric intensity.
Check power supply
It can pump either a socket or wiring. To make sure of this, just plug in some device into the same outlet. But it must match the same power as the washing machine. The outlet can tell a lot about the breakdown and inside the device. If the plates are very melted, then there is a strong overload. Therefore, when you turn on the washing machine, the machine knocks out. The cable is most conveniently checked with a megger meter - maybe the whole thing is in it. If the reason is this, then you should contact a professional electrician. He will pick up a cable suitable for power and install a new outlet.
What should be the power source for the washing machine?
The device will please with excellent work if the power supply from the outlet is arranged in accordance with all the rules:
- the source is reliably protected from water, and in a bathroom with high humidity this fact is of great importance;
- Ideally, there should be a connection of an isolated RCD circuit breaker;
- for reliability, it is necessary to use a VVG cable with 3 x 2.5 parameters in the electrical power supply, preferably with a margin.
If there are no problems with the power source, you should look for the reasons in the machine itself. Even in a new device, a factory defect may be hidden. You will have to use the services of a service center or replace the unit with another.
Network congestion
If other household appliances are involved in the house during the connection of the washing machine - a TV, a computer, a vacuum cleaner, an electric kettle, an iron, then the electric network may not withstand such a load. Therefore, this can be the answer to the question of why the machine knocks out when the washing machine is turned on. In this case, you also need to trust an electrician so that he can eliminate these unpleasant moments, or avoid turning on high-power devices during washing.
Cord or plug replacement required
This is the most common reason why the machine knocks out when the LG washing machine is turned on. During operation, the plug becomes unusable, and to correct the situation, it is only necessary to clean the pins. Typically, these defects are immediately visible. If cleaning at home does not help, you will have to go to the store and buy new parts. External damage, cuts may appear on the power cord. In this case, the cause of the operation of the machine will be at the very beginning of the circuit. Also, when plugged into an outlet, you must make sure that the cord does not have any contacts with any structures that are grounded.
As for the plug, even if outwardly it looks in good condition, but there are doubts about its performance, it is better to replace it with a new one anyway. Shorting may occur inside the part.
Control board malfunctioning
This is a more serious problem. If water periodically gets on the board, the contacts are oxidized. And once at the next connection, a closure will necessarily occur, as a result of which the network protection will work, and the machine will knock out. The damaged board must be repaired or replaced. It depends on how much the part was damaged, and if it can still serve, how long. Maybe it’s better to replace it right away than soon to encounter a problem again when the washing machine knocks the machine or plugs.
The heating element is out of order
The tubular electric heater during operation of the machine is subject not only to the influence of water, but also washing powders adversely affect its condition. Scales form on the spirals. As a result, a short circuit occurs , and the machine knocks out when the washing machine is turned on. In this case, only the replacement of the heating element will help.
To prevent the formation of scale, it is necessary to clean the machine with special tools, starting the wash cycle at a program of 60-90 degrees without loading laundry. Such events should be carried out at least once every six months, and if the water is hard, every three months.
The button can also cause
In any case, the machine will not work without the power button. During operation, it wears out, and the contacts are oxidized. Therefore, a short circuit may occur in this area. To solve the problem, first you can try to clean the contacts, and if it does not help, then replace the button with a new one.
Humidity inside the appliance
Electrical elements that are inside the machine can cause a large amount of condensation. This happens quite rarely, but also needs to be taken into account. It is enough to leave the car alone for several days, giving it the opportunity to dry well, and it will work again without causing any trouble.
Engine malfunction
The machine knocks out when the washing machine is turned on and in the event that a malfunction in the motor has begun. Here, too, short circuiting may occur due to leakage inside the unit. Or maybe the term of its operation has expired or an interturn circuit has occurred . The solution is to replace the motor.
Interference Filter Replacement Required
The filter also often becomes the reason why the machine knocks out when the washing machine is turned on. It is located at the very beginning of the electric circuit. If the reason lies in it, then traces of melted contacts will be noticeable. In this case, you will need to exclude it from the scheme. This requires a connection due to jumpers of the ground phase. In the event of a breakdown, the part is replaced with a new one.
A device that helps you find the cause of the malfunction
If the house has a multimeter, it will help to minimize research on the machine and its disassembly. With its help, you can identify what was the fault, why the machine is knocked out when the washing machine is turned on. For example, the electric heater will not have to be dismantled in the event of a break, since the device will show “zero”.
The machine stopped working, and even the machine knocked out? First of all, you must turn off the unit from the outlet and not try to turn it on again. Better to have an experienced specialist repair it.
A closure can result not only in the loss of a washing machine, but also cause irreparable damage to the apartment - a fire can occur very quickly. And if a person during a circuit is in close proximity to danger, then an electric shock can be obtained quite strong.
