Why does the washing machine be shocked?

Even small electric shocks are very dangerous for a person, so if your washing machine beats current, be sure to solve this problem as soon as possible. The main reasons why the technique starts to "pinch" your fingers when you wash your hands or touch the drum after washing, most often are the lack of grounding of the electrical wiring or the malfunction of the machine itself. Next we will look at the main causes of the malfunction and what to do in order to eliminate the current breakdowns in the bathroom.

The absence of PE wire

The first and most important reason why a washing machine beats current is that the home wiring is not grounded. The fact is that even a new technique is designed for the fact that a small amount of current must flow from the capacitors to the grounding system of the house through the housing. As you understand, if there is no grounding, a small charge of current will accumulate on the case, and if you touch the stylalk you will feel how it beats, especially if your hands are wet. Solve this problem can only one way - to make grounding in a private house or apartment.

As for apartment buildings, there can be trouble, due to the fact that there is no ground terminal in the housing panel. Usually this can happen in the old type of Khrushchev. In this case, you need to solve the problem in a different way, which we'll talk about below.

We draw your attention that in a dry room, for example a kitchen, you can not even feel that the washing machine is beating with current. If the technique is installed in the bathroom, then you immediately feel how it beats, which is caused by high humidity in the room.

Malfunction of the

technique The second reason why the body of the washing machine is beating current is that it just went out of order. Most likely, there was a damage to the wiring somewhere inside the equipment( for example, the TEN probit).In this case, you will have to remove the lining and visually inspect all the wires and connections of the contacts. TEN call in multimeter

The found "culprit" of the breakdown must be carefully insulated with heat-shrinkable tubing or electrical tape or replaced. Immediately recommend that you familiarize yourself with what to do if the washing machine is noisy when pressed.

What else can I do?

In addition to the fact that the home network must be grounded and the equipment itself must be functional, it is necessary to additionally protect yourself in the following ways:

Connect the RCD to 10 or 30 mA.The residual current device will operate at the slightest leakage, so if the washing machine beats current, the automation will immediately react and turn off the power on the shield. We draw your attention to the fact that if the electrical wiring in the house is old and there is no possibility to replace it with a three-wire one, it may be possible that the RCD trips frequently. As a result, you will constantly walk and turn on the machine on the dashboard, which is not very convenient. In this case, it is better to install the outlet into which the protective shutdown device is mounted, as shown in the photo.
Make a system of equipotential bonding. We examined in detail the device of this system, when they talked about how to make wiring in the bathroom.
Check the integrity of the earth. Sometimes it happens that the washing machine hits with electric shock even if there is a connected "ground".In this case, the reason that it hits is damage to the grounding conductor, which will need to be checked and restored.

If you feel a slight tingle through the faucet or tap water, immediately turn off the electricity in the bathroom and go on to find the cause. With the connected voltage, to search, why the washing machine began to beat the current is strictly forbidden!

What not to do?

On the forums you can find a lot of advice "mount-electricians" who recommend solving the situation in the following ways:

If there is no grounding of the wiring, simply turn the plug in the outlet and put a rubber mat on the floor in the bathroom. This solution will not solve the problem, as a result of which, at some point, another person or you may be injured.
Disconnect the mains filter of the washing machine. Proceeding from the fact that this device sends a discharge to the case, it is considered that its disconnection will eliminate the cause of electric shock. This is incorrect, it is possible that the probability of defeat will be less, but still it will be present.
Connect the grounding conductor to the riser or the radiator from the washing machine. This version of the grounding system is dangerous and can lead to human injury by electric shock, so it should be avoided.
Remove the separate PE wire from the switchboard. Immediately it should be noted that you can not remove a separate "ground" from the shield, and plug the plug into a socket without grounding. Correct protection will be provided only if you output a three-wire cable and connect a new, safe socket to it.
