Household appliances, sooner or later cease to create comfort. Coming into contact with a fridge, washing machine or dishwasher, you can receive an electric shock. Most often it is stiralka electric shocks. From such a failure must be disposed of as soon as possible.
Even a small electric shock is hazardous to health. If the washing machine started to beat the current, immediately call a specialist. It will determine the cause and remedy the problem.
Damage to the wiring
In most cases, the washing machine has a current in the case of faulty wiring. If a damaged power cable insulation, bare wire touches the machine frame and can receive an electric shock. Facing the washing machine is made of plastic, so the problem can be seen at once.
Laying in underwear stiralku touching hands drum, you can get a severe blow. The drum has a shock because the stainless steel from which it is made, is a conductor. In the breakdown of the power cable to the body, touching it becomes unsafe.
High humidity in the room
Another cause of the fault may lie in the high humidity of the room. This occurs even in new cars, as they are designed for connection to the grounding. Most apartment buildings wiring is made of two-wire and grounding is not provided.
Condensation is deposited on the inner surfaces, creating a conductive layer between the terminals and the housing, whereby when touching cars will be felt tingling.
PETN or defective motor
The reason that the washing machine has a current can be covered in PETN is damaged or the motor. PETN shell may burn or mechanically damaged by the scale. calcium and magnesium salts in the wash water at elevated temperature to form a scum layer. If it is not clean, it can damage the lining of PETN.
Conductive filament can contact the body of the machine and an electric shock will be felt. The engine may occur a short circuit or breakage in the windings. Because the contact damaged conductors is a fire hazard.
No grounding
In many apartment buildings electrical wiring is done on two-wire circuit without grounding. Household appliances designed for the connection of three-wire with a grounding wire, when a portion of the stored charge is discharged through the housing with the capacitor to the ground.
If the ground is not in the house, on the body will gradually accumulate charge. While in contact with the car will feel a slight tingling sensation.
elimination
Faulty wiring can be fixed by yourself. Visually define the damaged area and carefully insulate it. If, before the entrance of the cable car a whole, remove the back cover, check the cables and connections inside.
Breakdown PETN or allow the engine to determine the skilled person. Do not repair these components yourself.
In order to prevent occurrence of malfunction can be reduced. Crane feeding water into the washing machine must be provided with a filter.
Periodically clean stiralku from scale: pour into a receiving tray for washing powder 50 g citric acid and in turn on the machine at a maximum temperature of the washing program and mode. Upon completion of the drum and the heating element will be sparkling clean.
Make quality grounding. If the ground is, but stiralka continues to beat the current, check all of the grounding circuit: conductors and connections. To make ground in the apartment, a qualified electrician.
Methods of protection from the high voltage
Use of RCDs
For the protection of household electrical appliances from damage due to current leakage, install a residual current device - RCD. To choose the right device for the whole apartment, determine the total power of all electricity consumers, and select the appropriate RCD.
The device is activated if the leakage current exceeds the allowable value. In case of the washing machine can select RCD nominal leakage current for which 10 or 30 milliamperes.
If the RCD is set to the two-wire network, it will often be triggered.
If it was delivered at the distribution board next to the machine, each time the electricity will knock on the apartment. To machine did not work too often, install the socket with integrated RCD will trip and only connected thereto device.
alternative methods
If the washing machine is installed in a room with high humidity, try to move it in a room with a dry air. After each wash, unplug the machine from the network. Damage to the power cable lead to undesirable consequences.
What not to do
Do not look for the fault when the power cable to the network.
When the two-wire circuit wiring do not turn the plug in the socket - it will not work. The rubber mat from the current attacks will not help.
Do not disconnect the mains filter of the washing machine. He discards part of the electricity in the building, but the problem is not in it.
In no case do not self-grounding by connecting a grounding bus to the radiator or to a water pipe.
All washing machines are designed for connection to a three-wire network. Manufacturers give to their equipment up to 15 years guarantee. Machine to serve a long time, need periodic maintenance and proper use.
