When you turn on the washing machine knocks machine

electric wires You are familiar with the situation: when you turn ons washing machine, all the lights go out and the room is turned off electricity? Probably knocks cork or RCD.We will explain why the machine knocks out when turning on the washing machine and what the cause of the malfunction is.

Problems with the mains or in the washing machine?

In order for the network overload or malfunction in the car to not finally destroy the equipment, you need to establish why the meter knocks out and eliminate the cause of the malfunction.

When the washer is under warranty or a replacement of a complex electro-node is needed, diagnostics and repairs should be carried out by specialists.

But perhaps the problem is in the power supply or in the contacts? Before you call the master to the house, you need to figure out why the meter knocks out when you turn on the washing machine.

First, you need to disconnect the appliance itself and household appliances from the mains and conduct an inspection of the power circuits outside the washing machine.

Knocks out the plugs when turning on the washing machine: look for the cause in the wiring

Because of the power supply system, the RCD autodite knocks out in the following cases:

• When the RCD is of poor quality, small capacity or incorrectly adjusted. This is the most common option, it is possible when you turn on any function of the washing machine, even when draining water. To forget about the problem, it is enough to adjust or replace the machine itself.(See also: How to choose an automat( RCD) for a washing machine?)
• Increased load on the counter. When you turn on the machine, you must turn off other powerful electrical appliances, such as a microwave or electric stove.
• Violation of the integrity of the wiring or outlet. To check them you need to connect the appliance of the same power. When the RCD circuit breaker crashes, the reason is in the wiring.

Specialists should carry out adjustment or replacement of RCDs. Otherwise, unauthorized intervention in the machine, counter or traffic jams is fraught with overheating of the electrical network and ignition.

What you need to take into account in laying the

electrical network The washing machine will function smoothly and reliably if the power supply to the outlet is properly arranged:

1. experts recommend using a 3x2.5 cable in the power line installation with a margin;
2. socket should be protected from water, especially in a room with high humidity;
3. , if possible, it is better to connect the RCD isolated machine to the washing machine or to partition each room.

Knocks out the plugs: the cause of the problems in the washing machine

So, the above options are checked and not confirmed, therefore, the reason in the machine itself.

Before diagnosing or inspecting the device, de-energize the device, make sure that there is no water left in the washer. Otherwise, there is a high probability of electrical and even mechanical injuries, since the washing machine has rotating components and assemblies.

There are several reasons why a plug, a RCD circuit breaker or a counter is knocked out:

• due to damage to the plug, power supply cable;
• as a result of the closure of the heating heater;
• due to mains failure;
• due to a faulty engine;
• due to faulty noise filter;
• as a result of a control button malfunction;
• due to damaged and frayed electrical wires.

Damage to the power cord, plug

Diagnostics always starts with electrical wiring and plug. During operation, the cord is subject to mechanical stress: it stretches, overlaps, and clamps. As a result of the damage, the plug and the electrical socket are in poor contact.

The wire for damage is checked with a multimeter. Replacing the power cord is as follows:

1. it is necessary to de-energize the washing machine, close the inlet valve;
2. using a hose to ensure the discharge of water( turning the washer is strictly prohibited);
3. screws, located on the perimeter to unscrew, remove the panel;
4. remove the surge protector from the case by unscrewing the screw;
5. to press the latches, remove the plastic stopper, squeezing it out;
6. to move the electrical wire inwards and sideways, thereby gaining access to the filter and de-energizing it;
7. carefully pull the power cord out of the car;

In order to install a new cord, you need to perform these steps in reverse order.

. Short circuit of heating TENA

Due to poor quality water and chemical means of TEN, it is “eaten up”, various impurities and scum are layered. The heat transfer deteriorates, the heating element overheats and a short circuit occurs. As a result, knocks counter and traffic jams.

To test the heater, unplug the power cord and measure the resistance with a multimeter, setting a limit reading at “200” ohms. Normally, the resistance should range from 20 to 50 ohms.

Sometimes TEN "closes" on the body. To eliminate this cause, alternately measure the outputs and grounding bolts for resistance. Even a small multimeter indicates a short circuit, and this is the reason for shutting down the RCD.

To replace the heater you need:

1. remove the back panel, if the device is located at the back. If the heater is in front, first remove the control panel, then the front cover;
2. unscrew the nut of the grounding bolt about 6 turns, drown the bolt inside;
3. using a screwdriver to pry the heating element and carefully remove it;

In the process of replacing the heating element, the nut must not be tightly clamped, as it is possible to squeeze the heating element out of the tank.

Malfunction of an

mains filter. The filter is necessary in order to stabilize the electrical voltage. Network oscillations knock the node down, turning on the washer knocks the plugs and the RCD machine. In this case, the filter needs to be replaced.

Reflow elements on the contacts indicate that the power filter is closed. The filter is checked by ringing the input and output wires with a multimeter.

In some models, an electrical cord is built into the filter and must also be replaced.

Failure of the engine

The reason for the short circuit of the electrical wiring of the engine occurs during long-term operation of the device or a violation of the integrity of the tank, hose. The contacts of the engine and the surface of the washing machine alternately ring up, if a fault is detected, the engine is replaced, if possible, repaired. The place of a leak is necessarily eliminated.

In addition, the plug or the automatic UZO knocks out as a result of wear of the motor brushes. In this case, they are removed by removing the contacts from the terminals. After installing the new brushes manually scroll the motor pulley. And if they are set correctly, the motor should not make a loud noise.

Malfunction of noise filter

This node is located at the beginning of the electrical circuit. Its malfunction can be established during the inspection, since after the closure there will be traces of contacts melting. In this case, the electrostatic precipitator of the washing machine must be replaced.

Malfunction of contacts and control buttons

The electric button is used frequently, therefore, the test must be started with its diagnosis. If the washing machine is not new, worn and oxidized contacts are visible during the inspection process. A multimeter checks the wires and contacts leading to the control panel, engine, heating elements, pumps and other units.

To replace a damaged button, disconnect the panel and electrical wires. Then carefully remove the faulty knop and install another one.

Broken and rubbed electrical cables

The worn-out of electric wires, as a rule, occurs in a hard-to-reach place of a washing machine. When the machine vibrates when water is drained or dried, the electric wires rub against the panels and after some time the insulation will rub off. The electrical closure on the case is the result of the automatic trigger. The locations of damage to the wire are determined visually: a deposit appears on the insulating layer, darkened areas of melting. These places require soldering and re-isolation.

In conclusion, I want to caution: if the machine is knocked out when the washing machine is turned on, the probability of an electric shock is high. It is very dangerous! In addition, even minor irregularities in the wiring of the apparatus or in the electrical grid lead to ignition.

Therefore, it is not recommended to switch on the RCD automat and continue washing, but it is necessary to identify and eliminate the cause of the malfunction.
