When the washing machine is turned on, the machine knocks out

Do you know the situation: when you turn on the washing machine, all the indicators go out and the electricity in the room turns off? Probably knocks out plugs or RCDs. We will tell you why the machine knocks out when the washing machine is turned on and what is the cause of the malfunction.

Is there a problem with the power supply or the washing machine?

In order for network overloads or a malfunction in the machine not to completely destroy the equipment, you need to establish why the counter is knocking out and eliminate the cause of the malfunction.

When the washing machine is under warranty or a complex electrical unit needs to be replaced, diagnostics and repair work should be carried out by specialists.

But perhaps the problem is in the power supply or in the contacts? Before calling the master at home, you need to find out why the counter knocks out when you turn on the washing machine.

First you need to disconnect the device itself and household electrical appliances from the network and inspect the power circuits outside the washing machine.

Knocks out plugs when turning on the washing machine: we are looking for the reason in the wiring

Due to the power supply system, the RCD breaks out in the following cases:

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

RCD adjustment or replacement must be carried out by specialists. Otherwise, unauthorized intervention in the machine, meter or plugs is fraught with overheating of the electrical network and ignition.

What needs to be considered when laying the electrical network

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

1. experts recommend using a 3x2.5 cable with a margin in laying the VVG power line;
2. the outlet must be protected from water, especially in a room with high humidity;
3. if possible, it is better to connect an isolated RCD circuit breaker to the washing machine or section each room.

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

So, the above options have been tested and not confirmed, therefore, the reason is in the device itself.

Before diagnostics or inspection, the device must be de-energized, make sure that there is no water left in the washer. Otherwise, there is a high probability of electrical and even mechanical injuries, since there are rotating components and assemblies in the washing machine.

There are several reasons why it knocks out plugs, an RCD machine or a counter:

• due to damage to the plug supplying the wire;
• as a result of the closure of the heating heating element;
• as a result of a defective mains filter;
• due to a faulty engine;
• due to a faulty noise filter;
• as a result of a malfunction of the control button;
• due to damaged and frayed electrical wires.

Damage to the power cord, plug

Diagnostics always starts with the wire and plug. During operation, the cord is subject to mechanical stress: it is stretched, overlapped, pinched. Damaged plug and power outlet are not making good contact.

Check the wire for damage 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. use a hose to drain the water (it is strictly forbidden to turn the washer over);
3. Unscrew the screws located around the perimeter, remove the panel;
4. remove the power filter from the case by unscrewing the screw;
5. press the latches, remove the plastic stopper, squeezing it out;
6. move the electrical wire inward and sideways, thereby gaining access to the filter and disconnecting it from power;
7. pull the power cord out of the machine carefully;

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

Heating element short circuit

Due to low-quality water and chemicals, the heating element is "eaten up", various impurities and scale are layered. Heat transfer is impaired, the heating element overheats and a short circuit occurs. As a result, it knocks out the counter and plugs.

To test the heater, disconnect the power cord and measure the resistance with a multimeter, setting the limit at 200 ohms. Normally, the resistance should vary from 20 to 50 ohms.

Sometimes the heating element "closes" on the body. To eliminate this cause, the outputs and grounding bolts are measured alternately for resistance. Even a small indicator of the multimeter indicates a short circuit, and this is the reason for the RCD disconnection.

To replace the heating element you need:

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

In the process of replacing the heating element, it is impossible to tighten the nut tightly, since the heating element can be squeezed out of the tank.

Defective mains filter

The filter is necessary in order to stabilize the electrical voltage. Network fluctuations disable the node; when the washing machine is turned on, it knocks out the plugs and the RCD. In this case, the filter needs to be replaced.

The fact that the surge protector has shorted is indicated by the reflow elements on the contacts. The filter is checked by ringing the input and output wires with a multimeter.

In some models, the filter has a built-in power cord, which must also be replaced.

Engine malfunction

The reason for the short circuit of the electrical wiring of the engine occurs during prolonged operation of the device or violation of the integrity of the tank, hose. The contacts of the motor and the surface of the washing machine alternately ring, if a malfunction is detected, the motor is replaced, if possible, repaired. The place of the leak must be eliminated.

In addition, plugs or an RCD breaks out as a result of wear on the engine brushes. In this case, they are dismantled by removing the contacts from the terminals. After installing new brushes, manually rotate the motor pulley.And if they are set correctly, the electric motor should not make a loud noise.

Noise filter defective

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

Malfunction of contacts and control buttons

The electric button is used often, so the test must begin with its diagnosis. If the washing machine is new, worn and oxidized contacts are visible during inspection. A multimeter is used to check the wires and contacts leading to the control panel, engine, heating element, pump and other units.

To replace the damaged button, disconnect the panel and electrical wires. Then the faulty button is carefully removed and another is installed.

Broken and frayed electrical wires

Scuffing of electrical wires, as a rule, occurs in a hard-to-reach place of the washing machine. When the device vibrates when draining water or drying, the electric wires rub against the panel and after a while the insulation will fray. Electrical short circuit on the case is the result of the fact that the machine is triggered. Locations of wire damage are determined visually: carbon deposits appear on the insulating layer, darkened areas of reflow. These places require soldering and re-insulation.

In conclusion, I would like to warn you: if the machine knocks out when you turn on the washing machine, there is a high probability of electric shock. It is very dangerous! In addition, even minor irregularities in the electrical wiring of the device or in the electrical network can lead to fire.

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