The automatic device knocks out after turning on the washing machine: understand it thoroughly
Are you familiar with the situation: when you turn on the washing machine, all the indicators go out and the electricity in the room turns off? Probably blows a fuse or RCD. We’ll tell you why the circuit breaker knocks out when you turn on the washing machine and what the cause of failure.
Fuse breaker in the switchboard, how to determine where the short circuit occurs. When the breaker in the fuse box constantly knocks out the breaker, what to do with this, how to determine the cause of the fault?
Tripping a circuit breaker can be caused by many things. This can be either an appliance malfunction or a short circuit in the wiring. You can determine the cause of tripping yourself.
A circuit breaker is a device designed to protect an electrical system from overloads and short circuits.
There are cases when you have to solve the problem of tripping. Causes of knockout circuit breaker can be different, and they need to know in order to prevent breakdowns of household appliances or electrical wiring fire.
Features of the structure of the electrical distribution board
All protective and distribution equipment is placed in special panels. Design features of the switchboard allow you to control the flow of energy and supply it evenly to all channels.
The electrical switchboard includes:
Other components may also be present, depending on the functionality of the panel.
The circuit breaker helps protect the wiring from negative consequences. The peculiarities of the switch operation are as follows:
- The main task is to protect the electrical wiring and the appliances connected to it from excessive current;
- installation should be made on the phase circuit, which is broken when the packer is disconnected;
- The circuit breaker can de-energize the network when shutting down manually and in case of an emergency.
If there is an emergency case, the breaker in the panel knocks out.
Why does the automatic breaker always blow out?
- Network overload;
- breakage of a device included in the circuit;
- Breakdown of a lighting fixture;
- Faulty circuit breaker;
- short circuit.
Overloading is a condition where the power of the appliances to be connected exceeds the rating for which the circuit breaker is designed.
To avoid such a case, you need to carefully select the outlet group, to which will be connected powerful household appliances.
Plugging in a broken electrical appliance can also lead to tripping. When the circuit breaker knocks out due to turning on a light fixture, the problem should be looked for in the lamp socket, the quality of the contact or the transformer of the LED chandelier. In most cases, tripping is caused by a short circuit.
The circuit breaker on the meter is triggered and shuts down without an unnecessary load
A short-circuit is one of the main causes of tripping. If there is a sudden power outage, you should not immediately try to connect the circuit breaker. First you need to check the cores, the stability of the socket contacts, no short circuit in the socket (for lighting fixtures). Then check the wiring with a tester, the faulty section should be replaced by an electrician. After checking these factors, you can now turn on the breaker.
Short circuits can also occur without human intervention. It is possible when the contacts of electrical devices overheat or burn out.
When replacement is needed
If the connected total load is within normal limits, and the short circuit was not detected by the tester, the cause of the failure may be a faulty circuit breaker or poor contact.
If the breaker periodically blows out, it is advised to replace it with a similarly rated device.
Tightening the contacts may also help.
Do not increase the rating of the circuit breaker, if it has been calculated correctly. If it is too high, the insulation on the wiring can melt.
Tripped in the apartment and does not turn on, what to do?
If there is no light in the house or outlets do not work, you need to go to the switchboard and check the circuit breakers. Generally, simply turn on the breaker with the handle up.
If the power grid is overloaded by high-powered appliances, properly distribute them to other outlet groups. If you have a lot of extra lights in the house, it is advisable to install a separate automatic circuit breaker for them.
Check the quality of the contact all the way from the input to the circuit breaker to the lamps and outlets. Weak contacts should be re-tensioned.
For the circuit breaker to work properly, it is important to regulate the total wattage of appliances to be connected. Powerful appliances can be equipped with an additional disconnect device.
The circuit breaker should be chosen correctly, not exceeding the ratings. It is also important to monitor the temperature of the room in which the switchboard is installed. if overheated, the automatic unit can trip even on a small load.
Tripping a fuse box is a common problem in homes. Automatic disconnection can be triggered for both high currents and short circuits. Less common causes are high temperatures and malfunction of the device itself.
Why does the machine kick out when you turn it on or while washing??
For normal operation of the washing machine and to protect the user from electric shock, a protective circuit breaker is installed in the switchboard. If there is a leakage current RCD will go into protection and cut off power to the circuit. How to determine the cause of tripping of the circuit breaker? Here are a few basic symptoms and causes:
- RCD trips after the machine is plugged in. problem with wiring or outlet.
- Trips after starting the program. faulty control board or power button.
- Disconnects after washing start. motor, motor winding or control board is defective.
- Blows out after heating element starts. heating element is damaged.
- Turning off when wringing. water leaks into the interior of the machine.
To prevent tripping of the RCD it is necessary to detect a fault and eliminate it.
Leakage through wet contacts and insulation
A common cause of protection tripping is poor insulation in the power cord or plug. In modern devices, these parts are made in one piece at the factory and cannot be disassembled to check them.
This requires a megohmmeter or a tester. Use these devices to measure the insulation resistance between the pins of the plug and the grounding contact. It should not be less than 1 MOhm.
In the same way you can check the serviceability of the cable from the switchboard to the socket. This requires:
- 1. to disconnect the power supply;
- 2. Unplug the washer-dryer and other appliances from the socket;
- 3. Disconnect the wires coming from the RCD;
- 4. Measure the resistance between these wires and between each wire and the ground bus.
Another reason why the RCD trips when the washing machine is turned on could be a water or condensate leak inside the appliance. Water is a conductor and its presence in the wrong place can lead to leakage current and tripping protection.
The presence of moisture is determined by visual inspection. It must be performed immediately after the emergency shutdown of the machine, otherwise the wet parts may have time to dry. Therefore, before such an inspection, if necessary, the machine should be moved to a place convenient for inspection.
Naturally, if water leaks from under the machine, it can immediately be disassembled and search for places of its leakage.
|Important! Water inside the washing machine can lead to a short circuit and failure of the electronics.|
If leaks are detected they must be repaired, if there is condensation the board can be wrapped in cellophane and the connections covered with grease or silicone sealant.
Causes of the washing machine blowing a fuse when it is switched on
Just a minute ago, the washing machine was working as usual, but suddenly the lights went out suddenly, the drum stopped scrolling the laundry, and there was silence. In addition, the electricity in the apartment is also turned off. What happened? And most importantly, how to fix the breakdown? Most likely, it just blew a fuse. This happens when several appliances are running simultaneously, or one of them is so powerful that the power grid can not cope with the load. And now how to wash, if the culprit of the situation is the machine? And is there any way to make it so that it does not affect the plugs so much?
Let’s check the power grid
The machine when switching on and working has a heavy load on the electric network. The manufacturers of home appliances, including Bosch, warn about the “electric load” of washing machines and prescribe certain requirements for their use. Among them there is a need for a separate branch protected by RCDs and fuse disconnectors. Also recommended and the type of wires: VVG cable section in 3×2,5. In this case, it does not matter what washing model is purchased, compact, full-size, with dryer or not.
In reality, users do not observe safety precautions. often connected to a washing machine in a common socket with other household appliances, through an extension cord or “T-branch. All this leads to overheating and damage to wires, after which the socket melts, trips the RCD and the light turns off. It is easy to suspect something is wrong: the insulation on the wires is dark, the plastic is melted, and you can hear the smell of burning.
Avoid overloading the network and subsequent problems can be if:
- Allocate a separate branch under the washing machine;
- Evaluate the quality of the wiring;
- insert a moisture-proof socket (has a special cover);
- Include in the circuit RCD.
To connect the washing machine in the network through an extension cord or adapter is strongly not recommended. it is dangerous!
If there are no visible signs of overheating and damage to wires and sockets, then you need to check the power cord from the inside. Unscrew the screws that hold the back panel, remove it, and then remove the cable itself. After that use multimeter to “test” the cores for breakdowns. Immediately assess the state of terminals and contacts. Defective parts must be replaced.
Electrical wiring problems
The machine creates a fairly heavy load on the network when switching on and running, so it is necessary to use a separate network, protected by RCD and difacutomats. There are also special requirements for the wiring of such a network. It is necessary to use VVG cable 3×2,5, no matter what kind of machine you will need to connect with or without the drying function.

In fact, the automatic washer can be connected as desired: in a common socket with all kitchen appliances, through an extension cord, and sometimes even through an adapter. It leads to overheating and damage of electric wiring, power cord and melting of the socket body, after which the protection is triggered and the network is de-energized. Determine the problem with electrical wiring in some cases is not difficult, you can see the darkened wiring, melted socket, you can smell the burning insulation and plastic.
To prevent the problem from repeating it is necessary:
- Lay a separate network that supplies the washing machine according to the diagrams below or adequate alternative schemes
- use a socket with a moisture-proof housing;
- Use a mains protector.
Please note! Under no circumstances should the automatic washing machine be connected through an extension cord, adapter and other similar devices. Only a dedicated socket and only a direct connection through the power cord.
The integrity of the power cord can be checked with a multimeter. To do this, you need to dismantle the bottom panel of the washing machine automatic, unscrew the fixing bolts and remove the mains cable. After that you can test the wire strands to determine if there is a breakdown. The wire may be fine, but the terminals are burned, in which case they must be replaced.
Problems with the surge protector and button contacts
If you have tested the power cord and are sure that it works, then the problem may be in the surge protector. The device referred to as the surge protector is the part to which the power cord is connected. In some cases, the manufacturers of automatic washing machines combine the power cord with a “barrel” of the surge protector, so you have to change the two elements at once. The filter is an unrepairable part, so if you test it with a multimeter and examine it visually and find a malfunction, you must prepare to replace this element.
In rare cases, the automatic device knocks out due to poor connection between the wire and the network filter. This causes the contacts of the filter and the power cord to be burnt, respectively. In this case you should not try to clean the contacts, they must be replaced along with the surge protector, otherwise it may cause new surges and overloading in the network.
The RCD can blow out and because of a faulty button or a faulty control panel button. Why it happens? The main problem is that the contacts of the buttons wear out over time, when you press a faulty button, the contact breaks through and overloading occurs from this. What you need to do?
Removing the control box.
- Use a maltimeter to test the on/off button on the washing machine.
- Using multimeter, check the contacts of other buttons and wires going to them.
Pay Attention! Most often the plugs or the dispenser knocks out due to a faulty on/off button, so in order not to dig through the whole control panel in vain, start there.
The washing machine blows the plugs
Unexpected failure in the washing machine and turning off the light in the apartment is most often due to knocked out plugs. Your washing machine blows the plugs due to internal faults or other causes. The reasons independent of the machine can include:
- A newly purchased appliance has been started. If there is a problem with knocked out plugs, you should suspect a fault in the electrical wiring or improperly selected equipment to protect the power grid.
- Several appliances are working in the apartment at the same time. A kettle on, an electric stove and a washing machine running at the same time can provoke a knockout due to too much load on the electric network.
- The cord in the appliance is damaged, the fault is visible to the naked eye. If the plug or cord is “shorted,” it is advisable to refuse to use the equipment until the problem is corrected.
If the plugs blow for other reasons, the problem lies in the breakdown of the machine. It is desirable to immediately disconnect the device from the electric network, further use of a faulty unit is dangerous both for people living in the apartment and for the electric network of the whole house.
Electrical outlets can be damaged by cracks or overheating. Do not delay in repairing damaged outlets; they are potentially life-threatening, and repairing them is not a difficult or expensive task. Provided that you know at least a little bit about electrical engineering, this is a fairly simple job.
- Turn off the electricity in the apartment at the switchboard.
- Remove the bolt, remove the plastic panel. Make sure that all your connections are neatly inserted into the correct terminals and securely fastened.
- Press the front panel up against the back of the case. Make sure that the cables are not twisted and sit neatly inside the box so that they do not get pinched when you screw the faceplate on.
- Align the faceplate and secure it with the mounting screws. Make sure the front panel is aligned when tightening the screws.
- Place the level on top, alternately tightening the screws if you don’t have a good “eye” to check the level.
