The washing machine does not start and the indicators do not light up

When the washing machine does not turn on and the indicators do not light up, many people think that the device is badly damaged and only a competent technician can fix it. But the cause of the breakdown is not always so serious. Sometimes it’s a simple problem that you can fix yourself. Let's figure out why the machine may not start, where to start diagnostics?

What could have broken?

At any moment, a washing machine that was functioning properly just yesterday may stop working. In such a situation, when you connect the machine to the outlet and press the power button, nothing happens - the device does not emit a sound signal, the LEDs on the control panel remain extinguished. The reasons for this “behavior” of the equipment may be the following:

• malfunction of the socket where the power cord is connected;
• damage to the cord plug;
• power outage in a house or apartment;
• failure of the noise filter;
• power cord defect;
• sticking or damage to the “On” button;
• control module malfunction;
• Broken wiring inside the washing machine.

Therefore, before calling a technician, you should find out the probable cause of the problem. A burnt-out cord, its plug, or a damaged power filter can easily be replaced yourself. The start button is also easy to repair. Let's figure out where to start diagnosing.

Let's pay attention to electrical communications

A trivial situation is when the machine does not turn on because there is no electricity supply. It often happens that the housewife has planned a wash, tries to start the machine, but the equipment shows no signs of “life.”Check if there is light in the apartment - click the nearest switch. Perhaps there is no power in the whole house, or it is on your panel that the plugs have been knocked out.

Another problem that can cause a problem is a faulty outlet. If it is old, the contacts may have burned out. It’s easy to check the power point - connect any other electrical appliance to it: hair dryer, kettle, lamp. If small household appliances do not want to work, then the problem really is in the outlet.

What to do if there is light in the apartment and the socket is working? This means the problem is in the washing machine itself. The test should be performed from simple to complex. First, inspect the power cord and its plug - if they have a burning smell or there are other defects, you will have to replace the components.

Power surges in the network can cause the washing machine to not turn on and the indicators to not light up.

It is voltage surges that can cause a fire in the power cord or damage to its plug. The cord is checked using a multimeter. The tester calls all the conductors inside the insulation.

Next in line for testing is the surge protector. It is this that protects the washing machine from various interferences and takes the brunt of it - it absorbs voltage surges in the network, protecting the electronic microcircuits that are stuffed into a modern automatic machine. When the capacitor burns out, power is not supplied to the main modules of the SMA, so the equipment does not turn on.

You can check and, if necessary, replace the surge protector yourself. The algorithm of actions will be as follows:

• Turn off the power to the automatic machine, turn off the tap on the water pipe;
• move the machine away from the wall to have access to the back of the case;
• Unscrew the 2 screws holding the top panel of the washing machine;
• remove the cover of the machine to the side;
• find the noise suppression filter - it is located at the point where the power cord exits the washing machine;
• disconnect the wiring from the capacitor and remove it from the machine;
• set the multimeter to buzzer mode;
• check the filter for breakdown;
• if there is no breakdown, check the FPS resistance.

If the resistance produced by the surge protector is 0 or 1, then the part is burnt out and needs to be replaced.

To choose the right capacitor, it is better to show the store manager the original, burnt part. Then the specialist will offer you a complete analogue. When this is not possible, tell the seller the model and serial number of the automatic machine. Installing a new filter is very simple - fix it with bolts in its original place and reconnect the previously reset wiring. Next, the body is assembled and the machine is checked. If the capacitor was faulty, then after replacement the washing machine should work.

Power button does not respond

Sometimes the machine refuses to turn on precisely because the power button is damaged or stuck. Often the contacts simply oxidize and it stops responding to pressure. This assumption is checked immediately after diagnosing the power cord and interference filter.

To remove the button, you will have to remove the cover of the machine body. Next, the wires are pulled off the key; it is better to photograph the connection diagram - this will help when reinstalling the part. Then you need to pry the latches and pull out the button.

First, the removed button is probed with a multimeter. Then the resistance it produces is checked. If a problem is identified, the part will have to be replaced.Sometimes the problem can be solved by cleaning the contacts, so technicians recommend trying this option. Even if after this the key does not ring, you will have to replace it.

The chip burned out

The reason that the washing machine does not turn on may be a damaged microcircuit on the control board. The electronic module of an automatic machine consists of many semiconductors, and it will be difficult for a non-specialist to understand which element has failed. Therefore, it is better to entrust the diagnostics of the microprocessor to a specialist.

Sometimes there are visible signs of damage on the control board, so you can inspect it yourself. To do this you need:

• turn off the power to the machine;
• pull out the powder receptacle;
• Unscrew the screws holding the control panel;
• remove the tidy;
• deal with the latches and disassemble the panel;
• take out the control board.

When disassembling the dashboard, try not to touch the wires so as not to accidentally break them.

After completing disassembly, inspect the control board. If there are no visible damages, most likely we are talking about hidden defects that only a specialist can detect. It is better to transfer the module to a service center for diagnostics and further repairs.
