The washing machine will no longer switch on at all

You want to start your machine but nothing happens and no lights come on! A power supply issue is the first thing you should check, but not just that... This troubleshooting guide will help you find the reason for this breakdown.

THE POTENTIAL CAUSES FOR THIS ISSUE:

• There is a power supply issue

• The mechanical switch is damaged

• The start/stop switch is defective

• The noise filter is defective

• The main circuit board (PCB) is defective

• The control board is malfunctioning

WARNING
Before working on your appliance, be sure to disconnect it from the electrical power supply.
Risk of electric shock.

No power is being supplied to the washing machine

Start by checking using another device (a hair dryer for example) to see if there is indeed a current running through the plug. If there isn't one, check the mains electricity switchboard in your home or call an electrician. Also check the wall socket the machine is connected to. Sometimes one of the socket components may be melted or burnt out, stopping the power to the washing machine.

The on/off switch is damaged

On certain models of washing machine, there is still a mechanical on/off switch, like the switch you use to turn the lights on and off in your home. If this switch has melted or is no longer making contact properly, the appliance won't work. To get to it, you need to remove the top panel and the control panel strip to check the switch using a multimeter set to the ohms setting to see whether or not the contacts are still conducting current properly.

The electric on/off switch is defective

The electric switch that switches the appliance on connects with lugs or connectors. It may be defective due to the electric current (overheating) and can end up with a short circuit. In such cases, the switch may then trip the circuit breaker. Most of the time, the switch just doesn't work any more and the start button just remains stuck.

The noise filter is defective

The capacitor (also called a noise filter) is usually connected just after the electrical cable and is located inside the machine. It is used to remove the noise from the electrical network. It can happen that this condenser burns or gets damaged and no longer lets the electric current of 230 volts pass through it which prevents the circuit board (PCB) from getting any power. You can check this component using a multimeter. If you see a voltage of 230 volts at the condenser's input and output, this means that it is operational. If it isn't working however, you need to consider replacing it.p>

The main circuit board (PCB) is defective

The circuit board (PCB) or power module controls all of your washing machine's functions (the motor, the heating, the water, etc.). Check using a multimeter whether there is a voltage of 230 volts on the main module. If the answer is yes, you should then measure the voltage that comes out of the module and goes to the control board; it's usually less than 20 VDC. If you don't see any voltage at all, it means that the power board must be replaced.

The control or display board is malfunctioning

If you see that the control board's power supply voltage is between 5 and 20 Volts on its connector (coming from the power board) and it's not turning on, it's probably because the control board needs replacing.
