There are two types of washing machines: the top-loading washing machine, also called a top washing machine, and the front-loading washing machine. In both cases, a control panel allows you to choose the program according to the type of washing desired.
When the lights of a washing machine do not light up, it is not necessary to have access to the control panel to understand the origin of the breakdown. It will be necessary to check certain elements potentially responsible for this failure:
- the power cord
- the switch
- the electronic card
- the power board
Discovering that your washing machine won’t turn on can be a frustrating experience, especially when you have laundry to do. There are several potential reasons why a washing machine may fail to turn on, ranging from simple issues to more complex electrical problems. Understanding these causes can help you troubleshoot the problem and find a solution. In this article, we will explore the common reasons why a washing machine won’t turn on and provide possible solutions to address the issue.
1. Power Supply Issues
The first thing to check when your washing machine won’t turn on is the power supply. Ensure that the machine is plugged in properly and that the outlet is functioning. Try plugging another appliance into the same outlet to verify if it’s working. If there is no power, check the circuit breaker or fuse box and reset any tripped breakers or replace blown fuses.
2. Door or Lid Switch Problems
Most washing machines have a door or lid switch that prevents the machine from operating if the door or lid is not properly closed. If the switch is faulty or not engaging properly, it can prevent the machine from turning on. Make sure the door or lid is securely closed and check if the switch is damaged or malfunctioning. If needed, consult the manufacturer’s instructions or contact a professional technician to replace the switch.
3. Faulty Control Panel or Timer
A faulty control panel or timer can also prevent the washing machine from turning on. If the control panel doesn’t respond when you press the buttons or if the timer is not advancing, it may indicate a problem with these components. Inspect the control panel for any visible damage or signs of malfunctioning. If necessary, seek the assistance of a professional technician to diagnose and replace the faulty control panel or timer.
4. Tripped Overload Protector
Some washing machines have an overload protector that trips if the motor is overloaded. This safety feature prevents damage to the motor. If the machine is not turning on, it’s possible that the overload protector has tripped. Allow the machine to cool down for some time and try resetting the overload protector, usually located near the motor. Refer to the manufacturer’s instructions for the specific reset procedure.
5. Faulty Motor or Motor Control Board
If the power supply is fine, the door or lid switch is working correctly, and the control panel is functioning, it’s possible that the washing machine’s motor or motor control board is faulty. A malfunctioning motor or control board can prevent the machine from turning on. In such cases, it is recommended to contact a professional technician to diagnose and repair the motor or control board.
CHECK THE ELECTRONIC BOARD
If the power supply or the cord of your device does not pose a problem, it is necessary to check the electronic card. Washing machines are generally equipped with two electronic boards: the control board and the power board. In most cases, the power board is faulty.
It must be replaced if it is supplied with 230 Volts and your machine does not turn on. It is located behind the control panel.
- Set your multimeter to AC and select the larger gauge.
- Place the test probes of the multimeter on the terminals which supply the electronic card.
- If the current does not arrive on the electronic card, then the wiring will have to be replaced. If current is flowing, then the board is faulty and will need to be replaced.
TEST THE POWER BOARD
It is now necessary to check the electronic card. Washing machines are generally equipped with two electronic boards:
- A control board (with buttons and screen)
- A power card: it can be located in different places around the tank-drum assembly, but it can also be fixed or coupled to the control card.
It needs to be replaced if it is powered, but your machine does not turn on. To access the power board, the control panel must be removed.
- Reconnect your device. This test is carried out under voltage: wear insulating gloves and take care not to touch the metal parts.
- Locate the board’s power wires (often red, black, or white).
- Set your multimeter to 20 volts DC, then place the test probes on the voltage outputs of the board.
- If you cannot find a value between 5 and 12 volts, then the electronic card will have to be replaced.
Here are some troubleshooting steps you can take when your washing machine won’t turn on:
- Verify the power supply and ensure the machine is properly plugged in and the outlet is functioning.
- Check if the door or lid is securely closed and inspect the door or lid switch for any damage or malfunction.
- Inspect the control panel for any visible damage or malfunctioning buttons.
- Reset the overload protector if applicable.
- Contact a professional technician to diagnose and repair any motor or control board issues.
By following these steps, you can often identify and address the issue of a washing machine that won’t turn on. Regular maintenance, proper usage, and attention to electrical connections will help prevent future occurrences.
In conclusion, a washing machine that fails to turn on can be caused by various factors, including power supply issues, faulty door or lid switches, malfunctioning control panels or timers, tripped overload protectors, or faulty motors or motor control boards. By understanding these common causes and following the troubleshooting steps mentioned above, you can often identify and address the issue effectively. If the problem persists or if you are unsure about any repairs, it is advisable to consult a professional technician to diagnose and repair the specific problem with your washing machine.
