The washing machine is a very often used device, which can cause breakdowns after a while. Sometimes the washing machine does not stop spinning at the end of a wash cycle. There are several checks and tests you can perform to fix this problem and repair the fault:
- Check the water supply
- Check the solenoid valve filter
- Test the solenoid valve
- Check the hoses
- Clean the detergent drawer
- Test the solenoid valve power supply
- Check the washing machine pressure switch
- Check the continuity of the wiring
If the fault persists after having checked all these elements, it will probably be necessary to replace the electronic card.
Discovering that your washing machine won’t stop can be a frustrating and concerning situation. A washing machine is designed to complete its cycles and automatically stop once the process is finished. However, there are several potential reasons why a washing machine may continue to run, ranging from simple issues to more complex electrical or mechanical 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 stop and provide possible solutions to address the issue.
1. Stuck or Faulty Timer/Program Control
The timer or program control is responsible for regulating the different cycles and durations of the washing machine. If the timer gets stuck or malfunctions, it can cause the machine to continue running indefinitely. Check the timer or program control settings to ensure they are not set to an extended or continuous cycle. If the problem persists, a faulty timer or program control may need to be replaced by a professional technician.
2. Faulty Water Inlet Valve
The water inlet valve controls the water flow into the washing machine during the wash and rinse cycles. If the valve is stuck open or has a malfunction, it can cause the machine to continuously fill with water and not progress to the next cycle. Inspect the water inlet valve and ensure it is functioning properly. If necessary, replace the faulty water inlet valve to resolve the issue.
3. Defective Pressure Switch
The pressure switch, also known as the water level switch, monitors the water level inside the washing machine. It signals the machine to stop filling with water once the desired level is reached. If the pressure switch is faulty or misaligned, it may not accurately detect the water level, causing the machine to continuously fill or drain. Test the pressure switch for continuity and proper operation. If it is defective, consider replacing it to restore normal operation.
4. Blocked or Defective Drain Pump
A blocked or defective drain pump can prevent the washing machine from properly draining the water after each cycle. If the machine doesn’t detect the drain process completion, it may continue to run to remove excess water. Check the drain pump for any blockages or debris that may be hindering its operation. If necessary, clean the pump or replace it if it is defective.
5. Electrical Control Board Issues
Electrical control board malfunctions can disrupt the proper functioning of the washing machine. If the control board gets damaged or experiences a fault, it may cause the machine to operate continuously or exhibit erratic behavior. Inspect the control board for any signs of damage or burnt components. If required, contact a professional technician to diagnose and repair or replace the faulty control board.
CHECK THE WASHING MACHINE PRESSURE SWITCH
To check the correct operation of the pressure switch:
- Remove the hose where the air comes from
- Blow inside the pressure switch: you should be able to hear a “click” from the ball or the membrane.
- Replace it if you can’t hear anything or need to blow hard to hear the noise.
Please note that analog pressure switches, made up of an electronic card, cannot be controlled in this way. This test works with ball pressure switches, or so-called “membrane contact” and “ball contact”.
CHECK THE WIRE CONTINUITY OF THE WASHING MACHINE
Now proceed to check the continuity of the wiring of the pressure switch and that of the solenoid valve.
- Unplug the washing machine.
- Set your multimeter to continuity mode (represented by a waveform) or to the smallest range of ohmmeter mode.
- Put one tip of the multimeter on the terminal of your pressure switch and the second tip on the opposite of the same wire located on the electronic board. You can spot your yarn by its color or by following it visually.
- The multimeter should emit a “beep” or display a value. Otherwise, your wire is cut, it will then have to be repaired or replaced.
- Put one tip of the multimeter on the terminal of your solenoid valve and the second tip on the opposite of the same wire located on the electronic board.
Carry out this continuity test for all the wires between each of these two parts and the electronic board.
Here are some troubleshooting steps you can take when your washing machine won’t stop:
- Check the timer or program control settings to ensure they are not set to an extended or continuous cycle.
- Inspect the water inlet valve for any malfunction and replace it if necessary.
- Test the pressure switch for continuity and proper operation. Replace it if it is faulty.
- Check the drain pump for blockages and clean or replace it if needed.
- Inspect the electrical control board for any damage or faults. Contact a professional technician for repair or replacement.
By following these steps, you can often identify and address the issue of a washing machine that won’t stop. Regular maintenance, proper usage, and attention to the machine’s components will help prevent future occurrences.
In conclusion, a washing machine that fails to stop can be caused by various factors, including a stuck or faulty timer/program control, a faulty water inlet valve, a defective pressure switch, a blocked or defective drain pump, or electrical control board issues. 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.
