The capacitor, or interference filter, filters out interference coming from the mains socket, interference from other appliances or interference from the washing machine.
It may be responsible for a breakdown in a washing machine that does not start, for example. If the appliance’s power cord and plug are functional, the capacitor, or noise filter, should be tested with a multimeter.
It is necessary to measure 230 volts at the input (two blue and brown wires) and at the output of the noise capacitor (here two white and black wires).
The suppressor is located just after the power cord, at the rear of the washing machine.
The anti-parasite capacitor, also known as the interference suppressor or noise filter, is an important component in a washing machine that helps reduce electrical interference and noise during operation. Over time, the capacitor can become faulty or fail, leading to electrical issues or disruptions. If you suspect that the anti-parasite capacitor in your washing machine is malfunctioning, it is important to test and potentially replace it. Testing and changing the anti-parasite capacitor require some technical knowledge and the use of appropriate tools. In this guide, we will walk you through the steps to test and change the anti-parasite capacitor of a washing machine.
Safety Precautions
Before starting any repair work on your washing machine, it is important to prioritize safety. Always unplug the machine from the power source before attempting any repairs. Additionally, ensure you are working in a well-lit area and wear protective gloves to prevent injury. If you are unsure or uncomfortable working with electrical components, it is best to seek professional help.
Tools Required
To test and change the anti-parasite capacitor of a washing machine, you will need the following tools:
- Screwdriver set (Phillips or Torx, depending on your machine)
- Multimeter
- Towels or rags (to protect the floor and clean up any spills)
Testing the Anti-Parasite Capacitor
Follow these steps to test the anti-parasite capacitor in your washing machine:
Step 1: Unplug the Washing Machine
Ensure the washing machine is disconnected from the power source by unplugging it from the wall socket.
Step 2: Locate the Anti-Parasite Capacitor
The anti-parasite capacitor is typically located near the main control board or power supply in the washing machine. Refer to your washing machine’s user manual or search online for specific information about the location of the anti-parasite capacitor in your particular model.
Step 3: Access the Anti-Parasite Capacitor
Remove any covers or panels that obstruct access to the anti-parasite capacitor. This may involve removing the back panel or a portion of the machine’s casing. Take caution and follow safety guidelines while removing components to prevent damage or injury.
Step 4: Identify the Capacitor Connections
Once you have access to the anti-parasite capacitor, identify the terminals or connections. It will typically have two wires or terminals connected to it.
Step 5: Set the Multimeter
Set your multimeter to measure capacitance. Ensure the range is appropriate for the expected capacitance value of the anti-parasite capacitor.
Step 6: Test the Anti-Parasite Capacitor
With the multimeter connected to the capacitor terminals, touch the probes to the corresponding terminals. Observe the multimeter reading, which should indicate the capacitance value of the capacitor. Consult your washing machine’s user manual or search online for the expected capacitance range for the anti-parasite capacitor in your particular model. If the capacitance reading is significantly different from the specified range or if it shows an open circuit, it indicates a faulty anti-parasite capacitor that needs to be replaced.
Changing the Anti-Parasite Capacitor
Follow these steps to change the anti-parasite capacitor in your washing machine:
Step 1: Unplug the Washing Machine
Ensure the washing machine is disconnected from the power source by unplugging it from the wall socket.
Step 2: Access the Anti-Parasite Capacitor
Remove any covers or panels that obstruct access to the anti-parasite capacitor, following the same steps as in the testing process.
Step 3: Disconnect the Electrical Connections
Carefully disconnect the wires connected to the anti-parasite capacitor. Take note of their positions or use a marker to label them for proper reconnection later.
Step 4: Remove the Faulty Anti-Parasite Capacitor
Using a screwdriver, remove any screws or fasteners that secure the faulty anti-parasite capacitor in place. Carefully detach it from its mounting location.
Step 5: Install the New Anti-Parasite Capacitor
Take the new anti-parasite capacitor and position it in place of the old one. Ensure it is aligned correctly and fits snugly. Insert and tighten the screws or fasteners to secure the new anti-parasite capacitor in place.
Step 6: Reconnect the Electrical Connections
Reconnect the wires to the new anti-parasite capacitor, ensuring they are properly positioned and securely attached. Refer to the labels or notes made during the disconnection process.
Step 7: Reassemble the Washing Machine
Once you have completed the anti-parasite capacitor replacement, reassemble any covers or panels you removed earlier to access the anti-parasite capacitor. Use the appropriate screws or fasteners to secure these components back in place.
If you encounter any persistent problems or suspect a fault with the anti-parasite capacitor despite the replacement, it is recommended to consult a professional appliance repair technician or contact the manufacturer for further assistance.
In conclusion, testing and changing the anti-parasite capacitor of a washing machine is a task that requires some technical knowledge and attention to detail. By following these steps and using the appropriate tools, you can successfully diagnose a faulty anti-parasite capacitor and replace it to restore proper functionality to your washing machine. Always refer to your washing machine’s user manual for specific instructions and guidelines, as different models may have slight variations in the anti-parasite capacitor testing and replacement process. Regular maintenance and prompt anti-parasite capacitor replacement will help ensure the optimal performance of your washing machine and minimize electrical interference during operation.
