How to change the noise filter in the washing machine

Every year, manufacturers are increasingly improving washing machines - there is a struggle for the quality of parts and assembly. But even despite the high-quality components, the washers break down - often due to sudden voltage drops in the network.

Power surges could instantly disable the control board and all electronic components, if no noise filter was provided to protect them.

  • 1 Why a washing machine needs a noise filter
  • 2 Principle of operation
    • 2.1 Types of capacitors
    • 2.2 Replacement sequence
  • 3 How to verify a noise suppression capacitor

Using a washing machine;The wider the functionality and the greater the choice of programs, the more sensitive the control, the more dangerous the voltage drops for them. High probability that they will lead to the combustion of one of the elements.

Initially affected:

  • main board;
  • electric motor;
  • heating element( TEH);
  • wiring.

If you want to avoid costly repairs, do not neglect the timely replacement of the network noise filter for the washing machine.

In addition, the surge protector protects other equipment from high-frequency currents that may occur during operation of the AGR.

principle of operation Standardly passes through itself oscillations with a frequency of 50 GHz. Anything lower or higher than this value blocks the part. However, protection may not withstand too high voltage spikes.

In this case, the noise filter will need to be replaced.

A voltage stabilizer is recommended for better protection. It will help protect parts of the washing machine from damage.

Varieties of capacitors

The filter can be not only internal, but also external. Internal immediately installed during the production of the machine. External is an extension cord for 3-8 outlets. It is equipped with buttons that turn off the electricity to the equipment when the voltage drops.

Sequence of work on the replacement of

How to understand that the filter is broken? Externally, this may be manifested by the fact that the washing machine does not turn on, or when it is turned on, it knocks out a switch in the switchboard.

This is a dangerous breakdown that causes a short circuit and a fire. Therefore, first disconnect the device from the network.

How to check the interference suppression capacitor

This is done using a multimeter tester.

To get to the condenser, do the following:

  1. After disconnecting the washer from the network, unscrew the two screws at the back, remove the top cover.
  2. At the top of the side wall is a power filter.

Inspect the part: burned or burned parts of the wiring are usually visible when burning. Then it is already clear that it needs to be replaced.

What to do if there are no signs externally detected:

  • Set the multimeter to the resistance measurement position.
  • Connect its probes to the capacitor contacts.
  • Perform an input and output test.

The capacitor is faulty if there is no output voltage during the measurement.

How to change the power filter in the washing machine-machine? Proceed as follows:

  • On the back of the CMA, unscrew the two bolts securing the filter.
  • If you are not sure that you correctly remember the location of the capacitor wires, take a picture of them.

  • You can do even easier: take a new filter in your hand and alternately switch the connectors from the old to the new part.

If you do not know how to choose a new part, remove the broken capacitor and go with it to the store. The seller will give you a suitable item for your car.

This is an easy repair that even a beginner can handle. Organizing the correct protection for your equipment, you save on its further repair.
