Function & Importance of the Start Capacitor

The start capacitor provides a brief surge of electrical energy to the washer’s motor during startup. This extra boost is essential to:

  • Initiate motor rotation

  • Enable proper agitation and spin cycles

  • Ensure smooth and efficient washer startup

Without a functioning capacitor, the motor may struggle or fail to start entirely. This component essentially acts as the “kick-start” for your washer’s drive system.

Using a Genuine OEM capacitor like WP8572720 ensures:

  • Correct voltage and capacitance ratings

  • Safe electrical performance

  • Reduced risk of motor damage

Common Symptoms of a Faulty Start Capacitor

A failing start capacitor can cause several noticeable washer issues:

  • Washer won’t start at all

  • Humming or buzzing noise when attempting to start

  • Motor tries to start but shuts down quickly

  • Washer fills with water but does not agitate or spin

  • Intermittent or inconsistent startup behaviour

Will replacing this part fix your issue?
If your washer motor is not starting or only humming, a faulty start capacitor is one of the most common causes—and replacing it often restores normal operation.
