DIY Series 67: How to Remove Jammed Washing Machine Pulsator

Panasonic Washing Machine (NA-F70S7) pulsator was stuck / jammed due to accumulated dirt and rusted. However, the drum was dirty, and it needs a cleaning service.

Many approaches had been found online and I had tried most of them but yet still failed to dismantle the pulsator (and its bush!) from the washing machine. 

Example:

  • Use a string to pull out the pulsator
  • Use special tools to remove the pulsator
  • Use heat gun to heat up the pulsator's bush (if you managed to unscrew and removed the pulsator)

Finally, I decided to use my own way, with replacement needed for pulsator and mechanism gear unit.
