③ Disconnect the control panel cable (need to take photos and records)
Step 3: Take out the pulsator plate
• Pry open the central decorative cover (pay attention to the buckle direction)
• Loosen the fixing nut counterclockwise (anti-slip treatment required)
• If the rust is dead, spray WD-40 and let it sit for 15 minutes.
• Use a rubber hammer to symmetrically tap the edge of the impeller until it becomes loose.
