General fit guidance (AU / NZ)

• If you remove the agitator cap and see a wing-nut, this 425059 part is correct.
• If you see a hex-head bolt/screw, your machine likely needs 420665 (post-2005 design).

Product Details

• Genuine Fisher & Paykel spare part in original packaging.
• Durable plastic wing-nut design resists corrosion; engineered for the SmartDrive system.
• Restores firm agitator attachment for proper wash action and cleaning performance.
• Colour: White. Hardware/cap not included (reuses existing).

What this part does

The 425059 fastener locks the agitator (centre post) to the washer’s drive mechanism. A worn or missing bolt allows the agitator to loosen, causing poor agitation and sub-par wash results. Replacing it returns the tub to smooth, reliable agitation.

Where it sits / related parts

• Located beneath the agitator cap or softener dispenser at the top of the agitator.
• Works with the agitator assembly and drive shaft. Compare appearance to confirm: wing-nut (this part) vs hex-bolt (420665, 2005+).
• Agitator cap and other components sold separately.

Common symptoms of a worn / missing bolt

• Loose or wobbly agitator; rattling during wash.
• Clothes not moving properly; poor cleaning performance.
• Agitator lifts off easily when cap is removed.

Installation (Overview)

1. Unplug the washer.
2. Remove the agitator cap/softener dispenser to expose the fastener.
3. Unscrew and remove the old wing-nut; lift agitator if needed to inspect splines.
4. Thread on the new 425059 by hand; tighten snugly (do not over-tighten).
5. Refit the cap and run a short cycle to confirm proper agitation.

FAQ

Is this genuine?

Yes — we supply a genuine Fisher & Paykel part in original packaging.

What’s the difference between 425059 and 420665?

425059 is the older wing-nut design used on pre-2005 models. 420665 is a hex-head bolt used on most 2005 and newer models. They are not interchangeable. Check under your agitator cap to confirm which style you have.

How do I confirm fit without the serial plate?

Remove the agitator cap. If you see a white wing-nut, choose 425059. If you see a metal hex-bolt, choose 420665.

Do I need special tools?

No special tools for the 425059 wing-nut — hand-tighten until snug. Do not overtighten.

Will this fit GWL10 / GWL11 / GWL12 / IWL12?

Yes, these popular pre-2005 models commonly use 425059. Always visually confirm the wing-nut style under the cap.

Does this come with the agitator cap?

No — the cap/softener dispenser is not included and is typically reused.

What if my agitator is still loose after replacement?

Verify the bolt is seated and snug. Inspect the agitator splines for wear or cracks and replace the agitator if damaged.
