Quick answer: The most common cause of a Fisher & Paykel WH7560 / WH8560 or Haier HWF75 / HWF85 front loader that will not lock its door is wear between the door latch hook and the door interlock switch. Once the hook no longer seats squarely in the interlock, the machine treats the door as open: the door light flashes or a door fault code appears and the cycle will not start. Replacing the hook and the interlock together is a 20–30 minute screwdriver job. Here is how to confirm the fault before buying anything.

Why one guide covers two brands
Fisher & Paykel’s WH7560 / WH8560 front loaders and Haier’s HWF75 / HWF85 range share a manufacturing platform, and the door hardware shows it. One washing machine door hinge is documented for 85 models across both Fisher & Paykel and Haier — the two brands share manufacturing platforms. The door latch hook is the same part number on both badges, and the interlock switch differs only by its suffix letter. So we bundle the two parts as a pair of closely related kits, one per badge. Pick by the badge on the front panel, then confirm the model number on the model sticker inside the door opening.
Which kit matches your model
Each kit contains one door interlock switch and one door latch hook. The Fisher & Paykel kit and the Haier kit each pair their own interlock variant with the same door latch hook. Both are priced below buying the two parts separately. Find your model number in the table, then open the matching kit.

 Fisher & Paykel | WH7560J1, WH7560J2, WH7560P1, WH7560P2, WH8060P1, WH8060P2, WH8560J1, WH8560J2, WH8560P1, WH8560P2, WH9060J3, WD7560P1, HWF85DW1, 92229-A, 92230-A, 92231-A, 93161-A, 93229-A, 93230-A | Fisher & Paykel door lock & latch hook kit |
 Haier | HWF75AW1, HWF75AW2, HWF75DW1, HWF80BW1, HWF80BW2, HWF85AW1, HWF85BW1, HWF90BW1, HWM75-B12266, HWM85-B14266, WH7560P1 | Haier door lock & latch hook kit |
One model, the WH7560P1, appears on both lists because the platform is shared; for a Fisher & Paykel-badged WH7560P1 the Fisher & Paykel kit is the natural choice. If your model number is on neither list, send it to us and we’ll check before you order — we are on Sydney’s Northern Beaches and answer quickly. Both kits sit in our Repair Kits category.
Symptoms that point to the hook and interlock
- Door light flashing and no start (Fisher & Paykel). You press Start, the door indicator flashes and nothing else happens: the controller has not received the door-closed signal.
- Door fault code (Haier). Haier machines on this platform report the same condition as an error code. Our Haier E8 door lock fault guide covers the code side in detail.
- The door has to be slammed, lifted or pushed at one corner before the machine will start. Classic hook wear — the hook is entering the slot at an angle.
- Cycle starts, then stops within a minute with the door light or code. Intermittent interlock contact.
- Door will not release at the end of the cycle. Can be the interlock, but rule out the simpler causes first (further down).
- Visible damage. A hook that rocks, a chipped or rounded tip, or an interlock slot with a chewed mouth.
Confirm the fault before you buy
- Unplug the machine, turn off both taps and open the door fully.
- Grip the hook on the edge of the door and try to rock it — it should be firm. Check the tip for wear and the plastic around its screws for cracks.
- Look at the interlock slot in the front of the door opening for a cracked or opened-up mouth, or debris inside.
- Close the door slowly by hand; the hook should slide into the slot with a positive click. If you have to lift the door to line it up, the hinge may be tired too.
- Plug back in, select a cycle and press Start. A healthy interlock gives a distinct click within a few seconds. Door light or code with no click points at the interlock; a click followed by a door fault points at a hook that is not holding the switch fully closed.
- Check the door seal band. A seal that has slipped its band can hold the door off its seat just enough to stop the lock engaging.
Why replace both parts at once
The hook and the interlock wear against each other: every cycle the hook drives into the slot and the lock mechanism bears on the hook, so the wear is shared. Fit a new interlock behind a worn hook and the fresh switch is held by a rounded-off tip — the door fault is often back within a month. Fit a new hook into a chewed interlock and it seats in the wrong spot. Both come out with the same screwdriver in the same 20–30 minutes, which is why the pair is sold as a kit priced below the two parts bought separately.
Pros: both wear surfaces renewed at once, one job instead of two, parts matched to the models listed. Cons: on a nearly new machine where only the interlock has failed electrically, you are replacing a hook with life left in it; each component is available on its own — the Fisher & Paykel door interlock switch, the Fisher & Paykel door latch hook, the Haier door interlock and the Haier door latch hook. For a machine slammed shut for years, the Fisher & Paykel kit or Haier kit is the safer buy.
How to fit the kit: step by step (20–30 minutes)
You need a Phillips screwdriver, a small flat blade and a torch. The front panel stays on.
- Unplug the machine and turn off the hot and cold taps. The interlock carries mains voltage.
- Free the door seal around the interlock. The outer lip of the seal is held to the cabinet by a spring band or wire clip. Ease it back with the flat blade over the section nearest the interlock only.
- Remove the interlock. Take out the screws holding it to the front panel, reach in behind the panel and draw it out through the door opening, wiring attached.
- Swap the wiring. Photograph the connector, unclip it and plug it into the new interlock until it clicks fully home — a half-seated plug is a common reason a new interlock “doesn’t work”.
- Fit the new interlock, then work the seal lip and its band back into place all the way round.
- Replace the hook. Remove the screws holding it to the inner frame of the door (on some doors you lift the inner trim to reach them), fit the new hook and tighten. If the plastic around the screw holes is cracked, the door assembly itself needs attention.
- Test. Close the door by hand: it should latch with a positive click, no lifting or slamming. Reconnect power, run a rinse-and-spin, listen for the lock click and check the door releases at the end.
When it is not the lock
- Water still in the drum. The interlock will not release while the drum holds water. Run a drain or spin cycle first.
- Normal release delay. Front loaders keep the door locked for a couple of minutes after the cycle ends.
- Loose harness plug. Reseating a plug that has worked loose behind the panel costs nothing.
- Hinge sag. A dropped door enters the slot low; a new hook helps, but a worn hinge keeps loading it unevenly.
- Controller side. If a new interlock and hook click properly and the door fault remains, the next suspect is the control board or harness — a job for a repairer.

Frequently asked questions
My Fisher & Paykel WH8560P1’s door light is flashing and it won’t start. Is it the interlock or the hook?
Usually both. If the hook rocks or the door needs lifting to latch, the hook is worn; if the door latches cleanly but you never hear the lock click, the interlock is the weaker link. Because they wear together, the Fisher & Paykel door lock and latch kit covers both in one 20–30 minute job.
What is the difference between the Fisher & Paykel and Haier kit interlocks?
They are the same family of door interlock switch with different suffix letters — one suffix ships in the Fisher & Paykel kit, another in the Haier kit. The door latch hook is common to both. Go by each kit’s model list and your model sticker; if your model is on neither list, send us the number and we’ll check.
I have a Haier HWF75AN1 or HWF85AN1. Does the Haier kit fit?
The AN1 models are not on the Haier kit’s list. Those machines use a different interlock variant, listed separately as the Haier door interlock switch for HWF75AN1, HWF85AN1, HWF80AN1, HWF09AN1 and HWF10ANB1. Confirm your model number on the model sticker before ordering either.
My Haier HWF85AW1 shows a door error code. Is that the same fault?
A door fault code means the controller has not seen the door-closed signal — the same condition Fisher & Paykel machines show as a flashing door light. Work through the checks above; if the hook or interlock is worn, the Haier door lock and latch kit matches the HWF85AW1. Our E8 guide covers clearing the code once the parts are fitted.
The door won’t open at the end of the cycle. Do I need the same parts?
Not always. Run a drain or spin to clear any water, then wait a couple of minutes for the normal release delay. If the door still will not release with an empty drum, the interlock is the likely cause and the kit is the fix.
