Quick answer: If your Haier TwinTasker is leaking from the front drum door, smells musty, or the boot is torn or mould-stained, the fix is a new door seal for the main front-load drum. The replacement seal costs $78.95, fits the HWX8040DWI TwinTasker, and takes about 45 to 60 minutes to fit yourself with basic hand tools. Unplug the machine first — the rest is patience with the retaining springs.

The TwinTasker is a dual-drum machine — this seal is for the front drum
The Haier TwinTasker is a two-drum design: an 8kg front-load drum below and a separate 4kg top-mount drum that lets you run two washes at once. The door seal covered here is the rubber boot for the main 8kg front-load drum — the one behind the round door on the front of the machine. The smaller top drum uses a different lid arrangement and is not sealed by this boot.
So when a TwinTasker leaks from the front door or grows mould around the front opening, this is the part you need.
What the door seal does
The door seal is the flexible rubber boot between the front drum opening and the glass door. During a cycle the wash water sits at the bottom of the drum, and the seal is the only thing holding it inside the machine. It presses against the door glass to make a watertight ring.
It works hard. The rubber flexes on every spin, holds hot detergent water, and its inner fold traps lint, hair and the occasional coin. Over years of use the boot perishes, splits along the fold, or grows black mould that won’t wash out. Once it tears or stiffens it stops sealing — and the machine leaks onto the floor.
Symptoms of a failed TwinTasker door seal
| Symptom | Likely cause |
|---|---|
| Water pooling at the front of the machine during wash or spin | Split or perished seal, or debris caught in the fold |
| Black or grey mould in the rubber folds that keeps returning | Mould has soaked into the rubber — clean first, replace if it persists |
| A visible tear, crack or hole in the boot | Seal has failed and needs replacing |
| Musty smell from the front drum | Trapped water and mould in the seal fold |
| Coins or clips slipping past the seal | Boot no longer sitting flush against the door glass |
If the rubber is torn or the mould won’t shift, the seal is finished. A clean is worth trying first for a mould-only problem, but a torn boot only worsens.
How to replace a Haier TwinTasker door seal step by step
Safety: mains voltage — always unplug at the wall before opening the cabinet.
- Unplug the machine and turn off the water taps. Keep a towel and shallow tray handy; the seal fold holds trapped water.
- Open the front door and locate the outer retaining spring. The boot’s outer lip is held to the front panel by a spring band seated in a groove around the door opening.
- Release the outer spring. Find the tension spring or the clip join, lever it out with a flat screwdriver, and free the outer lip of the seal from the front panel all the way around.
- Fold the boot inward through the door opening to reach the inner clamp that fixes the seal to the drum tub.
- Release the inner clamp and pull the old boot off the tub lip. Note the top locating mark or drain hole so the new one goes on the same way up.
- Clean the tub and panel lip so the new seal seats against clean, dry rubber-free surfaces.
- Fit the new seal onto the tub first, lining up the locating mark at the top, then refit the inner clamp.
- Seat the outer lip into the front-panel groove all the way around, then work the outer spring back into its groove evenly so the boot sits flat with no puckers or twists.
- Reconnect power and water, and run an empty rinse-and-spin. Watch for leaks before washing a real load.
The springs are the fiddly part. A boot fitted with a twist, or a lip not fully pushed home, is the usual reason a seal still leaks after fitting — so take your time.
Which seal fits my Haier model
The replacement seal (part reference H0020300937) fits:
- HWX8040DWI — the 8kg + 4kg TwinTasker (this seal is for the 8kg front-load drum)
Your model number is on the model sticker inside the door frame or on the rear panel. If your Haier isn’t the HWX8040DWI, use the part finder to match the correct seal — Haier used several boot designs across its front-loader range.
Door seal replacement cost in Australia
| Option | Estimated cost | Time |
|---|---|---|
| DIY seal replacement (part only) | $78.95 | 45–60 minutes |
| Tradie call-out + seal fitted | $220–$360 (labour + part) | 1–1.5 hours |
At $78.95 the part is the smaller share of a tradie’s bill — most of that quote is the call-out and labour. If you’re comfortable working the retaining springs, this is a very achievable DIY job.

Frequently asked questions
Is this a genuine Haier door seal?
This is a quality replacement seal made to fit the TwinTasker HWX8040DWI. It does the same sealing job as the original boot.
The TwinTasker has two drums — which one does this seal fit?
The main 8kg front-load drum, behind the round front door. The smaller 4kg top drum uses a different lid setup and isn’t sealed by this boot.
Can I fit the seal myself?
Yes. It’s a hand-tool job with no electrical work once the machine is unplugged. The retaining springs take patience, so allow an unhurried hour.
My TwinTasker keeps growing mould on the seal — why?
Front-load drums trap water in the seal fold. Leaving the door ajar between washes, wiping the fold dry and running a monthly hot cycle all help. Once mould has soaked deep into the rubber, replacement is the only lasting fix.
Will a new seal fix the leak for good?
If the leak was from a failed boot, yes — as long as the new seal is seated evenly with the springs fully home. Run an empty rinse-and-spin to confirm before a full load.
How long does a TwinTasker door seal last?
Typically five to eight years depending on wash temperatures, detergent use and how well the fold is kept dry between washes.
