Common faults on the Bosch WGG24400 series
The Bosch WGG24400 series — WGG24401AU, WGG24402AU, WGG244A0AU, WGG24409AU, WGG2449RAU and WGG244ARAU — is one of Bosch’s current-generation front-loader families in Australia. These machines are still young by washing machine standards, so the faults that show up are the early wear points: the door seal (mould and small tears from trapped moisture) and the door interlock switch. The drive belt is the third item worth knowing about, as it is shared with a long list of other Bosch front loaders and is an inexpensive fix if the drum stops turning.
Before ordering parts, locate the model sticker on the door jamb (the frame exposed when you open the door). The WGG family variants look nearly identical from the front, and the interlock switches differ between variants — WGG24409AU/01 and WGG2449RAU/01 take one switch, WGG244ARAU/01 takes another — so confirm the full model number including the suffix after the slash before ordering.
| Part | Symptom | Price | Link |
|---|---|---|---|
 Door seal (WGG24401AU/01, WGG24402AU/01, WGG244A0AU/09) | Black mould growth in the folds of the rubber that no amount of scrubbing removes; water leaking from the front during the wash; visible tears or perishing | $109.95 | Buy door seal |
 Door interlock switch (WGG24409AU/01, WGG2449RAU/01) | Door won’t lock at the start of a cycle; machine refuses to start; door stays locked long after the cycle finishes | $43.95 | Buy interlock switch |
 Door interlock switch (WGG244ARAU/01, WAN24126AU/10) | Same lock symptoms on the WGG244ARAU variant and the related WAN24126AU — match the fitment list to your model sticker | $43.95 | Buy interlock switch |
 Drive belt (fitment includes WGG24401AU) | Drum not turning while the motor runs; squealing on start-up or during spin; washing still soaked because the drum never reached spin speed | $23.95 | Buy drive belt 1255J5 |
Diagnosis guide – Bosch WGG24400 series
- Note any error code first. If the display shows a code, write it down before touching anything. A door code points straight at the interlock switch; a drain code points at the pump filter behind the lower front flap, which you can clean yourself for free.
- Inspect the door seal in daylight. Pull back each fold of the rubber boot and look at the lower section where water pools after a wash. Surface mould can be cleaned; mould that has penetrated the rubber, or any split or tear, means the seal should be replaced. Our WGG24402AU door seal mould guide covers the judgement call and the replacement steps in detail.
- Check for leaks at the six o’clock position. A small puddle appearing at the front left or centre during the wash phase almost always traces back to the lower folds of the door seal rather than a hose. Run a short cycle and watch where the first drips appear.
- Test the door lock. Close the door firmly and press Start. If the machine never clicks the lock in and refuses to begin filling, the interlock switch has failed. If the door stays locked several minutes after the cycle ends, the switch is also the usual cause.
- Check the drum turns with the motor. If the motor runs but the drum stays still, or you hear squealing under load, the drive belt has stretched or come off. Spin the drum by hand — if it spins with no resistance, the belt is off or broken.
- Rule out the free fixes. Before ordering anything, clean the drain pump filter, check the door hinge closes the door square against the seal, and run a hot maintenance wash. On a machine this new, a surprising share of symptoms clear up with maintenance alone.
Fitting the parts yourself
The door seal is the main event on this family. Replacing it does not require moving the machine or opening the cabinet sides: the outer retaining ring comes off from the front, the old seal peels out, and the new one seats into the same channel. The job rewards patience — getting the drain holes at the bottom and the retaining ring tension right is what separates a dry laundry from a repeat leak. Allow about an hour the first time.
The interlock switch is a simpler repair: peel back the seal lip at the latch side, remove the two screws through the door jamb, and swap the switch through the gap. The drive belt requires removing the rear panel and walking the new belt onto the pulley. All three jobs need only basic hand tools. Unplug the machine before starting, and if you would rather not do it yourself, any appliance technician can fit these parts in a single short visit.
Frequently asked questions
Do WGG24401AU and WGG24402AU use the same door seal?
Yes — the door seal listed above is confirmed for WGG24401AU/01, WGG24402AU/01 and WGG244A0AU/09. As always, check the full model number on your model sticker, including the suffix after the slash, against the listing before ordering.
Why does the door seal on my WGG grow mould so quickly?
Front-loader seals trap a ring of water in their lower folds after every wash. If the door is closed between washes, that moisture never dries and mould establishes in the folds. Wiping the seal dry and leaving the door ajar between washes largely prevents it. Once mould has penetrated the rubber, replacement is the only real fix — the WGG24402AU mould guide explains how to tell the difference.
My machine won’t start and the door won’t lock — which switch do I need?
It depends on your exact variant. WGG24409AU/01 and WGG2449RAU/01 take one interlock switch; WGG244ARAU/01 (and the related WAN24126AU/10) take another. Both are $43.95 — read the model sticker on the door jamb and match it to the fitment list on the product page.
Where is the model sticker on a Bosch WGG?
On the door jamb — the frame exposed when you open the washing machine door. It shows the full model number and the variant suffix after the slash, both of which matter for seal and switch fitment on this family.
Is it worth repairing a WGG24400-series machine?
Yes — these are current-generation machines, and every part on this page costs a small fraction of replacement. A door seal at $109.95 or an interlock switch at $43.95 fitted at home keeps a near-new machine running for years; there is rarely a case for replacing the machine over any of these faults.
