Quick answer: For anyone whose Bosch front loader is leaking at the door, stopped with a drum full of water and E18 showing, or will not lock and start. Across Serie 4, 6 and 8 the parts that fail most are the door seal, the drain pump, the Aquastop inlet hose and the door interlock. All stocked in Australia and dispatched from Sydney the day you order (12pm Sydney cut-off). What matters is matching the full E-Nr on the model sticker inside the door rim, index included.

The moment you’re in
The Serie 6 has finished its spin and a puddle is creeping out from under the door. Or it is 9pm, the WAW has stopped mid-cycle with a drum full of grey water and the display says E18. Or you pressed Start, heard the door go clunk, and nothing else happened. Three different evenings, one short list of parts.
Bosch sells a lot of front loaders in Australia through the big retailers, and the Bosch washer door seal is one of the seals Australians replace most often. The catch is that Bosch matches them by the full E-Nr, index included, and getting that right is the whole game.

The Bosch door seal is the grey rubber bellows between drum and door. It splits at the fold, grows black mould in the drain channel, and tears when a bra wire sits in the fold for a few spins. It is a $45–120 part, and on most Bosch models it comes off from the front without pulling the machine apart. The door seal replacement walkthrough covers the retaining wire and drain-hole orientation; leaking from the door seal shows how to tell seal from door glass.
The family is the first three letters of the E-Nr:
- Serie 4: WAN, WAK, WAT. Entry and mid-range; two table listings cover WAK and WAT.
- Serie 6: WAT, WAU, WGG. The WAU28490AU and the WGG24400 series are the big two, each with its own guide: the WAU28490A parts guide and the WGG24400 series parts guide. WAT appears here and in Serie 4, so the prefix alone will not settle it.
- Serie 8: WAW, WAP, WGA. Top of the range. The WGA and WAW seals are different listings; the Serie 8 WAW and WAP guide covers the rest.
- Older Avantixx and Logixx WAS machines. Still running in plenty of Australian laundries; seals are in the table.
The prefix gets you to the right shelf. The full E-Nr picks the part.
E18 and not draining: pump, filter, cap
E18 is the Bosch drain fault: the machine timed out trying to empty. Before you buy anything, open the bottom-front hatch, put a towel and a shallow tray down, and pull the filter. Coins, hair clips and the odd sock end up here, and a blocked filter throws E18 exactly like a dead pump. Filter clear, drum still full, pump humming or silent: it is the pump. The not draining guide walks the checks in order, and which Bosch drain pump fits your model sorts the WAW, WAP, WAS and WGA variants, with and without the filter insert. Budget $60–100.
The filter cap is a separate, cheap part; it cracks when wound in too hard, and a drip from the hatch on a machine that otherwise drains fine is usually just that. Other Bosch codes are decoded on the appliance error codes page.
Won’t fill, won’t lock, loud on spin
E17 with no water arriving means the tap is off, the mesh filter at the hose’s machine end is blocked, or the Aquastop hose has tripped. Its tap-end valve has a small window; red means it has done its job and gets replaced, not reset.
A door that goes clunk but will not start, or will not release at the end of the cycle, is the interlock or the latch. The door won’t lock or won’t start guide covers the WAS24460AU and WAS32742AU; the logic holds across the range. Fit an interlock after diagnosis, and never bypass one.
A roar on spin that gets worse week by week, with a drum you can rock by hand, is bearings. Loud noise: bearings or belt separates the two. On a Bosch it is a full strip-down, and on sealed-tub models the bearings come as a whole tub: the point to weigh a repairer’s quote against the machine’s age. For interlocks and bearing kits, send the E-Nr and we will say what we can match.
Where the model sticker is and how to match a Bosch
Open the door. The model sticker is on the rim of the opening, usually at the bottom or right. Find the line marked E-Nr. It reads like WAU28490AU/01: family and model, a slash, then a two-digit index. The FD number beside it is the production date; you do not need it.
The index is the bit everyone skips and the bit that matters. Bosch keeps a model on sale for years and changes parts mid-run; the index counts those revisions. Two machines with the same model on the sticker can carry different pumps or seals if the index differs, which is why the listings above spell out /01, /09, /17 and /21. Type the full E-Nr, slash included, into the site search, or start from the Bosch models hub. If a listing names your model but not your index, do not guess: send the whole string through the contact page and we check it before you order. The Bosch E-Nr guide has photos of the sticker; find your model covers the other brands.
Bosch dishwasher parts
Honest answer: we hold very little Bosch dishwasher stock today. Washing machine parts are the deep shelf; Bosch dishwasher pumps, spray arms and door seals are thin. Send the dishwasher E-Nr (sticker on the door edge) through the contact page and you will get a plain yes or no, not a back-order.
DIY or repairer?
A door seal or drain pump on a Bosch is a Saturday-morning job with a screwdriver, pliers and a towel. Unplug at the wall and turn off the tap before you touch anything. Parts run $45–120 for a seal and $60–100 for a pump, against a repairer call-out and diagnosis of typically $100–165 before anything is fitted. If you can pull the filter, you can do the pump in an hour. The seal is a two-hour job with a hose clamp.
Stop and call a repairer for bearings, a control module, or anything electrical you cannot identify with confidence. Control modules are fit-after-diagnosis, never a guess. If the machine is past ten years and the quote is nearing half the price of a new one, weigh it honestly. Know the right part, then decide who fits it. Repairers can open a trade account.
Frequently asked questions
Q: Where is the model number on a Bosch washing machine?
A: On the model sticker inside the door rim, on the line marked E-Nr. Copy all of it, slash and two digits included, for example WGA254U0AU/01; that index separates two parts that look identical.
Q: What does E18 mean on a Bosch washing machine?
A: Drain fault: the machine timed out pumping out. Clear the filter behind the bottom-front hatch first; if it was clean and the drum is still full, the drain pump is the usual replacement.
Q: Can I replace a Bosch washing machine door seal myself?
A: Yes, on most models. The seal is held by a wire ring on the door side and a spring clamp on the drum side, and comes out through the front. Unplug first, note the drain-hole position before you pull the old one, and allow a couple of hours.
Q: Do you stock Bosch dishwasher parts?
A: Very little today; our Bosch range is built around washing machines. Send the dishwasher E-Nr via the contact page for a straight answer.
Q: How quickly do Bosch parts ship in Australia?
A: Get it to us by 12pm Sydney time and it leaves our Northern Beaches warehouse the day you order, Australia-wide. Stock shown on the product page is held here in Sydney, not on a boat.
All our Bosch parts sit under Bosch parts; the washing machine parts store covers the rest of the laundry. Find the E-Nr on the sticker inside the door rim and search it on the site, or send the full model number via the contact page and we will match it before you order. Dispatched from Sydney’s Northern Beaches the day you order when it is in by 12pm Sydney time.
