Hi John,
I just replaced the door seal on a Bosch WFL246KGB/04. It took 40mins flat, including time for two Buds and a sneaky fag! Assuming yours is the same build style as above, here goes......
Guess you have already removed the door and the front panel (after removing the outer gasket spring clip)? The inner spring goes on, after you fit the gasket. Ease on the gasket, around the plastic outer drum, ensuring that the lip of the gasket locates fully with the drum recess. Before fitting, take a damp cloth to the outer drum lip and wipe all the gunk off. Get right inside the gap between the plastic outer and stainless steel inner, 'cos any residue on the sealing edge is going to make the seal leak. Some recommend using some soft soap or other lubricant before fitting the gasket, but it's really not necessary. Make sure the gasket goes on as it should. The moulded 'dent' in the inner gasket face should be at 6 o'clock. Once you're happy that the gasket is fully engaged on the plastic outer drum, you replace the spring in the gasket recess. It's best to keep the ends of the spring at 12 o'clock and then stretch the spring out, working around the circumference of the gasket. Three hands would be good here, but if you are on your 'Jacks', a bit of perseverance pays off (here's where the Buds come in!). Once you have that on, re-fit the front panel (At this stage, remember to re-connect the door catch sensor plug, on to the door catch). Then, after wiping around the recess in the front panel, ease on the outer gasket, into the pressed steel profile in the front panel. As with the inner gasket lip, it's obvious when it goes on right, as you can see it 'seats' properly. Then re-fit the outer spring retaining ring, which you may need a small, blunt, flat bladed screwdriver to lever the solid wire ring into the recess. Then, replace the door, replace the bottom panel and BINGO, seventy quid saved and time for a self-congratulatory Bud and a fag (optional!). Hope this helps. TTFN :-)
