I’ve not done that particular model but the normal prodedure for models after the Softwave / New Wave series is roughly:
Detach door seal from cabinet, remove motor and disconnect hoses & wiring from tub, move soap drawer housing, timer etc out of the way, lift tub out of the top, remove tub front section, remove inner drum, change bearings.
On Connections 5031689262194 is listed as fitting SE220.
Thats a 30x52x11/12.5 seal.
So the front bearing for that model would be 6205 and it’s very likely that 6204 would sit behind that. Since these fit lots of other Hoover models too it would be likely that you could do this job just using what’s in your van already. (Small Zanussi seal is 30x52x10/12 IIRC).
Course there’s no guarantee. If you want to be sure try Drulight (01443)
812372. They’re brilliant for Hoover/Candy spares by post.
