Ask someone to picture an AIRBELT E3 Premium and they will describe a black one. 8224SWER is the panel over the filter bay in that finish, and SEBO prints it at item 24 on the drawing for the range, so shade and diagram number identify the same component from two directions.There are only three places these panels ever give way. The catch goes first; then the hinge tabs; then a corner, on machines whose covers get prised off with a thumbnail rather than released. Whichever fails, the outcome is identical: a filter with room to move. Air is lazy and will take a low-resistance gap at the rim over the higher-resistance route through the media every time, so the machine carries on sounding healthy while filtering less than it should. A new panel puts the media back square and shuts the compartment as designed. The job needs no tools beyond what a filter change already asks for, and the existing filter goes straight back in.The SW in the middle of the number is SEBO's code for black, and it recurs on the AIRBELT E sheet wherever a part shares the body colour: 8328SWER is printed as the black top casing at item 22, and 8249SWER as the black exhaust air filter cover at item 4. Those are diagram references rather than fitment claims, but they are handy when a repair needs more than one panel and the finishes have to agree.
