A damaged housing or latch needs assessment before normal use. The filter's position may affect the intended airflow and containment of fibres.
Understanding this situation
Do not tape, wedge or weight the assembly into an approximate position. Even if the machine starts, that does not confirm correct fitting or safe operation. A broken clip can also damage another part when forced.
A useful next step
Provide the complete model and describe which component no longer seats normally. Use the correct compatible repair route. Do not run without the filter or cover while waiting for a replacement to arrive.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
