A short recording should show the control used, the sound and the visible sink behaviour from a safe distance. State whether water was running and whether food had just been added.
What the observation tells you
Do not repeat an unsafe event to make a recording. Leaks near electrics, smoke, a stalled hum, severe movement or a protection trip require stopping, not a longer demonstration. Keep hands, camera and loose straps away from the opening.
A useful next step
Send an existing recording with the model reference and a brief written description. If no safe recording is possible, explain the event in words; an engineer can assess the appliance without a video.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
