Use an accessory compatible with the sink opening and the manufacturer's resting arrangement. A strainer can help collect unwanted scraps while the appliance is idle, but it must not become a loose object that could enter the chamber.
What the observation tells you
Empty collected material into the appropriate waste route instead of forcing it through the strainer. Before grinding, set the accessories exactly as the model's instructions require; a water-holding position may be unsuitable for operation. Batch-feed controls need particular attention.
A useful next step
Keep a damaged or poorly fitting strainer out of use. Choose the approved accessory from the full appliance details rather than relying on its diameter alone.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
