The view from the sink opening is not enough to establish a blockage or a leak. The chamber and connected trap arrangement differ between installations, and lighting can make a damp surface look like standing water.
What the observation tells you
Keep the appliance off and do not reach in, probe the depth or run the motor merely to change the view. The more useful observation is whether normal sink water has recently drained freely, accumulated or returned from elsewhere.
A useful next step
If drainage behaviour has changed, describe that change and any smell or backup. Let an engineer assess the actual water path instead of deciding from a photograph of the opening alone.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
