Stop using the affected discharge route and explain the timing when requesting help. The dishwasher connection, adjacent plumbing and disposer need to be considered together; the source is not established by which appliance was last repaired.
What the observation tells you
Water may travel along a hose or housing before dropping into the cabinet. Do not pull the hose, loosen a clamp or run repeated empty cycles to watch it. Avoid electrical connections in a wet cabinet.
A useful next step
Provide the dishwasher and disposer details, plus any recent connection work. Ask whether the dishwasher must remain unused until the leak is assessed rather than assuming its separate power switch makes the water path safe.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
