Yes, the connected waste must meet the appliance's installation requirements for water to leave properly. A grinding motor can operate while an unsuitable or restricted outlet arrangement prevents effective discharge.
What the observation tells you
An outlet that was rearranged during cabinet or sink work deserves attention when symptoms began at the same time. Do not lift the disposer, tilt it or force a pipe into a new position to imitate a diagram. The relevant dimensions must be assessed as an installation.
A useful next step
Provide photographs of the accessible route and the recent-work history. Ask the installer to check compliance with the exact model's drainage instructions before attributing poor clearing to motor power.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
