Possible Cause
The cutter or impeller are jammed
preventing the motor from turning.

Check valve stuck closed.

If the macerator was installed with a ball
valve in the discharge line, valve may be
closed.
Air lock.
Volute inlet plugged.

Strainer basket requires cleaning.
Unit not vented correctly.
The macerator is either not plugged in,
