Sink Flange Seal Failure

E08

Garbage disposal leaks from the side where the dishwasher drain hose connects, internal LED flashes eight times when moisture is detected near the dishwasher inlet.

Control Switch or Air Switch Input Failure

E11

Garbage disposal starts but immediately shuts off within 1–2 seconds, internal LED shows a single long flash followed by one short flash (11).

Rotor Position or Start Circuit Fault (Electronic Start Models)

E12

Garbage disposal runs but emits a strong burning smell and may produce light smoke from the bottom vents, internal LED flashes twelve times and then locks out.

Motor Overheating / Insulation Breakdown

E13

Garbage disposal runs intermittently; sometimes it starts, other times nothing happens when the switch is flipped, internal LED flashes thirteen times when a start attempt fails.

Intermittent Power or Internal Relay Fault

E14

Garbage disposal runs but is unusually loud and vibrates excessively, internal LED flashes fourteen times indicating imbalance.

Cross-Drain Blockage / Incorrect Trap Configuration

E16

Garbage disposal does not respond, but internal LED is solid red (no flashing pattern).

Lockout Condition / Safety Interlock Engaged

E17

Garbage disposal runs but water leaks from the side discharge connection where the drain pipe attaches, internal LED flashes seventeen times when moisture is detected at discharge.

Discharge Gasket or Coupling Leak

E18

Garbage disposal emits a high-pitched whine but does not grind effectively; food remains largely intact, internal LED flashes eighteen times.

Worn Grinding Components / Reduced Torque

E19

Garbage disposal runs but causes lights to flicker or dim significantly when starting, internal LED flashes nineteen times indicating high inrush current.

Excessive Start Current / Electrical Supply Issue

Symptom

Garbage disposal causes the sink to shake or vibrate heavily when running.

Excessive Vibration / Imbalance

Symptom

Garbage disposal emits a foul odor even after running with water.

Organic Buildup / Biofilm in Grinding Chamber and Drain

Symptom

Garbage disposal hums loudly but does not spin; after a few seconds it may shut off.

Impeller Jam / Locked Rotor (No Code Display)

Symptom

Garbage disposal is extremely noisy, with rattling or clanking sounds during operation.

Foreign Object or Loose Component Noise

Symptom

Garbage disposal is unusually hot to the touch after short periods of use.

Overheating Motor

Symptom

Garbage disposal leaks only when the dishwasher is draining.

Dishwasher Drain Backflow or Inlet Leak

Symptom

Garbage disposal makes a grinding noise even when empty and with no food present.

Internal Component Contact / Misalignment

Symptom

Garbage disposal motor runs, but the grinding plate does not move; no grinding occurs.

Sheared Coupling / Disconnected Rotor

Symptom

Garbage disposal runs but does not grind food effectively; food particles remain large and are not flushed away.

Reduced Grinding Performance

Symptom

Garbage disposal runs but water leaks from where the power cord enters the bottom of the unit.

Cord Entry Grommet Leak / Internal Water Intrusion

Symptom

Garbage disposal runs but water slowly seeps from the seam between the upper and lower housing sections.

Housing Gasket Failure

Symptom

Garbage disposal splashes water and food particles back out of the sink opening during use.

Ineffective Splash Guard / High Back-Splash

Symptom

Weak Start Circuit / Failing Capacitor

Symptom

Garbage disposal switch produces a loud pop or spark when turned on or off.

Arcing Wall Switch Contacts
