E06

The garbage disposal runs, but water backs up into the sink; E06 or a drain icon is shown on some Tweeny models.

Drainage Restriction / Outlet Blockage

E07

The garbage disposal runs but leaks from the bottom housing; E07 or a leak warning is displayed on some sensor-equipped Tweeny models.

Internal Seal / Housing Leak

E08

The garbage disposal will not run, E08 is displayed, and the reset button immediately trips again.

Ground Fault / Short Circuit Protection

E09

The garbage disposal runs but is extremely noisy; E09 (vibration/noise warning) is displayed on some smart Tweeny models.
