Code E24
high severity
GE models: GE introduced a manual filter assembly around 2010; earlier models had a self-cleaning grinder. On manual-filter models, lift off the lower spray arm, then twist out the cylindrical filter and remove the flat mesh screen beneath it — clean both. Check the model year before disassembling.
Common causes
- Filter clogged (check first)
- Drain hose kinked or pressed against the cabinet wall
- Household drain or garbage disposal inlet blocked
- Drain pump impeller jammed
Step-by-step fix
- Clean the filter (see E22 steps).
- Pull the machine out slightly and straighten the drain hose.
- Check the high-loop or air gap if fitted.
- If connected to a garbage disposal, confirm the knockout plug was removed at installation.
- Run a drain cycle to test.
