No part — clean filter, pump & hose
Remove and rinse the filter, clear the pump impeller of debris/glass, and check the drain hose for kinks and the disposal knockout plug. Clears many E24 codes.

Safe to Try · Know the Risk · Call a Pro
General guidance, not professional advice. Always unplug the appliance (or shut off the gas/water) before you check anything. If it feels beyond you, that's exactly when to get a pro.
✅ Safe to try yourself
- Remove and rinse the filter; check the pump impeller for lodged debris/glass.
- Check the drain hose for kinks and clogs at the high loop and disposal.
- Confirm a newly-installed disposal's knockout plug was removed.
⚠️ Doable — know the risk
- Drain pump replacement — moderate; power and water off.
🛑 Call a pro — don't touch this
- A leak reaching the wiring, or a control fault.
