Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker and allow any hot water to cool before opening the basket.
Clear basket and drip stop:
- Open the brew basket carefully; remove filter and coffee grounds.
- Rinse the basket thoroughly, paying special attention to the drain hole at the bottom.
- Operate the drip stop lever several times under running water to ensure it opens and closes freely.
Adjust coffee grind and load:
- Use a medium grind suitable for drip coffee, not espresso-fine.
- Do not overfill the filter; follow Ninja's recommended scoop counts.
Test:
- Reassemble and run a water-only brew to confirm proper drainage.
If E09 continues, the drip stop assembly or basket sensor may be damaged and require replacement.
