Possible Causes
Carafe not fully seated on warming plate, Drip stop lever stuck in closed position, Carafe detection switch misaligned or failed, Debris under carafe platform
How to Fix / Troubleshooting
Safety first: Turn the unit off and unplug before adjusting mechanical parts.
Check carafe placement:
- Remove the carafe and inspect the warming plate for debris or coffee grounds.
- Clean the plate and the bottom of the carafe with a damp cloth and dry thoroughly.
- Re-seat the carafe firmly so it is centered and fully contacting the plate.
Inspect drip stop:
- Open the brew basket and locate the drip stop lever or valve.
- Ensure it moves freely; clean any dried coffee residue that may be preventing it from opening.
- Operate the lever several times to confirm smooth movement.
Test:
- Plug the unit back in and attempt a small brew.
If E04 continues, the carafe detection switch or internal microswitch may be faulty and require replacement.
