Possible Causes
Worn drip-stop valve seal, coffee residue preventing valve closure, weak drip-stop spring.
How to Fix / Troubleshooting
Safety: Allow the machine to cool before working near the brew head.
- Clean drip-stop: Remove the filter basket and inspect the drip-stop mechanism. Clean all moving parts with warm water and a brush.
- Check spring action: Ensure the drip-stop moves freely and returns to the closed position when the carafe or cup is removed.
- Descale brew path: Run a descaling cycle to remove scale that may prevent proper sealing.
- Replace valve: If the drip-stop or internal brew valve seal is damaged or deformed, replace the valve assembly or seal kit.
