Possible Causes
Worn brew head gasket, Debris on sealing surface, Deformed capsule holder, Excessive pressure due to blockage
How to Fix / Troubleshooting
Safety: Allow the machine to cool before touching the head area.
- Clean sealing surfaces: Open the handle, remove the capsule holder, and wipe the rubber gasket and surrounding plastic with a damp cloth to remove coffee oils and grounds.
- Inspect gasket: Check the brew head gasket for cracks, flattening, or missing sections. If damaged, it should be replaced.
- Check capsule holder: Ensure the holder is not warped or cracked and that capsules sit flat.
- Descale and clean injector: A blocked injector can raise pressure and cause leaks. Clean the needle and descale the machine.
If leaks persist after cleaning and descaling, the brew head gasket or entire head assembly may need replacement.
