Troubleshooting My Philips/Saeco espresso machine prompts "empty coffee grounds container" even though it's not full Sometimes, your Philips/Saeco Espresso machine might show a message requesting to empty the dump box without it being completely full. Find out what to do. Empty when prompted After a certain amount of brewed coffees, your espresso machine will prompt to empty the coffee ground container. If you empty the dump box before the machine requires you to, the system will not reset and therefore ask you to empty the coffee ground container without it being completely filled. Try to empty the dump box only when prompted to prevent these mix-ups from happening.
