Troubleshooting My Philips/Saeco espresso machine asks me to "empty coffee grounds container" even though it's not full Sometimes, your Philips/Saeco Espresso machine might display 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 you to empty the coffee ground container. If you empty the coffee ground container before the machine requires you to, the system will not reset and it will ask you to empty the container before it is completely full. Try to empty the coffee ground container only when prompted to prevent these mix-ups from happening.
