Portafilter Overfilling - Espresso Maker

Were too many grounds added?

If the portafilter was overpacked with too many grounds, it could cause it to overflow. Tap the Portafilter to level the ground coffee bed and rest on a flat surface. Use the Tamper to tamp down the ground coffee. Sweep excess coffee grinds from the rim.

Are the grounds too dense? 

If the grounds were over-tamped it could cause the grounds to be too dense and won't allow water to pass through.  

TIP: Shot duration should be between 20-30 seconds for 1 and 2 shot selections. - If less than 20 seconds: decrease grind size and/or increase tamp pressure. - If more than 30 seconds: increase grind size and/or reduce tamp pressure.

Is the portafilter locked into place? 

Position the Portafilter under the Group Head with the handle aligned to unlock. Raise the Portafilter into the Group Head and twist to the right side to lock. If the portafilter is not aligned correctly, it could cause it to overflow.
