The O-ring 10210M is a brew group piston seal for Philips EP and HD series fully automatic coffee machines. If your machine has started leaking water underneath, coffee is flowing very slowly or only dripping, and the pump has become noisier, the cause is typically a worn piston seal. This food-safe red silicone part restores the seal, pressure in the brew unit, and consistent espresso flow.
Important — verify your model: before ordering, check the exact model and version of your machine on the type plate (usually on the underside of the appliance or behind the water tank) to ensure this part is guaranteed to fit your machine.

- Coffee flows very slowly, drips, or does not come out at all
