Learn how to replace the group gasket on your Profitec Go espresso machine. Step-by-step instructions for removing the old seal and installing a new silicone O ring gasket 03181.

Quick Answer

To replace a Profitec Go group gasket, remove the old gasket, clean the groove, then press the new silicone O ring gasket 03181 into place. Reattach the shower screen and test for leaks.

When to Replace the Group Gasket

A worn group gasket causes leaks around the portafilter or a loose fit when locking in. Replacing it restores proper seal pressure and prevents water from dripping onto the drip tray. The silicone O ring gasket 03181 is a direct replacement for the Profitec Go, offering heat resistance and durability compared to standard rubber gaskets.

What You'll Need

The replacement gasket is the only required part. A flathead screwdriver or gasket removal tool helps pry out the old gasket. A clean, lint-free cloth is useful for wiping the groove. No special tools are needed for installation.

Step-by-Step Replacement Guide

1. Remove the Shower Screen: Unscrew the shower screen retaining screw (usually a Phillips head) located in the center of the group head. Lift off the shower screen and set it aside. Keep the screw and screen together to avoid losing them.
2. Remove the Old Gasket: Use a flathead screwdriver or gasket removal tool to gently pry the old gasket out of the groove. Work around the circumference to loosen it evenly. Be careful not to scratch the group head surface. If the gasket is stuck, apply gentle heat from a hair dryer to soften it before prying.
3. Clean the Gasket Groove: Wipe the groove clean with a damp, lint-free cloth to remove coffee oils and debris. Ensure the surface is dry before installing the new gasket. Residual oils can prevent the new gasket from seating properly.
4. Install the New Silicone Gasket: Press the new O ring gasket 03181 into the groove with your fingers, starting at one point and working around. Ensure it sits flush and evenly around the entire circumference. Do not twist the gasket; it should lay flat without bunching.
5. Reattach the Shower Screen: Place the shower screen back over the gasket, aligning the screw hole. Tighten the retaining screw firmly but do not overtighten—just snug. Overtightening can strip the screw or warp the shower screen.
6. Test the Seal: Lock in an empty portafilter and run a short brew cycle. Check for leaks around the portafilter edge. If water escapes, the gasket may not be seated correctly or you may need a thicker gasket. A few drops are normal; a steady stream indicates a poor seal.
7. Enjoy Your Espresso: Once the seal is verified, your Profitec Go is ready for use. The new silicone gasket should provide a reliable seal for many months of daily brewing.
