If you’re having trouble getting a good seal at your group head, or water is leaking when you brew espresso on your Quick Mill Arnos, you may need to replace your group gasket. This article, as well as the attachment at the end of this article, offers a guide on replacing the group gasket on your espresso machine.
Your group gasket is what creates the seal between your portafilter and your group head. On average, group gaskets should be replaced once a year. Common signs of failure are water leaking around the portafilter while brewing, and being able to easily lock the portafilter way past the middle position while brewing. It is a good idea to replace the group gasket once a year, as the older a gasket gets, the harder it is to remove. The instructions in the attachment at the end of this article will make replacing your group gasket a breeze. If you are unsure which replacement gasket to buy, please consult a member of our technical support team.
