Elektra Grouphead Maintenance Kit for Commercial Machines Only

This part is placed in through the top of the top mushroom nut of the grouphead. Should be replaced every 6 to 12 months.

This part can be replaced once the above stainless steel filter is removed. Typically, an 8mm socket wrench is needed to remove. It is difficult to place the new one in. Sometimes, pliers need to hold the new one just to start the threading process. Should be replaced every 6 to 12 months.

This part should be replaced at the same time as the injector. Screw in the injector into the support so you can install both parts in through the top of the grouphead at the same time.

This part usually prevents leaking at the junction between the portafilter and grouphead. If hardened, it will need to be scraped and chiseled out. If replaced every 3-6 months, it is easier to remove.

Should be replaced every 3 to 12 months.
