If you have purchased this seal and decide to go ahead with the repair yourself, please TAKE CARE.

Do not go ahead if your Coffee Machine is NOT in good condition. We’re trained to do this sort of stuff. If you decide to do this repair and you have a problem, give us a call. Parts are sold with the understanding that we can’t be liable if the repair fails.

Firstly, turn the machine off, unplug from the wall, and let it cool down.

Get a 5/32" Allen Key and unscrew clockwise the small screw which is holding the metal filter grid on in the brew head assembly. Don't force it as you may shear the screw off. Use a thin screwdriver to gently ease off the grid.


Ease the Group Head Seal out of the machine with the screwdriver and dispose. Clean the grid of coffee residue, and also clean out the cavity of the coffee machine.


Fit the seal back into the machine ridge side down, then refit the grid onto the seal. Re-secure with the screw anti-clockwise, being careful not to overtighten.
