16. Cleaning the Shower Screen and Head Seal
After a period (say 6 months in domestic use and weekly cleaning) the shower screen will
become clogged with coffee oils that need to be removed. Proceed as follows:
• Dislodge the shower screen with its neoprene seal from the group head. This may be
accomplished by levering the screen downwards using the handle of a teaspoon. Lever
your way around until the unit drops out.
• Separate the seal from the screen and soak the screen in head cleaning compound until
clean. If this fails to adequately clean the item it will need to be replaced. Replace it
with any brand item designed for an E-61 group head.
• If the neoprene ‘O’ ring (head seal) is hard it too needs replacing. Any 6mm thick
(standard size) head seal for an E-61 group head will be satisfactory.
• Reassemble the seal to the shower screen ensuring the chamfered edge of the seal is
next to the open end of the shower screen. Failure to do this will make it difficult to
insert the unit in the group head.
• Insert the combined unit (open side uppermost) into the group head. Force the
neoprene seal up into the group head until it can go no further and seats evenly all the
way around. Use the handle of the teaspoon. Now insert the filter holder and pull to
the right until it is correctly located.
