1/2 a litre of very hot water inside a heat-
resistant container.
- Place the diffuser screen(s) and diffuser
screw(s) in the solution and leave them
fully submerged for about 30 minutes.
7) Cleaning the gigler
The gigler (or restrictor) on a GB5 group
cap can be located under the solenoid
valve. In order to access the gigler you
must irst turn off the water to the machine
and de-pressurise the coffee boiler.
To remove the solenoid valve you will need
a 4mm allen key. Loosen the two allen
screws and lift off the solenoid body from
the group cap. Be careful not to lose the
two ‘o’ rings. The gigler can be removed
from the hole in the group cap with a 2mm
allen key.
Clean the gigler with a mild de-scaling
solution and/or a ine wire (such as a guitar
string)
Re-assembly is the reverse of dis-assembly.
