Cleaning the gasket and shower plate
WARNING!
Take special care to avoid scalding when
performing this cleaning operation, as the
hot water used to clean the gasket will
spill over the sides of the porta-lter.
WARNING!
Do not fully tighten the porta-lter. If fully
tightened, high-pressure water may spray
out and cause scalding or serious injury.
When placing the porta-lter lled with grinded coffee into the brewing group, left overs will accumulate in the
closing surface. If these remains are excessive it can prevent a good closing between the porta-lter and the
group head.Moreover, these remains can even block the dispensing of water through the group head.
To prevent this perform the following cleaning:
Place the cleaning membrane in the lter basket (without detergent).
Insert the porta-lter in the group head, but do not tighten fully (the porta-lter should be loose).
Press the Continuous Dispensing button on the button panel.
Make an opening-closing movement of the porta-lter in place without closing it. Water will now ow
around the porta-lter, owing through the closing surface and cleaning it.
