How to get that coffee free-flowing once again.
But now it's doing it again. The coffee comes through very slowly and nothing seems to help. I don't have a warranty but I believe it's about three to four years old.
Gaggia recommend the following steps: 1. Take off the coffee handle, look into the unit and you will see a screw. Undo it with a flathead screwdriver and the shower disc will drop out.
2. Undo the two allen-key screws inside the unit to let the shower head come out (you need to play with it a little to loosen it).
3. Clean the head and disc in soapy water, put them back and descale. Gaggia do have an out-of-warranty pick-up service, but it costs pounds 102.
