Question about De'Longhi La Specialista
My machine builds up overpressure all the way to the stop. Even if I test the portafilter without coffee and without a sieve inserted, the pressure gauge turns all the way to the stop and the portafilter sits properly under pressure. The central hole in the cup is clean and open. If I let the machine press with only the portafilter but no cup at all, the right amount of hot water comes out, so the water supply is probably OK. The machine is also freshly descaled.
Helpful answer
I cleaned everything again and cleared the small hole with a needle. Thank you, now it works again.
I have also had this problem a few times, but it was always due to a clogged sieve. Sometimes it can happen that a crumb of coffee powder gets lost there, at first it is not noticeable, but if the pressure does not release, it can almost only be due to this cause.
