Bezzera parts and where to buy

Numbers are Bezzera's own, from its BZ10 spare-parts catalogue (9942047.05, 09/2026), tables "from 01/01/2020". Pick your region for a seller that lists the part. A ≈ means the listing matches by name or size, or does not state the 2020 number, so check the fit before you order.

Bezzera prints no quantities. The pump, fill valve and element differ by voltage.
