Before buying wdt tools
Does any 51mm WDT tool fit the De'Longhi La Specialista Arte Evo?
No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. A De'Longhi replacement filter assembly for EC9255M shows a 51mm La Specialista-style three-lug portafilter. Treat whole portafilter swaps as La Specialista-family fitment, not generic Dedica/Stilosa/ECP 51mm fitment.
Is a WDT tool the first upgrade to buy?
It is first in this machine's stored upgrade order, but confirm the problem it solves and the prerequisites before buying.
