The spring and metal ball (part no. 33322D) are small but critical components of the grind-adjustment mechanism in DeLonghi coffee machines. If your grind-coarseness setting will not hold, the grinder dial "skips" or turns too freely, or the burr unit moves on its own, the most common cause is a fatigued spring or a missing ball. This part is the correct replacement for restoring firm detent retention of the grind setting.
Important — verify your model: before ordering, confirm the exact model and version of your machine from the rating plate (type label), which is normally located on the underside of the appliance or behind the water tank. Check the full type designation (including the series and version code) to ensure this part fits your specific grinder.
When does this part need to be replaced? (Fault symptoms)
This part typically fails when you notice one or more of the following symptoms:
- The grind-coarseness setting will not hold — the dial returns to a previous position or the grind level changes on its own during brewing
- The grinder adjustment dial "skips", clicks loosely, or rotates too freely with no discernible detent positions
- The burr unit moves on its own, resulting in coffee that is alternately finer or coarser without any input from you
- On disassembly of the grinder, the metal ball is missing or the spring is cracked, deformed, or displaced
