DF64 Gen 2 Anti-Static System
Updated September 9, 2026.
The DF64 Gen 2 uses a plasma ion generator near the grounds outlet to reduce static. It can make dosing cleaner, but it does not eliminate every stray particle or replace chute maintenance. Coffee residue on the probes and changes in humidity can affect the result.
Static, retention and clumping are different
Static makes grounds cling to surfaces or scatter. Retention is coffee remaining inside the grinder. Clumping is grounds gathering together. These problems can overlap, but a plasma system primarily addresses electrical charge. It cannot push a compacted blockage out of the chute or guarantee that every dose weighs exactly the same as the beans you loaded.
Start with the coffee path
If mess increases, check that the cup is centered and that beans have finished feeding. Switch off and unplug the grinder before inspecting accessible chute parts. Brush away dry residue following your model’s cleaning instructions. Treat the ionizer probes gently: do not bend them, scrape them with sharp tools or introduce water into the outlet. See DF64 Gen 2 cleaning and care for the broader maintenance routine.
A practical troubleshooting sequence
First clean and reassemble the accessible outlet components. Then grind a measured dose of the same coffee and compare the output and mess with your previous result. If static improves, resume normal use and inspect the area as needed. If output remains restricted or the motor struggles, stop and contact support rather than repeatedly grinding into a blocked path.
| Symptom | Possible explanation | Useful next step |
|---|---|---|
| Fine grounds cling to cup | Dry conditions or dirty probes | Clean dry, center cup and compare another dose |
| Very little coffee exits | Restricted chute or feeding problem | Stop and inspect according to the manual |
| Output varies after a big setting change | Coffee left from the prior setting | Use a consistent clearing routine and verify dose |
| New static after cleaning | Incorrect reassembly or damaged probe | Check the assembly and ask support |
Do you need to spray the beans?
RDT means lightly adding moisture to beans before grinding. The plasma system means this is often unnecessary. Start without it; do not use water to compensate for a dirty chute. If the instructions for your unit allow a light mist, use it sparingly and keep water away from electrical and internal components. Excess moisture can make residue harder to clear.
