I took it apart. You know where this is going.

[SixString74]

Machine / revision: Rancilio Silvia V6 with PID
Country / voltage: Germany / 230V
Grinder / burrs / setting / calibration: Eureka Mignon Specialita; stock 55 mm flat burrs; about 1.4 turns from burr touch; dial position photographed.
Basket / portafilter: stock double basket; bottomless portafilter (58 mm system where applicable).
Bean / roast date: Honduras Marcala medium roast; roast date 2026-08-05.
Dose / yield / extraction time: 18.0 g in, 36 g out, 28 s target/current reference.
Water / temperature: filtered tap, about 80 ppm hardness; 92°C.
Exact symptom: Burr touch arrives before the useful espresso range on the dial.
Tests already performed: Establish true touch point with an empty grinder, then reset the dial reference Already cleaned the obvious removable parts and repeated the test once.
Diagnostic photograph or video: counter-space photo plus a 20-second workflow clip.

I cleaned the Eureka Mignon Specialita, which was apparently an act of aggression. The symptom is repeatable and I have stopped adjusting random things.

[SixString74]

Confirmed solution: I reseated the burr carrier, cleaned the mating surfaces, found true burr touch again and recalibrated from there. The old number was simply no longer the same reference. I am leaving the original numbers above intact so the next person can see what changed.

Short answer: Start with the simple reproducible test before buying parts.
Applies to which model/revision: Rancilio Silvia V6 with PID.
Likely cause: The symptom points first to a setup, wear-part or calibration issue that can be separated from a major failure.
Test to perform next: Return one variable to a known reference, repeat twice, and record whether the symptom changes in the same direction.
Expected result: If that subsystem is the cause, the symptom should change predictably rather than randomly.
Safety limit: Unplug before opening the burr chamber. Do not defeat interlocks or force a stalled motor.
Evidence: First-hand owner experience with the same model/configuration; not a manufacturer diagnosis.

Inference only: because the symptom is repeatable and your listed tests already rule out some obvious causes, I would suspect the narrowest remaining mechanical/setup path before a board-level failure. I would not buy a part from that inference alone.

The useful documented check is the revision-specific maintenance/service sequence, not a generic espresso-machine video. For Rancilio Silvia V6 with PID, verify the manual procedure and part number before opening or ordering anything. If the documented test does not reproduce the fault, stop treating that subsystem as proven.

Not the exact revision, but I had a closely related setup with the same general failure mode. The thing that saved time was separating the Eureka Mignon Specialita / puck-prep side from the machine side instead of adjusting both together. Similar experience, not proof for your unit.

This is a good example of why the exact revision and test history matter. “My Rancilio Silvia V6 with PID is bad” produces twenty theories; the measurements above at least give the theories somewhere to die.

[Mending Dumpling]

I would mark the part you changed and photograph the original position before going farther. Future you is an unreliable witness.

[Briefs And Books]

If you can post the short video mentioned in the opening block, the sound/flow pattern may separate a normal Rancilio Silvia V6 with PID noise from the fault you are describing.

[Briefs And Books]

Counterpoint: I would not order parts yet. The symptom still overlaps with a calibration/setup problem, and a new part can make the evidence worse.

This is where a cheap measurement beats another theory. Record the same test twice before and twice after the change.

I came here to save money and now I know what burr touch means. This has gone badly.

[Pipe And Punch]

I had a similar issue but not the same revision. Mine ended up being embarrassingly simple, so I would keep the easy checks alive until the evidence kills them.

I have nothing useful except sympathy and a strong suspicion the machine can smell fear. This forum is expensive.
