Travel moved something and I cannot find what

[Heat 74]

Machine / revision: Flair 58+ 2025
Country / voltage: Australia / 230V
Grinder / burrs / setting / calibration: Timemore Sculptor 064S; stock 64 mm flat burrs; 5 on the espresso range; zero point checked cold.
Basket / portafilter: 18–20 g VST-style precision basket; stock spouted portafilter (58 mm system where applicable).
Bean / roast date: Colombia Huila medium roast; roast date 2026-08-05.
Dose / yield / extraction time: 17.5 g in, 35 g out, 27 s target/current reference.
Water / temperature: RO water remineralized to about 70 ppm TDS; 94°C.
Exact symptom: Motor stalls or hesitates on dense light-roast beans at espresso fineness.
Tests already performed: Empty/clean the chamber, test a small dose at a slightly coarser setting and listen for normal startup Already cleaned the obvious removable parts and repeated the test once.
Diagnostic photograph or video: photo of the machine label/revision plus a short symptom clip.

I know “recalibrate it” is coming, so I did the basic calibration check first. What I cannot explain is this: Motor stalls or hesitates on dense light-roast beans at espresso fineness.

Confirmed solution: I disassembled only the user-serviceable parts, reseated them carefully and recalibrated. The abnormal noise/behavior disappeared without forcing the mechanism. I am leaving the original numbers above intact so the next person can see what changed.

[Briefs And Books]

Short answer: Start with the simple reproducible test before buying parts.
Applies to which model/revision: Flair 58+ 2025.
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.

The useful documented check is the revision-specific maintenance/service sequence, not a generic espresso-machine video. For Flair 58+ 2025, 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 Timemore Sculptor 064S / puck-prep side from the machine side instead of adjusting both together. Similar experience, not proof for your unit.

[Bean-Paste]

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.

This is a good example of why the exact revision and test history matter. “My Flair 58+ 2025 is bad” produces twenty theories; the measurements above at least give the theories somewhere to die.

If the answer is another $80 piece of metal I am going back to tea for twelve minutes
