When to replace espresso grinder burrs
Burrs dull slowly, so you rarely notice the day grind quality dips — you notice fluffy, inconsistent grounds and shots that will not dial in. Replacement intervals depend on burr type and how many kilos have passed through.
What you need
- New burrs (flat or conical, model-specific)
- Screwdriver set
- Compressed air or dry brush
- Paper for chirp test (optional)
How to do it
- Mark the position of the adjustment ring so you can return to it
- Disassemble the top burr carrier
- Remove the old burrs (mind the fastening, usually 2–3 screws)
- Clean the seats with compressed air or a dry brush
- Install the new burrs centered and tighten to spec
- Calibrate to zero point (chirp test or paper test)
- Test with an espresso shot and adjust the grind setting
Tips from the bench
Collected from manufacturer guidance and years of home-barista forum wisdom:
- Photograph the shim and washer stack under the old burrs. Those shims are your factory alignment; losing their order costs taste.
- Tighten the new burr screws gradually in a cross pattern, like a car wheel. Uneven torque means uneven wear from day one.
- Expect a full re-dial: new burrs grind differently at the same setting. Note the old setting as a reference, not a target.
HEADS UP
After replacement, recalibration is required. Your old grind setting won't be 1-to-1 anymore. Start coarser and work finer.
