A commercial grinder record should answer a practical question: what changed, on which machine, under which coffee and workflow? A burr replacement date by itself is not enough. The useful history connects the grinder identity to the burr, setting, dose, output, cleaning, alignment observation, and later symptom.
The coffee service hub provides the equipment context. Keep the record model-specific and avoid a universal burr-life number. Grinder use, burr design, coffee, setting, and manufacturer guidance all matter.
Identify the grinder and burr
Record the grinder make, model, serial, asset tag, location, burr type or part identification when documented, and the date the record starts. If there are multiple grinders, label them by station and function. Do not remove a cover solely to find a number.
Attach the manufacturer’s burr and cleaning instructions. Note the person or company that completed an inspection or change. Keep the prior burr information when available instead of replacing it with a general label such as “standard burr.”
Record the operating setting
Write down the coffee, roast or lot record used by the café, grind setting, dose method, timer or control mode, and the output observation. Note if the grinder is used for one beverage or several. If the setting changes, record the old and new positions.
Record retention, clumping, dose drift, grind distribution, motor sound, jams, and the time of day. Use the café’s normal shot or brew record. Do not assign a failed burr or motor from a change in output.
Document cleaning and alignment observations
Record the model-authorized cleaning procedure, product, date, and result. Do not invent an interval or use compressed air, liquid, or a brush where the manufacturer does not permit it. State if a cleaning step could not be completed.
For alignment, record only what a documented procedure or qualified inspection established. A grind pattern or output change can be a clue, but it is not a complete alignment test. Do not loosen a carrier, move a collar, or reach into burrs to create a before-and-after comparison.
If a technician leaves a measurement, part description, or recommendation, attach it to the machine record. Keep a recommendation separate from a completed change.
Decide when a review is needed
Review the record when the setting moves unexpectedly, the dose changes, the grinder stalls, a new sound appears, the output becomes inconsistent, retention returns after a documented cleaning, or a burr change does not resolve the pattern. These signals can involve coffee, workflow, controls, alignment, drive components, or another condition.
Do not set a replacement date from an online rule that does not match the grinder. Use the model documentation and the actual operating history. A record supports a decision; it does not ensure a result or prevent future symptoms.
Keep staff safe
Staff can log settings, coffee, output, cleaning, and visible behavior under the normal procedure. Internal burr, motor, wiring, control, and alignment work needs qualified service. Stop for a jam, burning smell, smoke, damaged wiring, power trip, or unusual heat. Do not keep cycling a jammed grinder or bypass a guard.
Send the history with the request
Provide the model, serial and asset tag, burr identity, change or inspection history, coffee, setting, dose, output, cleaning, alignment notes, alarms, sounds, jams, photos taken safely, and access details. The coffee equipment FAQ can answer process questions. The coffee blog gives related operator context, and the contact page can receive the record.
Coffee equipment uses a pickup-and-return bench repair model. The deposit is $150 for standard machines such as Breville, DeLonghi, Gaggia, Rancilio, Lelit, Rocket, ECM, and Profitec; $175 for Jura and Miele super-automatics and home La Marzocco machines; and $250-550 for commercial La Marzocco machines. It includes pickup, diagnosis, and return delivery, but it is not credited toward repair. We do not quote repair prices by phone. A written estimate follows diagnosis and comes before repair work. Coffee repair warranty terms are 6 months on parts and labor and 90 days on consumables. The service area covers 56 cities outside Marin County, plus San Francisco for coffee equipment only.
A good burr record does not predict a universal replacement date. It connects the machine, burr, coffee, settings, work history, and observed output so the next decision is based on the actual grinder.
Keep the record useful after a change
After a burr inspection or change, record the new identity, setting, coffee, dose, output, and operator observation. Note what was adjusted and what was left unchanged. If the original retention, clumping, sound, or dose symptom remains, preserve that fact instead of describing the work as a complete fix.
If a grinder is moved to another station, carry the asset record with it and add the new water, power, coffee, and workflow context. A burr result from one station may not explain a result at another. Keep the old location and date visible.
A qualified service record should identify any measured alignment, drive, control, or electrical finding. Staff records can provide the before-and-after operating behavior, but they should not fill in an internal finding from a visual guess.
Compare output without changing everything
When a burr record is reviewed, hold the coffee, dose method, and normal workflow steady long enough to describe the output. Record the setting, particle or dose observation used by the café, retention, sound, and shot or brew result. If the operator changes a setting to keep service moving, log the change instead of treating the later result as a clean comparison.
A burr change may alter the setting needed for the café’s recipe. That is an operating observation, not proof that the new burr is defective or that the old burr was beyond use. Keep the qualified work note and the operator result together.
If the grinder is noisy, hot, jammed, electrically abnormal, or damaged, stop the normal workflow and use the site’s safety process. Do not make the grinder record a reason to reach into the burr area.
