How do I know the burrs are worn out?

Shots taste flat or sour and will not dial in, the grind looks uneven, or the recipe keeps drifting no matter how often you adjust. Worn burrs make a wide, uneven grind that channels. Fresh burrs bring back a clean, even grind and the espresso comes back with it.

Do you service grinders built into bean-to-cup machines?

Yes. Grinders inside super-automatics from Jura, WMF, Schaerer, Eversys, and Franke, plus standalone espresso grinders and batch shop grinders. We provide Franke authorized service with A-Line technical certification, so those built-in grinders get factory-level service.

What does grinder repair cost?

The bench deposit covers pickup, diagnosis, and return and is not credited toward the repair. We confirm the deposit when the equipment is scheduled, then quote parts and repair labor after bench diagnosis. Coffee repairs carry 6 months on parts and labor.

My grinder is making a loud metal-on-metal noise. Keep using it?

No. Stop and call. That noise is usually a chipped burr, debris, or a rock in the beans, and running it can turn one cheap repair into real damage.

What we do. What we fix.

A grinder fault shows up in the cup first

A grinder may still run while the dose wanders, the grind changes between cycles, or the motor labors under beans. Other faults are less subtle: a jam, a dead display, a breaker trip, or a machine that starts but will not feed coffee. We diagnose standalone and machine-integrated grinders on the bench, where we can test them repeatedly without disrupting a counter.

Franke A-Line machines are diagnosed on site at their installed water and drain connections: A400 $150, A800 $200, A1000 $250; repair work is quoted afterward.

We start by reproducing the complaint. Then we inspect the grind path, burr condition, drive, dosing hardware, wiring, and controls that apply to that unit. Cleaning can solve a packed grind path, but it cannot restore a worn part or a motor that fails under load. We separate those cases before quoting work.

What we cover

Espresso grinders (on-demand and doser)
Batch and bulk shop grinders
Grinders built into bean-to-cup and super-automatic machines
Burr replacement and alignment
Dose and timing calibration
Motor, capacitor, and switch repair
Adjustment collars and stepless mechanisms
Hopper, chute, and anti-static issues

Symptoms we see all the time

Shots taste flat or sour and won’t dial in. Burrs are worn past their life. Fresh burrs bring back a clean, even grind and the espresso comes back with it.

Dose is inconsistent cup to cup. Timer drifting, a worn dosing mechanism, or static throwing grounds where they shouldn’t go.

Grinder is slow or bogs down. Tired motor, a failing start capacitor, or grounds packed into the chute.

Won’t start, or hums and quits. Switch, capacitor, or motor. We test which before replacing anything.

Grind keeps changing on its own. Adjustment collar slipping or worn. Common on busy grinders that get bumped all day.

Loud, rattling, or metal-on-metal. Burr chips, debris, or a rock in the beans. Stop using it and call us before it does real damage.

When to replace burrs

Burrs are a wear part. Espresso burrs at high volume typically run a few hundred to a thousand-plus pounds before the edges dull enough to hurt the cup. If your shots have slowly gotten worse and no machine adjustment fixes it, the burrs are usually the answer. We’ll measure the wear and tell you straight whether it’s time, not just sell you a set.

How pickup works

The bench deposit covers pickup, diagnosis, and return and does not go toward the repair. We confirm the applicable deposit when the equipment is scheduled because it depends on the equipment and brand tier. Standard bench time is $150 per hour; Jura, La Marzocco, and Miele bench time is $175 per hour.

After diagnosis, we send a written quote and wait for approval. Diagnostics can take up to a week; most repairs run 3–4 weeks. That is exactly why we recommend preventive maintenance. Keeping the grind path clean and addressing drift early is easier than finding the grinder stopped at opening.

6 months on parts and labor; 90 days on consumables. Coffee pickup includes our 65 Bay Area cities plus San Francisco.

Brands we service

Mazzer, Mahlkonig, Anfim, Nuova Simonelli, Fiorenzato, Compak, Bunn, and the grinders inside Franke and other bean-to-cup machines. As a Franke authorized service company with A-Line technical certification, we handle their integrated grinders to factory spec. Parts for Astoria, CMA, and Wega grinders come through our RCW distributor partner. If a burr swap and a cleanup will save your grinder, that’s what we’ll do.

Our flagship covers the service; our dedicated coffee division has the coffee-only intake. You can also contact Adrium or call (925) 999-4095.
