What we do. What we fix.

The grinder decides the cup before the machine ever touches it

You can have a perfect espresso machine and still pull bad shots if the grinder’s off. Worn burrs make a wide, uneven grind that channels and tastes flat. A drifting adjustment turns a dialed-in recipe into a moving target. A dosing fault costs you beans every single cup, which adds up fast at volume. Grinders get less attention than the espresso machine and break just as often.

We repair and service commercial coffee and espresso grinders for cafes, roasters, restaurants, and offices across the Tri-Valley and East Bay.

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 and bench service work

Give us the make and model and what the grinder’s doing. We pick it up, diagnose it on the bench, and bring it back. The deposit starts at $150, includes pickup and return, and is not credited toward the repair. Extra bench time is $150 per hour. Diagnostics can take up to a week; most repairs run three to four weeks. We calibrate dose and grind before return so you are not left to re-dial it yourself.

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 Coffee Systems certified technician on the A-Line super-automatics, we handle their integrated grinders to factory spec. Parts for Astoria, CMA, and Wega grinders come through our RCW distributor partner.

We’re independent. If a burr swap and a cleanup will save your grinder, that’s what we’ll do.

Honest repair timing

A repair queue is easier to avoid than to rush.

We pick up the machine, diagnose it on the bench, and return it. Pickup and return are included, and you get the repair quote after diagnosis.

Diagnostics can take up to a week; most repairs run 3–4 weeks. That is exactly why we recommend preventive maintenance. A maintained machine does not sit in a repair queue for a month.

  • Diagnostics: up to one week
  • Most repairs: 3–4 weeks

What do customers ask about Commercial Coffee Grinder Repair?

  • 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 are Franke certified on the A-Line, so those built-in grinders get factory-level service.
  • What does grinder repair cost?
    Pickup, bench diagnosis, and return deposits start at $150. Jura, Miele, and home La Marzocco machines are $175; commercial La Marzocco equipment is $250–$550. The deposit is not credited toward the repair. We quote parts and repair labor after bench diagnosis. 6 months on parts and 90 days on consumables.
  • 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.
