What Grinder Not Grinding means on your Dacor coffee machine (dacor coffee machine grinder not grinding)
A grinder that will not turn at all is distinct from one that runs but under-delivers grounds, and Dacor does not display any message that separates the two — an owner has to diagnose this one by listening and looking rather than reading a code. Silence when a brew is selected, with no grinding sound whatsoever, usually points to either an empty bean hopper or a stalled motor, while a motor that hums without turning suggests something is physically obstructing the burrs. Because the CM24 platform is discontinued, a grinder that has stopped turning is worth diagnosing carefully before assuming a full assembly replacement is needed, since the fix is sometimes far smaller than the part.

Symptoms
Read these against your coffee machine: they are what tells Grinder Not Grinding apart from the other things that can go wrong on a Dacor coffee machine.
- No grinding sound occurs at all when a brew cycle is started.
- A low humming or straining sound is audible, but the burrs do not appear to turn.
- The bean hopper is full, yet the machine still fails to dispense any ground coffee.
- The grinder starts, runs briefly, then stops abruptly partway through its cycle.
- A burning odor accompanies the attempt to grind before the machine cuts out.
Common causes
Any of the following can leave a Dacor coffee machine in this state, and telling them apart on the coffee machine decides whether a part is needed at all.
- Empty or near-empty bean hopper — the simplest cause, easily overlooked if beans have settled or clumped near the bottom.
- Foreign object jammed in the burrs — a small stone or debris mixed in with beans can physically stop the grinder.
- Stalled or failed grinder motor — years of use can wear the motor to the point it can no longer turn under load.
- Stripped or broken drive gears — the motor may run while the gears connecting it to the burrs no longer transmit motion.
- Oily bean residue caking the burrs — heavily oiled beans, such as dark roasts, can gum up the mechanism over time.
Troubleshooting steps you can try
Go down the list on your coffee machine and stop at the first step that makes you uneasy — a Dacor coffee machine is not worth an injury.
- Refill the bean hopper completely and confirm beans are flowing freely down toward the burrs.
- Power the machine off, and if safely accessible, check the hopper opening for any foreign object.
- Listen closely for a humming motor versus complete silence, since the two point to different causes.
- Avoid running the grinder repeatedly if a burning smell is present, to prevent further motor damage.
- Note whether the issue began after switching to an oilier bean, since residue buildup is a gradual cause.
Parts a technician may replace
A technician will work through the grinder motor, bean hopper, burr assembly, and grinder drive gears on your coffee machine. Genuine OEM or trusted-supplier parts are matched to the coffee machine by model and serial number rather than fitted to a coffee machine on spec.
When to call a technician
A motor that hums without turning, or one that is completely silent with a full hopper, needs a technician to open the grinder assembly rather than continued attempts to force a cycle. There is no urgency at Medium severity, yet a coffee machine that repeats Grinder Not Grinding after these checks deserves a technician’s eyes. Repairs to your coffee machine are carried out by independent technicians using genuine parts, with 30 days of labor cover.
