A Cuisinart Grind and Brew that hums, brews, but never grinds has one of four problems: the grind-off setting is engaged, a lid or basket interlock is not fully closed, the grinder chute is packed with oily coffee dust, or the grinder motor itself has quit. The first three cost nothing to fix and cover most machines that arrive at this page.
Grind failures in order of likelihood
| Check | What is happening | Fix |
|---|---|---|
| Grind off button | Machine set to brew pre-ground, by design | Toggle grind back on; the setting persists between brews |
| Lid and basket interlocks | Any misaligned lid tells the grinder not to start | Reseat hopper lid, grinder lid, and filter basket until they click |
| Chute clog | Oily bean dust cakes the path from grinder to basket | Unplug, empty, brush out the grinder chamber and chute |
| Damp beans or flavored beans | Oils and moisture paste the burrs and chute | Switch to dry medium roasts; clean after oily batches |
| Grinder motor | Click or silence with all interlocks correct and clean | Motor or switch failure; weigh repair against replacement |
Interlocks are the silent killer
These machines refuse to grind if the hopper lid, grinder basket, or filter door sits a few degrees off. That is a safety feature behaving correctly. After every wash, reseat each piece until it clicks and try again. The pattern to notice: grinder stopped working the same day you cleaned it. That correlation is the interlock, not a coincidence.
Oily beans and grind-and-brew machines do not mix
Dark oily roasts shed a paste of oil and fines that cakes the narrow chute between grinder and brew basket. The machine still grinds into a blocked chute, then brews weak or overflows, and eventually the packed chute stalls the burrs entirely. Run dry medium roasts, and brush the grinder chamber weekly if you insist on shiny beans. If the coffee has gone weak rather than absent, the chute is partially blocked and cleaning fixes it.
Brew side still works, and that is your answer
Because grinding and brewing are separate systems, a healthy brew cycle with pre-ground coffee proves the machine is worth keeping while you fix the grinder. If the burrs are truly dead outside warranty, you can also just run it as a normal drip machine with pre-ground and a separate grinder, which many owners quietly prefer; see best coffee makers with grinders for whether built-in grinding is worth it at all, and Cuisinart not brewing if the brew side fails too.

FAQ
Why does my Cuisinart Grind and Brew brew but not grind? Check the grind-off setting first, then the lid and basket interlocks, then a chute clogged with oily bean residue. All three are free fixes; a dead grinder motor is the rare fourth case.
Why did my Grind and Brew stop grinding after I cleaned it? A lid or basket is reseated slightly wrong and the safety interlock is preventing the grinder from starting. Reseat the hopper lid, grinder lid, and basket until each clicks into place.
Can I use pre-ground coffee if the grinder is broken? Yes. Set the machine to grind off and it runs as a normal drip brewer, which is a reasonable permanent workaround with a separate grinder.
