How to Fix a Pepper Grinder: A Troubleshooting Guide
A troubleshooting map for a misbehaving mill — won't grind, too fine, too coarse, a stuck top, or clumped seasoning — pointing you to the exact fix for each.

Almost every “broken” grinder is one of a few simple faults. Match your symptom below and follow the link to the full fix.
Symptom → cause → fix
| Symptom | Likely cause | Go to |
|---|---|---|
| Turns but nothing comes out | Empty, or pinched too fine | Not working |
| Only fine powder | Nut too tight | Grinds too fine |
| Only coarse chunks | Nut too loose | Too coarse |
| Salt mill seized | Damp clumping | Salt grinder stuck |
| Top won’t turn | Salt-stuck or sealed | Top won’t unscrew |
| Dust at every setting | Worn burr | When to replace |
The 60-second routine
Most mills come back to life like this:
- Is it empty? Refill to four-fifths — the refill guide has the routine.
- Adjust the nut. Dust → loosen; chunks → tighten. See coarseness.
- Unclog it. Grind a spoonful of dry white rice through to scrub the core, then clean the wood and refill dry.
- Still nothing? Check whether the mechanism has worn out, or whether it was a sealed disposable all along.
If a cheap mill fails every test, a refillable ceramic set is the cure — our best manual grinders are built to be fixed, not thrown away.
Frequently asked questions
Most often it's empty or set so fine the rotor is pinched shut. Check the chamber, then loosen the top nut half a turn. Damp clumping and a worn burr are the next suspects.
Empty it, let any damp seasoning dry, then grind a spoonful of dry white rice through the mill. The rice scrubs the burr and absorbs oils; brush out the residue and refill dry.
A refillable one, yes — nearly every fault is adjustment, clumping, or an empty chamber. Sealed supermarket grinders are glued shut and can't be fixed.
When it grinds only powder at every setting despite being full and correctly adjusted — the burr has worn out. Ceramic mills rarely reach that point.
