Most automatic salt and pepper shakers open by twisting the body or base to an unlock mark, then lifting the top to fill the chamber with whole peppercorns or coarse salt.
A grinder that won’t budge usually isn’t broken — it’s locked at the seam, and one wrong twist in the wrong direction keeps the lid sealed tight. The steps below follow the manufacturer manuals for three popular models, plus the general pattern that covers the rest.
How Do You Open An Automatic Grinder?
Twist one half against the other until the unlock icon lines up with the lock icon, then lift the top straight off. Which half moves depends on the model.
On most electronic mills, you hold the lower section and turn the upper body to the left until the markers align. Some units reverse that — you grip the glass base and turn the stainless base counterclockwise instead. If the body won’t turn, stop; forcing it can crack the housing. Check the seam for a small unlock symbol and match the direction to it.
A few designs skip the twist entirely. The LARS NYSØM electric grinder set opens with a sliding side panel that pops up and clicks back into place.
Step-By-Step Refill For Specific Models
Each brand hides its refill opening in a different spot, so the exact move matters. Here is how the three most common designs work.
ZWILLING Enfinigy Electric Mill
Hold the top section steady and twist the base counterclockwise to unlock. Separate the base from the body, load your spices into the chamber, then twist the base clockwise to lock it back on. ZWILLING’s own manual lists this as the full sequence.
OXO Good Grips 2-in-1 Grinder & Shaker
This one has two chambers, so refilling depends on what you’re adding. For salt, unscrew the stainless steel cap and pour salt into the upper chamber. For peppercorns, pull the entire salt chamber straight up, add whole peppercorns to the lower chamber, then press the chamber back down until it clicks.
Sliding-Panel Grinders
Models like the LARS NYSØM set use a side panel instead of a twist. Slide the panel open, pour in whole spices, and slide it back up until it clicks shut.
Whatever the mechanism, the refill itself is the same job: separate the chamber, add whole spices, reseal. A small funnel keeps the pour clean and cuts spills.
What Should You Put In — And How Much?
Use whole peppercorns in pepper mills and coarse or granulated salt in salt mills. Never load pre-ground pepper or fine salt into a mill built for whole spices, because finer grains clog the grinding mechanism.
Don’t fill the chamber to the brim. Most manufacturers suggest leaving room for the spices to move — . Overfilling jams the grinder and stops the halves from seating properly when you close it.
Once you know the pattern, choosing a grinder is mostly about which refill design you’d rather live with — our tested picks are ranked in this roundup of the best auto salt and pepper shakers.
- Turn the unit off and pull the batteries before refilling, so it can’t activate mid-pour.
- Keep seasoning out of the battery compartment and motor area.
- Refill only with dry spices, since moisture causes clumping and jams.
- Line up the unlock and lock markers before you close, and seat the chamber until it clicks.
The ZWILLING counterclockwise twist and the OXO pull-up chamber both confirm the same rule: the chamber must seat fully. If it won’t lock, the grind setting or an overfilled chamber is usually the cause — empty a little out and try again.
FAQs
Why won’t my electric grinder twist open?
You are likely turning the wrong half or the wrong direction. Hold the lower section and rotate the upper body left until the unlock icon lines up with the lock icon. If it still won’t move, check for a sliding panel instead of a twist mechanism before applying any force.
Can I put regular table salt in a salt mill?
No. Table salt is too fine and absorbs moisture, which clogs the grinding mechanism. Use coarse or granulated salt, the grade most electric salt mills are built to handle. The same rule applies to pepper: whole peppercorns only, never pre-ground.
How full should I fill the chamber?
Leave headroom. Fill to roughly three-quarters to 85% full, depending on your manual, so the spices can move freely. An overfilled chamber jams the grinder and can stop the halves from locking together when you reassemble the unit.
