To unclog a meat grinder, reverse the auger direction if your model has a reverse function, then disassemble and manually remove the blockage. If reverse isn’t available, unplug the grinder, take it apart, and extract the jammed material from the cutting plate and knife. A clog usually happens when meat fibers, sinew, or fat wrap around the auger or block the plate holes, so clearing those parts is the first step. Knowing how to unclog a meat grinder correctly prevents damage to the motor and blades.
Overloading the Grinder
Stuffing too much meat into the hopper at once is the most common cause of a clog. The auger can’t pull the meat through fast enough, and the pressure forces fibers into the plate holes, creating a solid plug. You might notice the motor slowing down or stopping completely.
Always feed meat in small, consistent chunks. Let the grinder work at its own pace rather than using the stomper to force pieces down. If you hear the motor laboring, stop feeding and let it clear before adding more.
Large Chunks of Meat or Hard Gristle
Pieces that are too big for the auger housing can stall the mechanism. Similarly, hard gristle, tendons, or bone fragments can jam between the knife and plate, preventing rotation. Even a single large piece can bring the whole process to a halt.
Cut meat into strips that fit the feed tube diameter (about 1 to 2 inches wide). Trim off visible gristle and sinew before grinding. If you hit a hard piece, stop immediately and clear it rather than forcing it through.
Too Little Fat or Incorrect Fat Ratio
Lean meat without enough fat can be dry and fibrous, causing it to cling to the auger and plate. Fat acts as a lubricant, helping the meat slide through smoothly. A mix with less than 10% fat is prone to clogs, especially in smaller grinders.
If you’re grinding very lean cuts like sirloin or venison, add a small amount of pork fat or suet (about 15-20% by weight) to aid flow. Chilling the meat and grinder parts before use also reduces friction.
Wrong Plate Size or Dull Blades
Using a plate with very small holes (like 3mm or 4.5mm) for coarse meat can cause frequent clogs. The small holes struggle to handle fibrous meat, and the knife may not cut cleanly if it’s dull. A dull knife tears meat instead of slicing it, creating a paste that blocks the plate.
Match the plate size to the meat type: coarse plates (8mm+) for tougher cuts, fine plates for emulsified mixtures. Sharpen the knife regularly with a fine stone, and replace it as soon as it feels dull.
Improper Assembly or Loose Parts
If the auger, knife, or plate isn’t seated correctly, the grinder can jam. A loose ring nut may allow the plate to shift, misaligning the cutting surfaces. This can cause meat to back up inside the housing instead of moving forward.
When reassembling, tighten the ring nut firmly but not with excessive force. Ensure the knife sits flat against the plate and the auger locks into the drive shaft. A quick test run without meat can reveal if the parts are aligned.
Dirty or Clogged Plate Holes
Residual meat from a previous session can dry and harden inside the plate holes, reducing the opening size. When you start grinding again, the fresh meat packs against the dried bits, causing a jam. This is especially common if you don’t clean the plate thoroughly after each use.
Always disassemble and wash every part immediately after grinding. Use a small brush or toothpick to remove any meat fragments from the plate holes. Soak stubborn residue in warm soapy water before scrubbing.
How to Fix a Clogged Meat Grinder
- Unplug the grinder and disassemble the head to access the blockage.
- Remove the ring nut, plate, knife, and auger, then pull out any jammed meat with your fingers or tweezers.
- Soak the plate and knife in warm water to loosen dried meat, then scrub the holes with a brush.
- If the clog is inside the housing, insert a long screwdriver or chopstick to gently push the material out from the auger side.
- Reassemble the grinder, ensuring all parts are clean and properly aligned.
- Feed smaller, well-trimmed pieces of meat gradually, adding fat if needed.
If clogging persists despite following these steps, the issue may be with the grinder’s motor or internal components. For more troubleshooting tips on kitchen appliances, you can explore our blog for related guides.

Frequently Asked Questions
Can I use reverse to unclog a meat grinder?
Many electric meat grinders have a reverse button that spins the auger backward to dislodge jams. If yours does, hold the reverse for a few seconds, then switch back to forward. Repeat if needed. Never force reverse if the motor doesn’t respond.
Why does my meat grinder keep clogging with the same meat?
If the same type of meat clogs repeatedly, the issue is likely the fat ratio or the plate size. Lean meat needs more fat or a coarser plate. Also check that the blade is sharp and the plate holes are clean. Sometimes the grinder itself is undersized for the volume.
Should I oil the meat grinder before use?
Some manufacturers recommend a light coat of food-grade mineral oil on the auger and plate to reduce friction. Check your manual. If you oil, do so sparingly and wipe off excess. Oiling does not replace proper meat-to-fat ratios.
Can a clogged meat grinder damage the motor?
Yes, repeated clogs or forcing the grinder through a jam can overheat the motor or strip the gear teeth. Always stop the machine immediately if it stalls. Let it cool for 15 minutes before attempting to clear the clog.
How often should I sharpen the meat grinder blade?
Sharpen the blade after every 50 to 75 pounds of meat, or whenever you notice tearing rather than clean cutting. Dull blades cause more clogs and produce a pasty texture. Replace the blade if it’s chipped or worn unevenly.
