New to the industry? Do you often panic when using a semi-automatic filling machine for the first time?
Clearly followed the instructions, but either no material comes out, the measurement is inaccurate, or even leakage occurs. Don’t worry!
This troubleshooting guide for semi-automatic filling machines is specifically written for beginners. It’s all short, plain English sentences. Each problem will explain the causes and solutions clearly—just follow the steps to avoid detours.
A quick tip first: When encountering a malfunction, don’t rush to disassemble the machine. First cut off the power and check basic issues. Most minor problems can be easily solved～
This is the most common problem for beginners. In most cases, the machine isn’t broken—you just haven’t checked a few basic links.
First check the raw materials: Is there enough material in the barrel? Is the material too thick and blocked at the feed inlet?
Then check the pipeline: Is the feed pipe inserted all the way to the bottom? Is there air trapped in the pipeline? You can open the exhaust valve to release air, or try manual suction.
Finally check the power supply: Is the power plug firmly inserted? Is the air compressor turned on? For pneumatic models, the air pressure needs to reach 0.4-0.6MPa to work normally. Insufficient pressure will also cause no discharge.
Pro tip for beginners: Before starting the machine every time, run it idly 3 times first. Confirm the machine operates normally before adding materials. This can reduce the occurrence of no-discharge issues.

What Causes Inaccurate Filling Measurement?
Inconsistent filling volume affects product quality and wastes materials. There are 3 core reasons—check them one by one.
First, incorrect parameter settings: Did you change the material before but not re-calibrate the filling volume? Follow the machine manual to reset the filling time or volume, then test fill 3-5 times with a beaker until the error is within the allowable range.
Second, residue at the discharge port: Material sticking to the discharge port will cause a little more filling next time. After each test filling, wipe the discharge port with a clean cloth, especially after filling viscous materials (such as sauce, cosmetic stock solution).
Third, changed material viscosity: The same machine requires different parameters for thin and viscous materials. If you change the material type, remember to adjust the filling speed—slow down for viscous materials to avoid measurement deviation.

How to Handle Leakage from Semi Automatic Filling Machine?
Leakage not only wastes materials but also dirties the operating table. Don’t rush to wipe it—find the leak first, then solve it.
The most common leak point is the sealing gasket: Check if the sealing gaskets at the discharge port and feed port are aged? Are there cracks or deformation? If yes, directly replace with a gasket of the same model and tighten the screws.
Second, loose connections: Check if the joints of the feed pipe and discharge pipe are loose? You can gently tighten them with a wrench, but don’t use too much force to avoid damaging the joints.
Another situation: Filling speed is too fast, causing material to splash and be mistaken for leakage. You can slow down the filling speed or adjust the height of the discharge port to make it close to the bottle body before filling.
Reminder for beginners: Develop the habit of checking the sealing gaskets once a week. Fix problems in time to reduce leakage failures.

Is Abnormal Noise Normal During Filling Machine Operation?
A normal semi-automatic filling machine only makes slight motor or air pressure noise during operation. If there are abnormal noises like “creaking” or “thumping”, there must be a problem.
First check for loose parts: Are the fixing screws and feed pipe buckles of the machine loose? If not tightened before starting, vibration will cause noise during operation. Check and tighten each one with a screwdriver.
Then check lubrication: Are the transmission parts (such as gears, guide rails) not lubricated? Lack of long-term lubrication will wear parts and cause abnormal noise. Add the corresponding lubricating oil according to the manual—don’t add too much.
Finally check for foreign objects: Did any material residues or small parts fall into the machine? First cut off the power, open the side cover of the machine, clean up the foreign objects, then run it idly.
Note: If abnormal noise is accompanied by severe machine vibration, stop using it immediately and contact the manufacturer for maintenance to avoid part damage.

How to Improve Slow Filling Speed?
Beginners always think slow speed affects efficiency, but you need to find the right way to increase speed—don’t adjust parameters blindly.
First check parameter settings: Is the filling time set too long? On the premise of ensuring accurate measurement, appropriately shorten the filling time to increase speed. But note that too fast speed will lead to inaccurate measurement or leakage.
Then check for pipeline blockage: Are the feed pipe or discharge pipe blocked by materials? Especially after filling materials with particles (such as jam, grain flour), the pipeline is prone to material accumulation. Remove it, clean it with clean water or corresponding solvent, then reinstall.
Finally check power supply: For pneumatic models, check if the air pressure is sufficient; for electric models, check if the voltage is stable. Insufficient air pressure or unstable voltage will slow down the filling speed—adjust to the standard range.
Suggestion for beginners: Don’t pursue the fastest speed at the beginning. First ensure filling quality, then adjust slowly after getting familiar.

How to Solve Severe Foaming During Filling?
When filling materials such as beverages, detergents, and cosmetic stock solutions, foaming is easy to occur, which not only affects measurement but also overflows. Beginners can try these 3 methods.
First, lower the discharge port height: Keep the discharge port close to the bottom of the bottle and let the material flow down along the bottle wall to reduce contact with air—this will significantly reduce foaming.
Second, slow down the filling speed: Fill in two times. Fill 80% of the volume first, pause for 1-2 seconds to let the foam dissipate, then fill the remaining 20%. This can effectively reduce foam.
Third, add defoamer: If the material itself is prone to foaming, you can add a small amount of corresponding defoamer on the premise of meeting production standards. But pay attention to the dosage to avoid affecting product quality.

Why Can’t the Semi-Automatic Filling Machine Start?
The machine has no response when pressing the start button. Beginners don’t think the machine is broken—first check these 4 basic points. 90% of the problems are here.
1. Power supply issue: Is the plug firmly inserted? Is there electricity in the socket? You can try another socket or check if the power switch is turned on.
2. Safety door not closed: Many semi-automatic filling machines have safety protection devices. The machine can’t start if the safety door isn’t tightly closed. Close the safety door again until you hear a “click” sound indicating it’s locked.
3. Emergency stop button not reset: If you pressed the emergency stop button before, the machine won’t start unless it’s reset. Find the red emergency stop button and rotate it clockwise to reset.
4. Low material protection: Some machines have a low material protection function. They will stop starting when the barrel is empty. Add materials first, then press the start button.

Essential Malfunction Prevention Tips for Beginners
In fact, many malfunctions can be prevented in advance. Beginners remember these 3 points to reduce 80% of troubles.
1. Before each use: Check the power supply, air pressure, pipeline connections, and sealing gasket status. Then run it idly 3 times. Confirm no problems before adding materials.
2. After each use: Clean the pipeline and discharge port in time, especially after filling viscous or corrosive materials. Avoid material residues blocking the pipeline and damaging the sealing gasket.
3. Regular maintenance: Check for loose screws and part lubrication once a week. Perform a comprehensive cleaning and calibration of the machine once a month.
Summary: When troubleshooting semi-automatic filling machine malfunctions, beginners should remember the principle of “first cut off power, first check basics, first solve simple problems”. Most minor issues can be fixed by yourself. If you encounter a malfunction that you really can’t handle (such as motor damage, circuit board failure), don’t disassemble the machine yourself—directly contact the manufacturer’s technical customer service.
