How to quickly troubleshoot coffee powder mixing machine failures?
Jul 30, 2025
1. Motor failures:
If the equipment cannot start, first check whether the power socket is powered, whether the fuse is blown, and whether the wires are damaged. If the power supply is normal but it does not run, it may be that the motor overheat protection is activated. You need to wait for 30 minutes and try again; if it still does not work, it may be that the motor carbon brush is worn, and you need to disassemble the motor and replace the same type of carbon brush. The motor makes abnormal noises during operation, mostly because the bearing is short of oil. You can inject special lubricating oil. If the abnormal noise continues, you need to replace the bearing.
2. Stirring system failure:
The stirring paddle speed slows down or freezes. First, stop the machine to check whether there is any foreign matter stuck in the paddle. If it is still abnormal after cleaning, it may be that the transmission belt is loose. Adjust the belt tension. If the paddle does not rotate, it may be a gearbox failure. You need to check the gear wear. If it is serious, you need to replace the gear set.

3. Control system failure:
The control panel has no display. Check the power connection and display cable. If they are loose, re-plug them; if there is still no response, it may be that the control panel is damaged and a new panel needs to be replaced. If the device does not execute after setting the parameters, it is mostly due to program disorder. Press and hold the reset button to restore the factory settings and try again, or contact the manufacturer to update the system.
4. Unloading and loading failures:
The unloading port is blocked. Clean the residual coffee powder and check whether the valve is stuck. Apply food-grade grease; unsmooth loading may be due to insufficient tilt angle of the hopper. Adjust the height of the bracket, or there are lumps in the pipe. Use compressed air to clear it.
Be sure to turn off the power when troubleshooting. Repairs involving circuits or mechanical core components must be handled by professionals to avoid self-disassembly and secondary damage.
