  If you're experiencing poor cleaning action with your ALKOTA Ultrasonic Jewelry Cleaner, several factors could be the cause. It could be due to hard water; in this case, connect the machine to a water softener. Another reason might be an improper chemical or chemical mixture. Make sure you obtain the correct chemical and mix the chemicals per the label, following all mixing, handling, application, and disposal instructions. For low pressure, or if little to no chemical is being drawn, consult the sections addressing these specific issues. Also, check for low discharge pressure following the instructions for correcting low operating pressure.

  If your ALKOTA Ultrasonic Jewelry Cleaner isn't drawing chemical, first, ensure you have an adequate supply of chemical solution and replenish if necessary. Check that the metering valve is open by turning the knob. Inspect the chemical line strainer for clogs and clean it if needed. Also, make sure there are no air leaks in the chemical line; tighten all fittings and hoses. Finally, examine the restrictor orifice; if it's too large or missing, disassemble and clean, then install the proper size orifice.

  Matthew WuAug 26, 2025
  If the pump motor of your ALKOTA Ultrasonic Jewelry Cleaner won't start and doesn't hum, the issue might be due to a lack of power. Try using a different outlet and check the fuses in the main disconnect switch, replacing any blown fuses. If power isn't the issue, the motor starter or ON/OFF switch might be defective, in which case you should call a service technician. It could also be a defective motor, requiring you to call a service technician or take the motor to a repair/warranty station.

  If the pump motor of your ALKOTA Ultrasonic Jewelry Cleaner starts slowly, overheats, and then stops, it could be due to low voltage. You can check the section about 'Low voltage'. Alternatively, there might be excessive back pressure, which is discussed in the 'Excessive Back Pressure' section. Finally, the motor itself could be defective, requiring you to call a service technician or take the motor to a repair/warranty station.

  Excessive or unusual noise in your ALKOTA Ultrasonic Jewelry Cleaner could indicate a defective pump. Alternatively, the motor might be defective, requiring you to call a service technician or take the engine to a repair/warranty station. Noises could also arise from pulleys rubbing (adjust shields or pulley(s)) or misalignment of the pump and motor (realign pump and engine).

Why does the ALKOTA 3102 pump motor stop and not start?
- A
  Amanda GonzalezSep 7, 2025
  If the pump motor of your ALKOTA Ultrasonic Jewelry Cleaner stops and won't restart, the motor starter might have 'kicked out' (if equipped) or the thermal overload tripped. Try turning the motor starter off to reset it, then turn it back on, or push the thermal overload reset button on the motor. Excessive back pressure could also be the cause. Lastly, the motor itself could be defective, requiring you to call a service technician or take the motor to a repair/warranty station.
