Technical Maintenance Series
Protecting the heart of your ultrasonic cleaning system for long-term performance.
The transducers are the most critical components of your LeelaSonic machine. They convert electrical energy into high-frequency mechanical vibrations. Regular maintenance ensures consistent cleaning power and prevents expensive tank repairs.
NEVER turn on the ultrasonic power if the tank is empty.
Operating the machine without liquid (dry running) can cause the transducers to overheat and decouple from the tank base. Always ensure the liquid level is at least 2/3rds full or reaches the designated level marker.
Whenever you change the cleaning chemical or refill the water, you must degas the liquid. Fresh water contains dissolved air bubbles that absorb ultrasonic energy, reducing cleaning efficiency. Run the machine for 5-10 minutes before adding your parts to remove these bubbles.
Heavy contaminants, metal chips, or thick sludge should not be allowed to settle on the bottom of the tank. This layer acts as a "damper," absorbing the vibrations before they reach the liquid.
Tip: Use the built-in drainage system weekly to flush out sediment.
Over several years, the stainless steel surface directly above the transducers may show signs of pitting (cavitation erosion). Using the correct chemical pH and avoiding over-temperature settings (keeping it below 80�C) will significantly slow down this natural wear process.
