      If your L&R Cleaning Equipment cleaner will not start, make sure it is plugged into a functioning electrical outlet. Also, turn the timer clockwise and ensure the rear power switch is ON. If the fuse is blown, call an authorized service center.

    Why is there decreased ultrasonic activity in my L&R Quantrex Q310?

      If your L&R Cleaning Equipment shows decreased ultrasonic activity, ensure the tank was filled with warm tap water plus cleaning solution and has run for 5 to 10 minutes to degas the solution. Also, change the solution if it's dirty. Adjust the solution level to one inch from the top of the tank with the load. Clean the tank with warm water and a non-abrasive cloth if the tank bottom is covered with soil particles. Don't use de-ionized water, as it does not cavitate as well as ultrasonic solutions.

      If your L&R Cleaning Equipment operates but does not heat the solution, first, ensure the heat switch is turned ON. If the issue persists, the heater may have malfunctioned, and you should call an authorized service center.
