Maintenance and  repair  

6.1  

Maintenance  

SONOREX ultrasonic baths require no maintenance.
For purposes of regular control, the following functional checks may be carried out.

6.2 

Functional checks  

Check the LEDs

A test routine can be started for an internal  function check:
The ultrasonic bath must be switched off for this. When the  Start/ Stop button is kept held down, 
the ultrasonic bath is switched on with the ON/OFF button. 
All LEDs light up after each other for a 1/3 second. The last set values are then displayed. 
The test is then successfully completed.
If there are any deviations, the ultrasonic bath must be sent in for checking/ repairs.

Monitoring the ultrasound

Function can be checked using a standard wattmeter. It is to be inserted between the ultrasonic 
bath's mains plug and the socket. 
•  Fill the oscillating tank with  

fl

 uid, see Section 4.1.

•  

Switch ultrasound on: Next, the value displayed is to be compared with the corresponding value 
in the technical data (Section 1.4) (tolerances ± 20%). 

 Checking the ultrasound effect

For monitoring, we recommend the performance of a foil test (biannually).
A suitable frame for the foil test can be requested from the manufacturer. Customary aluminium foil 
is used to conduct the test. Next, a comparison is made with previously-generated foils. 
For more detailed information, please see the appendix. 

A measurement procedure is described in DIN SPEC 40170:2013-11 (Measurement and 
evaluation of cavitation noise).

6.3 

Error analysis  

SONOREX ultrasonic baths are robustly constructed and designed for a high level of reliability. 
Nevertheless, the possibility of a malfunction due to a  defective component can never be fully 
discounted. 
The following overview of possible sources of error should serve as an aid for error detection and 
elimination.



Ultrasonic bath oscillates weakly, unevenly or noise is too loud:
-   Has 

fl

 uid been properly degassed?

-  Is it overloaded with objects to be treated?
-  Uneven noises (wobbling) 





Treat for 10 min.
Remove a few parts.
No error – slightly adjust the  

fi

 lling 

level of the 

fl

 uid.



Slight erosion visible on the bottom of the bath?



Natural wear.
Ultrasonic bath OK.

 Any malfunctions are to be communicated in writing to the manufacturer.
