The chiller is giving error E9, from what I checked according to the label pasted on the chiller, it says that it is the liquid level (water).  
However, I already carried out the emptying and put a new deionized water. The level display is ok and the error still persists. Does anyone know what can be done?

You can try it.  
In standby mode, press and hold the menu button until the screen displays “Cod” and then let go.  
Then enter the password 359 and press the confirm key.  
Press the menu key to switch to the P26 parameter, press the “up” key to change 0 to 1, and press confirm to exit.

Which of the buttons hold to appear the “cod”?
