Possible Causes:
When the start button is pushed, the computer tells the appropriate valve to open and allow flow from the cubetainer into the vessel. If liquid is manually poured into the Vessel before the computer communicates with the appropriate valve, this fault screen will appear. Open the vessel, if the vessel is full Press "Y<ENTER>" to continue the run. If the vessel is not full, the level sensor may not be functioning properly. See A2000 Service Procedure10 for SICK Level Sensor (Blue Model) or see A2000 Service Procedure 7 for Analog Level Sensor (Black Model).
