Fault: "Vessel Overtemp." What should I do?

The vessel temperature has exceeded the maximum limit.

Possible Causes:

(1) The solution level is low in the vessel, but the level sensor is indicating full. The level sensor has two main components that work together. These components are a Level Sensor Module and the Glass Sensor Tip. Refer to DELTA Service Procedure Analog Level Sensor Cleaning and Testing (DES007). 

(2) If the level sensor is not working, it may need replacing. Refer to DELTA Service Procedure Level Sensor Analog Cable and Glass Tip Replacement (DES009) to replace the Analog Level Sensor Glass Tip and Fiber Optic Cable (Part #: A32).

(3) The vessel is overfilled with the solution. The Level Sensor is not detecting the solution. Refer to DELTA Service Procedure Analog Level Sensor Cleaning and Testing (DES007).

(4) The motor stopped turning. Check the Packing Nut to make sure it is not over-tightened. Refer to DELTA Service Procedure Agitator Packing Maintenance and Nut Adjustment (DES001).

(5) The motor needs to be replaced. Refer to DELTA Service Procedure Motor Assembly Replacement (DES023).
