You are relying on software UI to tell you if hardware is dead?
Have you checked the pump by listening to it or feeling the tubing? Do either vibrate?
Tap the pump top rather vigorously and tap both coolant lines, see if that dislodges any air bubbles.
HOWEVER - if you do not feel vibration, it is possible the pump isn't spinning. Can you check the header the pump is connected to or move it to a new one and test?
