I think it may be toast. Recently the reservoir ran dry, but the system shut the pump off as expected. I filled it back up, and checked to make sure the pump wasn't air locked, since that has happened before. When the system kicks on I can hear the motor in the pump running, but the impeller inside the pump doesn't move. And slowly the sound of the pump dies off a bit.
Any suggestions or does this need a new pump?
