Mend Heatslave 20/25 Water Stopped System

Expansion vessel full of hot water?

I have a Heatslave 20/25 and it stopped pumping water around the system. I thought it was the pump, but the expansion vessel is full of very hot water and may be the problem.
Can you advise me?

The full expansion vessel can't be the cause, but it IS a symptom of another problem.
There is something blocking the water flow after the expansion vessel, the water level within will obviously go up as it have nowhere else to go.

Turn the furnace OFF. Turn the pump off if it don't turn itself off. As the water cool down and contract, the water level will go back down.
Call a plumber to check the pipes now.
