First port of call is a new genuine blue dalek (pressure cap). If that doesn`t fix it, then you`ll be looking at head or/and gasket problem 
Mine did exactly what you`ve described, pressurised the system and held pressure indefinitely, so it never allowed the coolant from the expansion tank to return when the engine cooled down. Cylinder head was severely cracked (scrap), yet the engine worked fine

Keep it real.
