Check the water control valve on the bulkhead in the engine bay. You will see it almost inline with the engine, with a pipe going in the bottom and out the side. There is a cable clipped to it. If the cable is not clipped on, or is incorrectly aligned, you will get no hot water through the matrix. You can test by unclipping the operating cable and moving the armature by hand to see if the porblem rectifies itself. Also check that the cable moves when you adjust the temp on the control unit.

If it has just been changed, then it is more than likely that the cable has not been clipped on and adjusted correctly.
