To disassemble the Russell Hobbs 15081steam glide iron, you have to remove the two hidden screws on the handle. To locate the first screw remove the two adjacent blue buttons which are each held in with two hidden clips front and rear, so lever out with small screwdriver or similar. The second hidden screw is under the pivots of the water inlet lid.(I broke one of the plastic pivots but no big deal). Then using a thin blade, separate the top half of the handle from the bottom half of the handle. A bit of force is needed as there are more plastic clips. I started from the rear.
Once the top half the handle is removed, other screws become visible, so teardown is not hard, just note which screws go where, as they are different lengths.
My problem was that some of the screws/bolts were so corroded I needed to drill them out. The thermostat was also corroded, which probably explained why the thermal fuse had blown. The element was fine.
