If you open the grill there is a top panel that slides out.. Remove it
You can then access the bracket that retains the hob-top to the body.. undo the screw on the bracket and the top can lift to change the ring as with the older model.
Here is a diagram for you

Hi Robert, I will go to the warehouse and look at that model.. I will contact you back later
If you remove the back panel there are a few screws going into the rear of the hob top that secure it to a bracket just under the control panel. You will need to undo the control panel to be able to do it.
