Images show the waffle maker with lid closed, with lid opened (waffle plates removed) and one of the two identical waffle plates. Waffle plates are removed (normally for cleaning) by pressing the grey buttons on the side.

To extract the bottom heating element, first undo the 5 black screws in the handle to remove some of the black plastic plastic surround. (Note 2 of the screws are shorter, see green arrows).

Undo the 4 corner screws in the metal inner casing (eg red arrow)

Undo 2 screws and brackets holding the heating element to the inner casings eg blue arrow. Now, by pressing in the grey button on the side, you can wiggle the inner casing with the heating element from the outer casing. Care not to lose the sprung loaded grey button and sprung loaded thermostat assembly in the middle.
