I have a photo of the actual wiring for this area of one White Knight machine. [The live feed comes back from the front panel time selector dial, thru the dark brown cable with the white bands on it, goes down one grey wire to the thermostat embedded in the back panel, comes back up on the other grey cable to power the first heater element, where the red wire is also connected to supply a live feed to the selector switch of the high temp setting, which returns on the black wire to supply the second heating element - and the other end of both elements then go down the blue wire to the trip/reset switch [red button on back panel] and then exit thru the neutral mains wire.
For a single-element configuration, presumably the red and the black wires would not exist.
By the way, there is a second thermostat located in the exhaust pipe manifold. Either of the two thermostats may close down the heater(s) when needed.
You can see the connections for the two heating elements, the inlet thermostat, the reset trip and the mains cable electricity wiring block [all adjacent to each other near the top corner of the back panel] for a White Knight Sensordry Dual Heat Tumble Dryer model CL437WV at http://home.btconnect.com/gc/tumbledryer.jpg
