Russell Hobbs Glass Kettle (Olton B92)

I am offering my old Russell Hobbs glass kettle. The kettle illuminates with a blue light while it is boiling water. The kettle automatically switches off when the water boils, allowing the kettle to be lifted off the base to pour the water. However, there is one small fault. If the kettle is lifted from the base before the water has boiled, the switch is supposed to automatically return to the "Off" position. On this kettle it doesn't, you have to remember to flick the switch up. It works perfectly if the kettle is left on the base until the water has boiled.
