Heating
The kettle starts off. Drag the dial past 55 % to start it, the way you would turn an old stovetop knob, or press START.

Holding the dial above 55 % for a moment starts it.
If the kettle is off, drag the DIAL slider above 55 %. The display reads HEATING and the light turns red.

See it in First cup, Keeping little hands off.
