This answer is a little lateral to the question but I hope it's of some value to you. Let the kettle die it's natural death.
Kettles burn up huge amounts of energy to heat a couple of cups of water. In fact, it's so much energy, that in the UK the power grid has to spin up extra turbines in time with the ad breaks on Eastenders at certain times of the day. Those times being morning and afternoon tea.
Consider instead heating your tea / coffee in the microwave. If you already have one and only use it for heating up leftovers this would count towards "multiple uses" for a device. They are very power efficient, though a little slower at heating a single cup of coffee.
Seriously Rick? Seriously? You might as well just read this tiny ad:
