Some electric kettles have a digital thermostat on them that can allow for precise setting of the temperature of the water anywhere up to 100 °C (212 °F).
If, for some reason, your electric kettle gets dirty, rinse with water and light soap, fill and boil, then discard the water. Do not put your electric kettle in the dishwasher as you will risk damaging it. The electrical contacts of the kettle should never be submerged in water. Doing so can potentially create a short circuit and/or permanently damage the kettle. Be wary of mineral buildups that can reduce the quality of the water over time. If the inside looks dirty, give it a good rinse, boil, and discard.
You can also use your coffee maker as a hot water dispenser by not putting a coffee pod inside the brewing chamber.
