Water boils at 100Â°C at standard pressure, no exceptions! However, the water temperature in the kettle is not even. Around the heating elements, the water rapidly reaches 100Â°C, even if the water in the rest of the kettle is cooler.
A pressure cooker would increase the boiling temperature and as such is no explanation for the '60C cooking kettle' of OP (lower atmospheric pressure would, but it's most likely the element around which water starts to cook quite quickly when overall all the water is not yet that hot).
