Thermodynamics was never my favourite subject, but I suspect what happens is that the water boiling at the lower temperature created a higher pressure within the kettle (hence the screaming noise as pressure escapes the small nozzle), allowing the water to heat up to 100degC, and also the bimetallic strip.
