I just received my nano and thought it would be a doddle to use, it looks so simple. I filled a container with water to go over the minimum level, set the temperature to to to 45c, filled it with warm water which shows as being 40c. Press go and it just flashes up LO in red but does not start heating the water. What am I doing wrong ?
Also, not heating but getting colder. Just a beep when I switch it on then nothing.
