Our white plastic one (JK62) did the same, blue light failed after a week or so. Three kettle replacements under warranty later and we're back to square one. The red boil light comes on which at least is acceptable. Shouldn't really expect too much,after all it's there to boil water and not to be a disco. At least we have clean water and electricity and shouldn't complain too much about a faulty coloured led in a kettle.
