Query: It did not last long

I bought this burner two years ago for my office. I used it in average twice a (working) day to boil water for tea or make Italian coffee. So, not exactly an intense service. Yet, it just died last week, without apparent reason. The light turns on, but there is no heat. It was easy to clean, but its in-function light is too dim. You need to turn the ambient light off, in order to see it. This means it is easy to leave it on accidentally.
