Query: Stopped working?

We were very happy with this product initially (it made awesome hard-boiled eggs), but after a while eggs started exploding. I am talking about a real explosion with the microwave door blasting open and egg splattered all over the kitchen -- my spouse is incidentally cleaning up the latest (and last) of such incident.Given the simplicity of the contraption, how can this happen? Premature plastic aging?
