Mine failed last week for the third time. This time they replaced the entire head assembly that contains the Hi-limit switches. The explanation was that sometimes the head assembly develops small leaks that cause the switches to fail.
Sounds more like a design flaw to me, which could continue to cause problems after the warranty expires.
