HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.
