I am sad to report that last night Louise died! I knew it was bad news when she beeped in a longer way than she usually does. I had just tested my blood sugar less than five minutes earlier, and I was at 88, so I didn't think that was why she was beeping. The screen read "error code HWRFT," whatever that means. I quickly called Dexcom and got the bad news, she was dead, and has to be replaced. I had just put on a new sensor two days before, and I had been getting good readings up to that point, so it was completely out of the blue.
Has anyone else had to have their receiver replaced? I had been wearing her less than a year. I'm hoping that was just a fluke, that the next one will last longer.
