Aria shows a "Step Off - Sensing error" message

[Andrew103]

My Aria 2 has been doing some unusual things. I've had a look at some of the other threads but not sure they exactly match my situation.

The scale has been in the same place on a hard wood floor for about three years, and last had the batteries changed about four months ago. Since that time it has been working normally.

Suddenly, about a month ago, one morning the scale didn't recognise my wife any more - my name/details were still there but she showed up as "GUEST". 

About a week after that, I started getting what other people have described as the "Step Off - Sensing" error. Here's what happens:

• I walk into the room and can see the scale is "off" - there is nothing on the display.
• When I get about one metre away (before I even step on) it the display shows "STEP" then changes to "SENS".
• It then repeats this pattern over and over "STEP" > "SENS" > "STEP" > "SENS" > "STEP" > "SENS" ...  It doesn't even scroll to display the full message text - it looks like it wants to scroll, but the display changes after to the next word too quickly.
• This goes on for quite some time - long enough that I haven't seen it stop yet. But eventually I'll leave the room and if I come back later in the day the display will be blank, then it starts up again as I walk across the room.
• If I actually step on the scale, I get the full "STEP OFF" message, then it says "THINKING" for a couple of seconds, then goes back to the same "STEP" > "SENS" loop.   

After this had been happening for about a week, the batteries ran out. I replaced them, went through the full setup process, and afterwards, the same thing happens.

Totally understand!! Same thing is happening to me and no one can figure it out!! Really sucks - machine worked for a couple of years. I asked Fitbit to replace and they won't. I hope someone figures this out!!
