ECG Fix!

Along with a lot of others here, my Apple Watch 7 ECG app stopped working. I spent an hour on the phone with an Apple service guy unpairing/re-pairing etc. and eventually he got me to send it to Apple. They sent a replacement watch 7 (different s/n) and, after restoring from my backup (which involved updating the OS to 9.5.1) it behaved the same, i.e. ECG didn't work.


That's what brought me here, where I found one thread that suggested disabling: Settings>Accessibility>Assistive Touch. I checked and mine was already disabled, but figuring I had nothing to lose, I enabled it and reset the watch and ... it worked! My ECG app is again functioning. I have since disabled Assistive Touch and everything still works.


I'm not sure what, exactly, fixed the ECG because I enabled Assistive Touch in Settings on both the watch and the iPhone and I forced-reset the watch. It may be sufficient just to toggle the Assistive Touch setting on the watch. It may or may not need the iPhone to be involved and you may or may not need to restart or reset the watch, but I'm certain the problem is somehow connected to the Assistive Touch setting.


Good luck!

Apple Watch Series 7, watchOS 9

Toggling assistive touch worked for me! Oddly enough my ecg was working if I took the band off and just pressed it onto my wrist, but not with the band. Toggling this made it work with the band on.

I have a series 6. I’ve tried everything since I got the watch to get ecg to work. Just tired this solution didn’t do anything. The odd time I get it to work I have to firmly press the crown in the message then comes telling you ‘no need to press’, I keep pressing the crown then firmly press down on watch on my wrist then 1 in 10 attempts it will work. Then it won’t work again for months.

It's possible you have a hardware problem. Apple Support was very helpful. I was on the phone—at their expense— for over an hour before the support person decided he couldn't fix it and emailed me a mailing label to send my watch to Apple. They sent me a new watch but, after restoring it to the same state as the previous one, it had exactly the same problem, which is when I *knew* it was software and eventually landed on the fix above.


Give them a call or chat via this site or via the Apple Support app.

I also have a series 6 and I’m seeing virtually the same thing as Goomanguy. I “think” this behavior started about May or June of 2024. Not sure if this was after an update as I don’t use ECG every week. But it seems to have started after the 10.5 update. No luck with multiple resets or playing with assistive touch. Regretting I didn’t grab a new series 9 for over $100 off on prime day. :-(

This didn’t work for me on Apple Watch 8 (watch is up-to-date on updates). Assistive Touch (AT) was off, so I toggled it on and back off again, restarted the watch, but ECG still doesn’t recognize my finger. I don’t want to reset my watch. Is there any other way to fix this? I really would like my watch to provide full functionality, but ECG is more important than Assistive Touch. AT is off on my watch, but ECG still doesn’t work. What does Apple have for a suggestion?
