Erg mode not working in workout mode

I’ve tried all of the fixes in this message chain. My kickr firmware is up to date. I’ve uninstalled and reinstalled the Zwift apps on my phone and TV. I was able to do one workout last week ERG mode. Every other time I have tried, including wasting 30 minutes this morning, I am unable to get ERG mode to work. The lack of attention to this issue by ZWIFT doesn’t make sense. I’m considering dropping my Zwift subscritption.

I am dropping mine. I’ve had enough. For 17.99 a month you should minimally get a response on a support issue within 48hrs. Here you get precisely ■■■■. Not worth it. Switching to trainer road.

Hi @Marko_Buric

What issue are you trying to solve. What trainer and computer do you use. How do you connect to the trainer.

Did you try rolling back the firmware to an earlier version? I assume you are using an Apple TV or iPhone, this seems to be an issue with Mac devices. Rolling back the firmware on the Kickr has solved the issue for others.

ERG mode doesn’t work in workout mode. I use a kickr 2020 (updated firmware), Iphone app and Apple TV. I have deleted and reinstalled the iphone companion and apple tv apps. ERG mode will sometimes work when I do an inidividual workout for this setup, but not always. For the last two months I have not been able to get it to work when doing a group workout. It does seem to work if I use my Ipad instead of the iphone/apple TV setup.

Thanks for your reply. Yes, I am using the apple TV/Ipone setup. No, I have not tried that. I’ll try it now. I assume that rolling back the firmware is straightforward.

the one that is in this forum that i posted about where ERG mode either does not work (either does not start, or shuts off and won’t restart, or erratically jumps the wattage all over so it doesn’t hold the power). Suito. Ipad mini latest ios.

Try rolling back the firmware on your kickr, see this thread:

How to downgrade the firmware:

It is a hidden process… load up the wahoo app, connect to the trainer, then “click/touch” the trainer icon 10 or 15 times to get the hidden menu to pop up. You can roll back firmware or do a factory spindown.

If I recall correctly, going back two versions should solve it.

Wow. I never would have come up with that. I’m able to get to the hidden menu. It appears the app has been updated. The first time I tried this I only gotthe option to Spindown, Forget Sensor or Help. However, I closed the app and tried it again and this time it opened it gave me the firmware option. I’m reverting to 3.4.71.

you can also use the Wahoo Utility app, looks like this:

Getting the same issue where erg signal not being sent to trainer and kickr snap stuck at same resistance during free ride and rest periods. Disaster.

Hi @Mark_Dobbin_Ards_CC

I moved your post here, scroll up and see if that help.

Mike, thanks so much for your help. Everything is working again!

Hi! I’m using an Elite Direto XR on a PC via ANT+.
Sometimes the ERG is gone/not showing on the Companion app. Re-pairing solves it so not the biggest deal.
The strangest thing is if I pause on an ascent for refilling water etc, the trainer stops using the incline and it’s like riding a flat route.

I don’t want to try fiddling with the pairing in mid ride afraid of losing the ride. Any suggestions to solve this problem?

Replying to myself, today I lost the incline on Sand and Sequoias. No feel of any gradient at all.
The only quick fix was to jump off, disconnect the trainer, unpair all, reconnect cable and search/pair the trainer again.

This thing annoys me very much as it prevents me from joining any event or group ride.

Windows 10 ant+ taxc flux connected fec .Workout mode first time today impossible to hold watts totally erratic as if pedalling in squares any solutions

Same problem. Some details:

  • bug occurs just on Windows, not on iOS
  • bug occurs regardless if trainer is connected via BT or ANT+
  • used trainer: Wahoo Kickr Core (2019)

Folks, I’m having what I htink is the same problem but I’m very unsure. Running Zwift on Apple TV with a Tacx Vortex plus garmin sensors, connecting via the Companion app to the Vortex except for the HRM and cadence sensor which seems not to work if I connect via the Vortex.

Anyway, updated my firmware after failing to enter ERG mode at all for a few weeks. That seemed to fix things, but today tried the Faster Hills workout. First two reps were sort-of ok but the wattage wasnt’ coming up to target - at last 15-20W short. At the thrid rep everything went haywire – suddenly spinning in top gear, then the brake kicks in hard and I’m going from pushing 120W to 4-500 in a matter of seconds. Abandonned the workout and did a “just ride” and everything worked fine - proper sensitivity to gradient changes albeit a bit laggy.

Too many devices in the chain? Some other cause? Any suggestions? Had relatively few problems with the old Mac +ANT dongle set-up, despite issues streaming to the TV, but I’ve found the Apple TV option a constant pain.

Yesterday for the first time in one year of zwifting mit ERG was messing up, too. Workout was ramping up the resistance as usual, but when it should drop from 295W → 135W I noticed that the power did not adjust, after a minute it should have gone up to 250W, but suddenly I had massive resistance and ended up at 400W to keep 70 rpm…
Exited Zwift, restartet the trainer, restarted the workout and every went good. But this has never happened before in nearly 100 workouts.

Windows 11, BT5.0 Dongle and Elite Direto XR trainer (latest firmware, haver hab to update it) + Polar H10 heart-rate monitor.

Maybe Windows 11 rolled out some new drivers for the Realtek BT chipset, but since this happened mit-workout I dont think so.
