Some owners of the Peloton tread have run into an issue where after pressing the wake button, rather than turn on as normal, the wake button will instead flash red several times.
The first thing to try is to detach and re-attach the magnetic safety sensor. This can sometimes come loose and cause the Tread to get confused. This isn’t the most common solution, but it’s the easiest to try, so try that first!
If you are still having problems, the next solution to fix this is by doing a complete power down of the Tread. First, find the power button on the bottom right of the Tread base. Turn this switch to off. Unplug the Tread’s power from the wall. Wait somewhere from 5-10 seconds until you hear a “click” sound. Plug the power back in and swap the power switch back to “On”. Wake your Tread back up.
In most cases, this will fix the issue of your Peloton Tread having blinking red lights, and not turning on. An alternative solution, if this still does not fix it or it continues to happen, would be to do a factory reset (you don’t lose any data, but might have to log back in and re-adjust settings).
