I have an E33 error code
Includes Keys, Ironman, Alliance, Milestone, Encore, HealthTrainer, some Smooth models, some CardioZone models, Galyans, and several other brands.
Meaning of code:
It means the walking belt is traveling faster than the set speed on the console.
First try calibrating the machine with the calibration help topic.
Adjust the "comp" adjustment pot on the controller and retry calibration.
Make sure the S F/B LED on the controller is flashing when the fan is moving inside the speed sensor. If not, check the speed sensor and the motor fan. Clean the sensor lens with a Q-tip and rubbing alcohol. If it still doesn't flash, check the motor fan "fins" and if they are OK, replace the speed sensor.
Check to see if the "fins" on the fan are broken are missing. A broken fan can cause a bad reading. If this is the case, replace the fan.
