True Treadmill Errors and Service Messages

  • The True 600, 700, 725 and 750 series treadmills are equipped with built-in diagnostics and maintenance reminders that display either an error message or service message as they occur.
  •  The error messages that may be displayed by the built-in diagnostics are as follows:
    • E1:INCLINE
      • This means that the incline is moving when it has not been commanded to.
    • E1:MINIMUM
      • This is a minimum incline calibrating error that can be cleared by calibrating the incline.
    • E1:RANGE
      • This means the difference between the treadmills zero position and maximum incline is not sufficient.
    •  E1:STALL
      • This means that the incline is not moving when it has been commanded to.
    • E2:OVERSPEED
      • This occurs when acceleration greater than 2.1 mph occurs as this is greater acceleration than anticipated.
    • E2:CAL
      • This means feedback cannot reduce or increase speed to target and error can be cleared by calibrating treadmill.
    • E3:EEPROM
      • This error happens when a data error is detected on the EEprom.  The control panel needs replaced if this error occurs.
    • E5:SENSOR
      • This error occurs when there is no speed or RPM feedback detected from speed sensor.
  • The service messages that may be displayed by the built-in maintenance reminders are as follows:
    • S1:LUBE
      • This service message displays when it is time for inspection of the deck lubrication system.
    • S2:CLEAN
      • This service message displays every 500 miles and is your prompt to clean the treadmill.
    • S3:MOTOR
      • This service message displays every 2500 hours and is your prompt to check the motor brushes.
  • This information should help you understand the cause of the error message or code and how to take action to repair your True treadmill
