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

Errors for True Treadmills E5 Sensor E2 Cal S1 Lube and more

E1 usually suggests it is and Electrical error and would probably require someone with knowledge of treadmills to rectify the error.
It is very unlikely the ordinary Jo Blo can fix this problem.

I had the same thing on my ps300 today. I just posted the solution on another fixya post regarding the true ps100. Essentially, clean the sensor and magnet on the motors driven pulley and move the sensor as close to the magnet without it touching the magnet. It worked for me.

Buckmanservices.com solved the E1 code issue only $30 fixed it from online told me what to do

E1 error code : Unplug unit remove motor shroud and check the distance between the speed sensor and the flywheel and ensure that the speed sensor is properly attached to the motor frame. Check also speed sensor connections.
Unplug the electrical cord from the wall outlet and from the treadmill, wait 1 minute and turn the power switch on again. If treadmill recovers to normal operation, you may continue to use the treadmill.
Check the motor brushes either they worn or not sitting properly

Your problem might be that a magnet has fallen off within the treadmill. Here's an illustrated guide that should make fixing it easy: http://fixmytreadmill.blogspot.com/2010/10/how-to-fix-treadmill-e1-error.html

Good luck.

Yes you may be able to recalabrate the machine. A grade stall is when the machine does bot think the machine is at the right height. A bad lower board can also be the problem. True has those treadmills brought overseas. There not the american made quality of the units they useto make in MO.

It can be fixed. I know all the employees at True
