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.

Error Messages

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 treadmill's zero position and the 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 the treadmill.
E3:EEPROM
This error happens when a data error is detected on the EEprom.  The control panel needs to be replaced if this error occurs.
E5:SENSOR
This error occurs when there is no speed or RPM feedback detected from the speed sensor.

Service Messages

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.
