It run just in one speed and error message E1 on screen it.s a darby Silhouette DDR583R

Ask the manufacturer

An E1 code just means that the console is not getting a reading from the reed switch (Speed Sensor). If the running belt moves for several minutes and then produces the E1 error, this is most commonly a result of the running belt needing lubrication. ... When this occurs, the running belt can no longer absorb lubrication.

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

Step 1:

ERR 1 - Motor Movement

ERR1 indicates a speed issue. In this case, the motor speed as reported from the optic sensor differs

from the speed setting.

Analysis: Optic sensor signal issue -- Either the optic sensor signal is not right, or it is read incorrectly, or

the signal is not reaching the display.

Clean the s.speed , test for open or faulty-see the diagram for adjust. tight the connector very well.

God bless you

Step 2:

Dear Sir:
This is probably a 1) faulty speed sensor or 2)the speed sensor is not plugged in properly. Its also possibly a 3) faulty motor control board or lower board 4) Main motor faulty. . The error codes will differ between makes and models but could be e1.You must test

see my personal TIPS for diagnose and troubleshooting.

See if you can run the software calibration for diagnose and trouble.

sincerely. God bless you.

E1 is a speed error. Try adjusting the speed sensor to approx. 1/8" from the front roller magnet and make sure the sensor does not hit the front roller. It will break it off.

Good luck.

Change the transmission speed sensor
