E1 Is an RPM sensor error message. It simply means either the belt is not moving or the sensor is defective.
If the belt moves slowly then shuts down, check the RPM sensor located close to the drive pulley (under the motor hood). verify that it is as close to the pulley as possible without making contact. Verify that the magnet is present (mounted on the pulley). it will be a small round magnet, 3/8-1/2 inch diameter. If the magnet is missing, it may have attached itself somewhere on the treadmills frame. Reinstall it in the pulley.
Often there is an RPM LED located on the controller PCB. By manually passing the magnet past the sensor, you should see the LED flash. If so, that verifies the operation of the sensor, if not replace the sensor.
If the belt doesn't move at all, likely the motor controller PCB is defective..
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
