Hi,
I am sorry for the delayed response as i was not at my desk.
This is a common problem on these treadmills.You will need to check the speed sensor for proper alignment and
function. it should be located near the front roller or mounted on the
motor. It should be within a credit cards width of the magnet or toothed
wheel. If properly adjusted check with an ammeter to see if it is
opening and closing by manually spinning the front roller or motor
flywheel. If it isn't replace the sensor. If it is functioning make sure
you are getting 5vdc to it across the wires. If you are not replace the
upper control board(console). If you are getting the proper voltage
then replace the lower control board(motor controller).
Let me know,once done so that we could proceed further.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
any chance of a diagram???
Thanks for your response!!
I apologize as i was in my home town. I came back yesterday. I have to check the same. If you could provide me with the complete model number, i could try to pull it out from my database or would guide you where you could get this diagram or service manual.
Thanks and Regards

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 speed sensor, test for open or faulty. tight the connector very well. RUN the software calibration for easy troubleshooting and fix it.
see the diagram attached. and follow steps.
God bless you

The
Steps for Newer Style Console Calibration
Locate the calibration area on the
rear or underside of the console (a hole, near the console's center,
that goes through to the electronics board. (This hole should not
have a screw in it.)
Insert a pencil (eraser end),
into the hole and feel around for the cal button (will click
when pressed).
Press the button 2 times
(with the pencil eraser). The first click should show CL11
in the console, the second click should show CL21.
If the process was done correctly,
and CL21 appears in the console, you are in "calibration
mode." The next few steps consists of pressing buttons
on the console and observing settings. This will not require
any other tools.
Press ENTER. CL22 should display
in the TIME window and (??) in the SPEED window.
Press ENTER. CL23 should display
in the TIME window and (??) in the SPEED window.
Press ENTER. CL24 should display
in the TIME window and (??) in the SPEED window.
Press ENTER. CL25 should
display in the TIME window and (??) in the SPEED window.
Press ENTER. CL26 should
display in the TIME window. You should then see the
letter "E."
Press ENTER. You should see "SS"
or "55" in the console.
Push the STOP/START button. For
safety, at this point, you should step off, or be off, the
treadmill.
Push the ENTER button. The walking
belt should start to move, accelerate to maximum speed, then stop on
its own.
When the belt stops, the
incline should self test by raising to its highest
incline position, then lowering back down to its lowest
position.
Once the incline test is complete,
push the POWER button 2 times. The unit should shut off and the
console should go completely blank. If this happens, the
treadmill is done calibrating and is ready for use.
