Fitness world treadmill wont start it showing on screen error code 7 pls help

If the console lights up, but the treadmill won't start, the motor controller could be damaged. Loose wires under the motor hood or in the console can cause your treadmill not to start. Remove the screws and lift off the motor hood. Look around for any obvious damage, burns, loose or broken wires. The problem does not seem related to a blown fuse. But check your warranty first before opening something.

see the comentary 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.
Run the software calibration for easy diagnostic and fix it. God bless you

My motorized Treadmill is showing error E09 how can l clear the error?

pls do re-calibration

This error shows up if motor controller detects a failed part. This isn’t a reset-able error. Treadmill will not allow workouts until serviced.
Solution
Main motor wires/leads could be disconnected at the start of a workout. If the motor is properly connected and in working condition then the drive transistor could have failed. Check Motor Controller.

Error 7 is a Safety Key Error..
that's the red magnetic circular thingy on the console.
Simply secure the safety key in place and try it again
