Error E2 on a Weslo WLTL97540 treadmill usually means that there is a problem with the incline motor. To resolve the issue, try the following steps:

1. Unplug the treadmill from the electrical outlet.
2. Locate the incline motor and check for any visible damage or debris.
3. Clean the incline motor and surrounding area.
4. Reconnect the power and attempt to raise the incline.
5. If the error persists, you may need to replace the incline motor.

If you are not comfortable performing these steps or if the error persists after trying these steps, consider contacting a professional repair service.

Error code E2 on a treadmill typically indicates a problem with the speed sensor. The speed sensor is a small device that measures the speed of the treadmill belt and sends a signal to the treadmill's control panel. If the sensor is not functioning properly, it can cause the treadmill to display an E2 error and prevent the belt from moving.
There are a few potential causes of an E2 error on a treadmill:

1. The speed sensor may be loose or misaligned. Make sure that the sensor is securely attached to the treadmill frame and properly aligned with the magnet on the flywheel.
2. The speed sensor wire may be damaged. Check the wire for any visible damage, such as fraying or cuts.
3. The control panel may be malfunctioning. If the error persists even after checking the sensor and wire, the control panel itself may be the issue. In this case, it may be necessary to have the treadmill serviced by a professional.

I hope this information is helpful. If you continue to experience problems with your treadmill, it is recommended to have it serviced by a professional to ensure that it is functioning safely and correctly.

Why don't you try to get support from the manufacturer's website? They will be able to interpret the error code which will point you at the problem.

  • 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.

does the incline work at all. if not try to calibrate the incline. if this fails something could be wrong with the incline motor

To fix the error you have to put the safety key in start it it and wait for it to say E7. Now press stop and incline( up) together and hold for 20 seconds. Your treadmill will start to incline up. Take out your safety key. You just restarted your treadmill and can now put the safety key back and your problem will be fixed.

You may have a beltand deck problem. Test by the following procedure:
without the poweron stand on the walking belt, push the belt in the, direction it normally turns. If the belt is very difficult to turn (on most treadmill this means that you have high belt/deck friction I first apply silicone lubricant between the belt & deck to see if that clears up the problem. Most problems originate from the belt and deck 75 to 85% of the time

Because you are hearing the lift motor making a noise, it sounds like the gears in the motor are bad. The fix is to replace the lift motor.
