E1

An E1 error code is a very broad code. It is important to know when the E1 occurs and what was being done when it occurred. 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. The motor control board will shut down due to the motor pulling too much current, triggering a safety shut down. It is important to maintain a proper lubrication schedule for your treadmill. The lubrication frequency will vary depending on the model, please refer to the lubrication instructions in the owner's manual. When lubricating be sure to use a 100% silicone non-aerosol treadmill lubricant, applying 1-oz.

After lubricating the running belt, if you still continue to have problems or it returns after just a few weeks, the running belt may have become glazed. This is a term used that describes the pores on the underside of the running belt closing due to excess friction. When this occurs, the running belt can no longer absorb lubrication. In this instance you may need to replace the running belt as continued use can lead to damage of other components such as the motor and the motor control board.

If the running belt stops after 6 seconds of starting the treadmill, this may indicate that either the speed sensor needs adjusting/replacing or the main wire harness is damaged.

If there is no belt movement, or you notice a burning smell coming from the motor area, this may be an indication that the motor or motor control board has become damaged. Without lubrication, continued use can cause damage to the motor and/or the motor control board which may require replacing of these components. If needing to replace either of these components, it will likely be necessary to replace the running belt as well. Doing so will prevent friction from damaging the newly installed components or other components in the machine.

E6 or E7

An E6 or E7 error code is an incline error code. The E7 code means the potentiometer value the console is reading from the lift motor is out of range. This can happen when there is a bad wire harness connection or a damaged wire harness. It could also just mean the incline motor needs to be adjusted back into range. If all wire connections look ok, the incline motor will need to be adjusted.

  1. Turn the power OFF, wait 5-seconds and turn back ON.
  2. Get into test mode and enter through the I/O testing step. This screen will display the potentiometer value of the incline motor. Different models will have different values. Check to see if the running deck is raised to high incline level or if it is at the low level. If the running deck is at a low position press the incline up button. This will cause the incline motor to raise the running deck up. When the deck gets to a mid-level position, press the incline up button a second time to stop the deck. If the running deck is in a high incline position, use the incline down button to adjust the deck to a mid-level position.
  3. Once the unit is in the mid-level position, power the treadmill off for 5-seconds and then power it back ON.
  4. Start the treadmill.
  5. Once the treadmill starts the running deck will move to the level 0 position. If this does not resolve the issue or it will not adjust please contact customer service.

Also note that not all models will have the ability to adjust the incline motor. If the adjustment procedure is not found in the Owner’s Manual then contact customer service.
