SOURCE: I have a Nautilus Bowflex 5 series treadmill.

I will have to check the error code but sounds like a heat problem. When you get too much friction between the walk belt and the deck it builds a lot of heat which creates more drag on the motor. This causes the motor to overheat which in turn usually shuts the machine off. You can let it cool and go back exercising until the cycle repeats. If this sounds like your issue, try lubricating the walking belt. If it's not in bad shape it should make a difference. The machine should run longer. 10-15 is pretty quick though so it make take a couple of application of lubricant. The belt may need replacing if the need for lubricant becomes too regular.

SOURCE: Our Nautilus T514 treadmill stops


Try clearing the error by unplugging the treadmil. if it doesn't clear then try and press stop button for 10 seconds. Insure cable is connected securely to Console. All wires in cable should be intact. If any are cut or crimped, replace cable. If error doesn't go then lubricate the treadmill as given in this manual---

PLO5 error message on Quinton Clubtrack treadmill

Try to clear the error message. God bless you

1 )Locate the reset switch on the underside of the treadmill console. Usually the button is large enough to trigger with a pencil eraser or Q-tip. Plug the treadmill plug back into the wall. Use the Q-tip to press the reset button. It may be necessary to hold the reset button down for a few seconds. "CL11" will appear in the display of the treadmill.

  • 2

Press the reset button one more time with the Q-tip. "CL21" should appear on the screen. Press the enter key. The display will change again and show "CL22." Keep pressing the enter key until the numbers cycle through to the number "CL26." Press enter one more time. The letter E should appear on the display screen.

  • 3

Press enter twice more. The letters "SS" should appear on the screen. When this happens, press the start/stop key. Making sure to keep well away from the tread, press enter to start the treadmill. The treadmill will start on its own. The treadmill will stop on its own after a few seconds. When it stops, press the power key two times. Remove the safety key and put in a safe place. Your treadmill is reset

T518 keeps shutting off

Did anyone address the issue of lubrication for the unit since the increase of friction will overheat components thus causing the unit to shut down.
