SOURCE: the machine will quit wright after you start and

Had my TC5000 for a year and this is the first time this happened. I use it everyday. Googled "Bowflex Teadclimber error codes" and found this link  download.dfxi.com/supportdocs/AM/Bowflex/BFX_TC135_AM_2008.pdf which is a pdf manual. 
I'm going to try this fix now, hope it works for you and me
Here's what it says for ERR LS:
Belts stop turning and “err LS” or “err OS” is displayed Calibration Re-calibrate machine using Owner’s Manual calibration procedure. Speed sensor 1. Cycle power off and on. 2. Put the machine in calibration mode (see Calibration procedure in Owner’s Manual) but do not start the calibration routine. 3. Remove right rear plastic cover to view LED diagnostics on control board. Caution: Machine is on. Current is active!! 4. Locate LED D on the motor controller board. LED may be lit or unlit. 5. Manually advance the treadle with your foot, and check if LED D is blinking. 6. If LED D is not blinking, then the speed sensor is not supplying a signal. Check that the speed sensor wire is plugged into the motor controller board, to the connection labeled “P1”. Check connection of speed sensor to jumper wire. Check speed sensor adjustment (use business card to set gap between sensor and pulley). If LED D still does not flash replace sensor. I/O cables If LED D is flashing when the belts are turning but err LS or OS persists check connections and for signs of visible damage to any of the three I/O cables. If no damage, check continuity using a multi-meter. If a multi-meter is not available contact customer service for replacement cables and further assistance.

SOURCE: Bowflex TC5000 L5 Belt will not move antmore.

Dear Sir:

Hello , I hope everything is fine with your family.

Thank you by your request, and I will help you inmediately.

You have a Mechanical problem, please do the following:


Please do this with carefully!

The motor drive belt is adjusted independently from the walking belt. Some newer models have an auto tensioner which is a lever that has a wheel that puts pressure on the drive belt and a spring on the other end that automatically loads the belt to the proper tension. You should not adjust these since they are preset.

Tension can be affected slightly by adjusting the tension of the walking belt but if you have a slipping problem, the drive belt will require replacement. If your drive belt is too loose, it will slip on the front roller pulley or the motor pulley. If it is too tight, it will increase your amp draw to the point that you may have an electronics or motor problem. Due to this, it is better to be on the safe side and replace a drive belt rather than risk over tightening it. A drive belt is usually $29.99 or less while many parts you can damage by over tightening can be more than $300.

Additionally, too much tension can cause bearing failure in the motor and the front roller and front roller pulley failure. It is better to having the belt a little too tight rather than too loose due to the possibility of injury if the belt slips.

Motor Belt Adjustment- Icon Units

DO NOT REMOVE ANY OF THE MOUNTING BOLTS TO THE MOTOR. SOME MODELS WILL REQUIRE 2 9/16" WRENCHES AND MAY REQUIRE TWO PEOPLE TO ACCOMPLISH THE REPAIRS

Before beginning this repair: Check to make certain that the drive belt requires adjustment. Check out belt slipping instructions or with the motor cover removed, walk on the belt normally and try to stallthe belt to make it slip.
Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley.

Step 1- Find the motor mounts
. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability. Some models have a single jack bolt and others have an auto tensioner. Single jack bolts are the easiest to adjust.

Step 2- Find the set bolt(s) on the motor. This is typically run through only one side of the motor mount or may be on both sides but it does not run the full length of the mounting. Loosen this bolt(s) but do not remove. Jack bolt models will have flat mounts and may contain up to four bolts.

Step 3- Look for a bolt that will tension the motor. If it has this bolt, it typically runs in the same direction parallel with the drive and walking belts. If your treadmill is not equipped with this bolt, skip to Step 4. If your treadmill is equipped with this bolt (very few are) the repair will only require one person. Using 2 7/16" wrenches, make a few turns to this bolt, tighten the bolts from Steps 1 and 2 and test your treadmill for slipping. If belt continues to slip, repeat Steps 1, 2, & 3. If a second attempt does not repair the problem, skip to Step 5.

Step 4-
If your treadmill is not equipped with a bolt as described in Step 3, the drive belt must be tensioned by hand. While one person applied increased tension to the drive belt, the other person should tighten the motor set bolt(s) that are described in Step 2. Tighten the bolt from Step 1 and test. If the problem is not corrected, repeat Steps 1, 2, & 4 and retest. If problem persists, skip to Step 5.

Step 5-
If you have arrived at this step, let's make sure you have a drive belt tension problem. With the motor cover removed, walk on the belt normally and try to stall the belt to make it slip. Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley. If this is the problem, you will notice it because the plastic will usually make a loud squealing sound on the metal front roller. The entire front roller assembly repaired or replaced (see the help topic on replacing a pulley) and the drive belt must be replaced. We suggest replacing the drive belt as well because it is a low cost item and will most likely, have suffered unusual wear from the problem. Another possibility is that the drive belt has worn down. In some cases, belt dressing may help correct the problem. If not, the drive belt must be replaced.

Step 6- The belt should be able to be turned by hand at approximately a 90 degree angle from its normal operating position.


Thank you in advance, sincerely. God bless you.

TREADCLIMBER tc5000 error code L5


Step 1:

see the comment. and fix it. Run the software calibration.
"SAFETY SHUTDOWN Loss of Speed Signal" or "L5" WITH NO belt movement
The speed sensor is not recognizing any motor movement. This displays the error message to the upper board. Refer to the proper flowchart.

Step 2:

The Steps for Newer Style Console Calibration:

  1. 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.)

  2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).

  3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.

  4. 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.

  5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.

  6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.

  7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.

  8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.

  9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."

  10. Press ENTER. You should see "SS" or "55" in the console.

  11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.

  12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.

  13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.

  14. 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.

  15. If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in). Troubleshooting the failure would be the next step.

Who can repair my bowflex treadmill 5 series in toronto


There are four typical causes for this problem :

1) The walking belt and/or deck are worn. (85% of the time)
2) The walking belt and/or motor belt are too tight- if you have adjusted either recently. (8% of the time)
3) The motor has lost torque and needs brushes or has demagnetized. (5% of the time)
4) The controller board is dropping output. (2% of the time) . You can do it foryourlsef. However i will give some websites FOR TO CONTACT THEM:

My Bowflex Treadclimber keeps coming up with an Error L5. This error message shows up 5 seconds after turning the machine on. My husband looked it up yesterday and said that the machine needs to be...


L5 due to the screen is actually LS (lost signal) the first place to check is the gap of the speed sensor. under left treadle 2 black wires. Removing the rear covers will allow you to see the lwr cntrl board and move the belt by hand. The gren led light should flash once per revolution of the drive pulley. If not then it is the speed sensor. Adjust sensor to pully about thickness of a credit card. then calibrate unit.
LS is also tripped by any broken wires or bad connections. Start at sensor and board first.
