Question about Bowflex Treadclimber

Open Question

My Boflex treadclimber TC5000 makes a loud grinding sound when I turn it on. It is rubbing on the back edge. The tread belts are will still move and I don't have any error msgs. Any advice?

The last time I used the machine, I think I stepped off the back edge. It now seems to be touching/rubbing on the belt.

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.

Sounds like the hydraulic cylinders are bad. Try replacing them and should fix the problem.

You'll need inspect the movable areas of your unit by hand something may have come loose or see if their is any excessive lateral play could be worn or cracked bushings. Have some else help you by stepping off on either side to see where the sound more prominent. Unfortunately it a process of elimination good luck!

SOURCE: hey we moved my treadclimber tc5000 and now it

there could be several reasons why but i think that you have bumped a wire loose somewhere else. look and see on the control board that wires havent come loose. also check the wires from the console down to the control board. i have fixed several treadmils from people complaining about this same problem.

Why does my Bowflex TC5000 cut out?


If you're running the machine on a dedicated circuit then your unit is drawing too much current. This can be caused by friction and drag. Solution: Lube deck/belt. If problem persists, replace deck/belt. If you ignore this fix this will blow your controller. .

Makes a loud rubbing noise on one side


To be honest with you, these could be symptoms of a few different problems. Here are the most common ones and what it possibly sounds like:
1) It could be that the front roller has dislodged itself from the roller pulley. In other words, the motor keeps turning, and when you step on the walk belt, the pulley (the one with the small rubber belt) keeps turning, but the roller stops. This can cause grinding noises, and the pulley to "skid" the black belt, which can account for the black dust. You can usually tell this is the problem when it runs fine with nobody on it, but when you step on it, it grinds
2) It could also be that the walk belt is rubbing on the sides of the deck and/or side rails. This happens when the belt shifts over from the center. It would definitely sound like a grinding noise, and the black dust could be from the walk belt particles wearing down due to the rubbing.
3) It could also be the drive motor brushes. Let me explain. The motor has two small blocks on either side of it (inside the metal casing). Those two blocks actually carry electricity into the spinning part of the motor (called an armature). They actually make contact with the armature at all times while it spins. Those "small blocks" are made of a graphite (what pencil lead is made of). Well, with so much spinning, and so much contact from the armature, those things grind down with time. They sometimes grind down until they are stubs only. Then they start grinding. The powder in this case would be the brush graphite piling up (this would often be shiny dust, and is a dark grayish).
4) The grinding could also be roller bearings going bad.
**For #3, and 4 above, you have but to remove the small belt that attaches to the motor (rubber, black, and small attached to pulleys), and let the treadmill run for a few seconds by itself. You may get a "speed error code' after the treadmill does not detect speed, but at least you'll know if the grinding is coming from the motor. If it runs super quiet, even for a few seconds, then you know it may be #1, 2, or 4 above.
These are the most common issues based on your symptoms.

Treadles on tc5000 wobble and rub


You have to realign treadles ,take the back cover out and at the base of your unit you'll see two slides , couple of screws and yellow bushings if bushings are still in a good shape you can align treadles , if they're broken or worn out you have to replace them , I think there are 8 of them total ,they're called IGUS bushing
Good luck

Treadclimber tc5000 will switch on but start button won't work


Make sure the power cable is connected to a known good outlet (test outlet with a lamp or some other electronic device) and connected securely to the machine. Make sure the safety key is securely seated or belts will not move.

I am having trouble with my Bowflex TC5000. The calibrations is failing. The treads aren't moving but the monitor is trying to calibrate.


The motor must move the drive pulley for calibration to pass. remove rear covers and check drive belt. you should hear the lwr board relay click to engage the motor. if you hear it and the motor does not move and you have checked the belt then you need to test the motor. Typically remove the belt and turn by hand...it should be very smooth and spin freely. If not replace the motor. Direct 9 volts to the motor leads unplugged from the board will tell you if the motor is good. be careful as capacitors are present and risk of shock is always possible. capacitors stay charged for about 10 mins after unit is unplugged

Napa 8300 silicone is recommended. Apply under belts from front to back one fluid spray and also in bearing areas. Squeaking can also be caused by the center of the treadles rubbing to hard. If this is the case they need to be adjusted.

Hi ddmyatt.. They sell what is call dry lube at sports store's. for spraying under the tread's and on the wheels that the tread run's on.. Lift the tread and spray as far under it as you can on both side's. She'll be lot's quieter then before and lots easier on the motor too..
