I serviced this Horizon GS1035T Treadmill in Harrison, Maine.
This is the third treadmill that I worked on this past year that was submerged in water due to a flooded basement. All three owners said that they had about 6 inches of water.
All three treadmills had slightly different levels of damage. The first one was a Reebok R8200 that had a damaged motor control board, drive motor, and rollers. We installed a new motor control board, a used motor found on eBay, saving a lot of money, and we left the rollers alone.
The second one was a ProForm 750CS that we ended up only replacing the rear roller due to rusted bearings.
This Horizon GS1035T had some bad sounding motor bearings, and the incline no longer worked.
If this ever happens to you, then I recommend these steps:
1.) unplug the treadmill and do not attempt to plug it in or operate it.
2.) Get the treadmill out of the water as soon as possible. Setting it up on four milk crates or something similar would do the trick, placing them under each of the four corners of the treadmill.
3.) If you can determine how deep the water was, and/or what got wet, that would be helpful to know what needs to be addressed.
4.) The motor cover needs to be removed, then the rollers and the belt and deck if those items got wet. Next remove the motor if there is a change that it was submerged.
5.) wipe down and dry all sides of the walk deck. These are typically made of MDF and will swell and be damaged with any prolonged contact with moisture.
6.) Turn the motor and rollers on each end in an attempt to get any water out of them that may have got into the bearings.
7.) The treadmill needs plenty of time to dry out. Initially a heat gun or hair dryer can help with this. Be careful about too much heat around circuit boards, wiring, and plastic, etc.. After the initial drying using this method, use a fan on the motor compartment for a few days until you are positive that all of the circuitry and wiring, and bearings, etc. are dried out.
