What to do if the scrub vacuum fan won't turn on in my Tennant Floor Machine?
- D
  dodsonjesseSep 12, 2025
  If the scrub vacuum fan on your Tennant Floor Machine won't turn on, start by checking if the vacuum fan/squeegee button is activated. If the recovery tank is full, drain it. Foam buildup in the recovery tank can also cause this issue, so empty the tank. You might need to use less detergent or a defoamer to prevent foam. Lastly, inspect the recovery tank sensor for dirt or being stuck; clean or replace it as needed.

How to fix trailing water or poor water pickup with my Tennant Scrubber?
- A
  Ashley RoblesAug 25, 2025
  If your Tennant Scrubber leaves water behind or isn't picking it up well, several factors could be the cause. First, ensure the vacuum fan is turned on. Check the squeegee blades for wear and rotate or replace them if needed. Adjust the squeegee if it's out of alignment. Make sure there's detergent in the solution tank to prevent squeegee chatter. Also, inspect for clogs in the vacuum hose or a dirty vacuum screen and clear them. Other potential issues include worn recovery tank cover seals (replace them), debris caught in the squeegee (remove it), a disconnected or damaged vacuum hose (reconnect or replace), or a recovery tank cover that isn't completely closed (check for obstructions and close properly).

What to do if my Tennant T20 Scrubber has poor scrubbing performance?

  Debra SmithAug 26, 2025
  If your Tennant Scrubber's scrubbing performance is lacking, there are several possible reasons. First, make sure the 1-STEP button is on. Check if the solution tank is empty and fill it if necessary. Also, inspect the main brushes for any caught debris and remove it. If the brushes are worn, replace them. Finally, the brush pressure might be set too low; increase it to improve scrubbing.

Why is there little or no solution flow from my Tennant T20 to the floor?
- R
  Richard JosephAug 26, 2025
  If you're experiencing little to no solution flow to the floor in conventional scrubbing mode with your Tennant Scrubber, first check if the solution tank is empty and fill it. Next, verify that the solution flow is turned on. If both are fine, the solution supply lines might be plugged, so flush them to clear any blockages.

Why does the ec?H2O system indicator light blink red and the alarm sound on my Tennant T20?
- T
  Tracy McclainSep 12, 2025
  If the ec?H2O system indicator light blinks red and the alarm sounds on your Tennant Scrubber, it could be due to mineral deposit build-up in the module. Flush the module. If the indicator light starts flashing within 1–10 seconds, repeat the flush procedure. If the indicator light starts flashing after a minute of scrubbing, the water may have low conductivity. In this case, add 8ml of salt to every 40 L of water.

  If the FaST system on your Tennant Floor Machine isn't working, first ensure the FaST button is turned on. Check the FaST?PAK supply hose and connector for clogs; soak them in warm water to clean. Verify the FaST?PAK carton isn't empty or disconnected, and replace or connect it as needed. Prime the system by operating it for a few minutes. Also, inspect the filter screen for clogs and clean it after draining the solution tank. For blown fuses or a faulty solution pump, contact a Tennant service representative.

Why is the ES System not operating on my Tennant T20 Scrubber?
- T
  Todd WalkerSep 6, 2025
  If the ES system on your Tennant Scrubber isn't operating, first check that the ES button is turned on. A dirty ES sensor in the tank could be the problem, so clean the sensor. Also, a clogged ES pump filter can cause issues, so clean the ES filter. Ensure the water level in the recovery tank isn't too low; fill it about half full. Finally, check that the water level in the solution tank isn't too low; fill the solution tank.
