  If the FaST system on your Tennant Scrubber isn't working, first ensure the FaST button is turned on. Check for clogs in the FaST--PAK supply hose and connector, cleaning them in warm water if necessary. Verify that the FaST--PAK carton isn't empty or disconnected, replacing or connecting it as needed. The system may also need priming; operate it for a few minutes to prime it. Lastly, check the filter screen for clogs and clean it after draining the solution tank.

  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.

What to do if the scrub vacuum fan will not turn on in Tennant Floor Machine?
- P
  Pamela HamiltonSep 4, 2025
  If your Tennant Floor Machine's scrub vacuum fan won't turn on, start by checking if the vacuum fan/squeegee button is activated. A full recovery tank can also prevent the fan from starting; drain the tank to resolve this. Foam filling the recovery tank can cause issues, so empty the tank. Consider using less detergent or a defoamer to prevent foam build-up. Lastly, a dirty or stuck recovery tank sensor might be the culprit; try cleaning or replacing the sensor.

Why is my Tennant Floor Machine leaving water behind?
- L
  Lisa TaylorSep 2, 2025
  If the Tennant Floor Machine isn't picking up water, several factors could be at play. First, ensure the scrub vacuum fan is turned on. Check the squeegee blades for wear and rotate or replace them if needed. Make sure the squeegee is properly adjusted. Insufficient detergent can also cause squeegee chatter, so add detergent to the solution tank. Examine the vacuum hose for clogs and flush them out if necessary. Clean the vacuum screen and replace any worn recovery tank cover seals. Remove any debris caught in the squeegee. Finally, inspect the vacuum hose for disconnections or damage and reconnect or replace it as needed. Also, ensure the recovery tank cover is completely closed and free of obstructions.

Why is the ec?H2O system indicator light blinking red and the alarm sounding on my Tennant Floor Machine?
- J
  Jessica ParkSep 2, 2025
  If the ec?H2O system indicator light on your Tennant Floor Machine blinks red and the alarm sounds, 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 it flashes after a minute of scrubbing, the water may have low conductivity, in which case you should add 8ml of salt to every 40 L of water.

  If your Tennant Floor Machine isn't scrubbing well, make sure the 1?STEP Scrub button is on. Check if the solution tank is empty and fill it if needed. Remove any debris caught on the main brushes and replace the brushes if they are worn. Increase the brush pressure if it's set too light. For improper detergent or brushes, contact a Tennant service representative.
