What to do if no water comes from the Toto Control Unit flush valve?
- H
  Hannah HallJul 27, 2025
  If no water is coming from the flush valve, there could be several reasons. First, check if the main valve in the water supply line or the control stop is shut off and open it. Make sure all cables are correctly connected. Inspect the glass in front of the infrared sensor; if it's dirty, clean it. Also, ensure there isn't a reflective surface in front of the sensor. Finally, the small holes in the solenoid diaphragm may be clogged, clean the small hole in the diaphragm and filter; or the hydropower generator may be clogged, service the hydropower generator.

Why does my Toto Control Unit keep running water?

  If the water doesn't stop flowing, it could be due to several reasons. Check if the small hole in the piston is clogged and clean it. Also, the sealing area of the piston or the solenoid diaphragm might be dirty, so clean those areas and the filter. Finally, inspect the piston u-packing for damage and replace it if necessary.

Why is the flow rate too low in my Toto Control Unit?
- Q

  If the flow rate is too low, it might be because the water supply pressure is too low (below rated minimum pressure). Also, check if the control stop is not open enough and adjust it properly.

  David AndersonAug 17, 2025
  If the flow rate is too high, it is likely that the control stop is not adjusted properly. Adjust the control stop accordingly to decrease the flow.

What does it mean when a red light blinks in the sensor window of my Toto Control Unit?
- J
  Jay YangAug 22, 2025
  A blinking red light in the sensor window indicates that the battery is weak. Check the voltage with a multimeter; if it's below 2.6 V, contact TOTO for a replacement battery.
