TROUBLESHOOTING
Note: Before performing any service or troubleshooting, turn off the water supply at the control stop and if possible, flush out remaining water in the flushometer.
1. The Sensor is Not Detecting a User, or the Valve is Not Flushing.
a.
The batteries may need to be replaced – check to see if the sensor light is blinking. If it is, replace the batteries before proceeding with the below.
b.
The electronic sensor module may need to be replaced. A repair kit is available to do this. See repair parts section of this installation manual for the part number.
c.
Try replacing the potentially faulty sensor module with a working one from another unit first as a test.
i.
If the replacement works, then the problem lies with the sensor module and a repair kit should be ordered.
ii.
If the replacement does not work, then the problem may lie with the solenoid. Follow below troubleshooting steps to diagnose.
d.
Listen for an audible click from the solenoid after obstructing the lens for 6 to 7 seconds.
i.
If there is an audible click, then there may be debris in the valve body that is preventing the piston from moving. Wash the piston and valve body under running water.
ii.
If there is no audible click, then the solenoid may be stuck in the closed position. Order a replacement solenoid. See repair parts section of this installation manual for the part number.
2. The Red Sensor Light is Blinking Once per Second.
a.
The batteries are running low. We recommend replacing the batteries.
3. The Red Sensor Light is Blinking Twice per Second.
a.
The batteries have been used up. The batteries must be replaced.
4. The Flush Valve is Flushing Continuously or Does Not Shut Off.
a.
Check for an audible click from the solenoid.
i.
If there is an audible click, proceed with troubleshooting step 4.b
ii.
If there is no audible click, order a replacement solenoid.
b.
The bypass in the valve body is likely clogged with debris or build-up from the water supply. Remove the valve body and all internal components. Note that there is a small spring which acts as a filter
inside of the bypass. Remove this by turning the valve body upside-down. Wash the filter under running water. Wash the inside of the valve body, including the bypass, under running water.
5. Not Enough Water is Being Supplied to the Ceramic Fixture.
a.
Ensure that the correct model of flushometer has been installed. (e.g., ensure a 1.28 GPF flushometer has not been installed to a 1.6 GPF toilet)
b.
Ensure that the control stop is adjusted properly. Open the stop further to allow for more water flow.
c.
Ensure the supply has enough pressure to support the flushometer.
6. Too Much Water is being Supplied to the Ceramic Fixture.
a.
Ensure that the correct model of flushometer has been installed. (e.g., ensure a 1.6 GPF flushometer has not been installed to a 1.28 GPF toilet)
b.
Ensure that the control stop is adjusted properly. Close the stop further restrict flow.
7. Flushometer Performs a Flush Cycle on its Own With no User Present.
a.
The flushometer is designed to perform a courtesy flush once every 24 hours. This behavior is normal.
b.
If the behavior happens more frequently, ensure there is nothing obstructing the sensor lens. Try wiping the lens clean if no physical object is creating an obstruction.
