TROUBLESHOOTING GUIDE
1. Valve does not function (red light does not flash when user
steps in front of sensor).
A. No power is being supplied to sensor. Ensure that the main power is
turned “ON.” Check transformer, leads and connections. Repair or
replace as necessary.
B. EL-1500 sensor is not operating. Replace the EL-1500 sensor.
2. Valve does not function (red light flashes when user steps in
front of sensor).
A. Red light stops flashing when user steps away and valve makes a
“clicking” sound but does not flush.
a. No water is being supplied to the valve. Make certain that the water
supply is turned “ON” and the Control Stop is open. No power is
being supplied to sensor. Ensure that the main power is turned “ON.”
Check transformer, leads and connections. Repair or replace
as necessary.
b. EL-128-A cartridge is fouled or jammed. Turn electronic power to
valve “OFF” (failure to do so could result in damage to the solenoid
coil. Remove the solenoid operator from the valve and remove the
EL-128-A cartridge. Clean and/or repair as necessary.
B. The red light stops flashing when user steps away but the valve does
NOT make a “clicking” sound and does NOT flush.
a. EL-163-A solenoid shaft assembly is fouled or jammed. Turn electronic
power to valve “OFF” (failure to do so could result in damage to the
solenoid coil). Remove EL-101 or EL-166 nut from the solenoid
operator. Remove the coil from the solenoid operator. Use a spanner
wrench or pliers to remove the EL-163-A solenoid shaft assembly from
valve. Clean and/or replace as necessary. Be sure to replace plunger
spring when reassembling solenoid shaft assembly.
C. The red light flashes three (3) short flashes, three (3) long flashes then
three (3) short flashes (“S-O-S”) and continues to repeat this cycle even
when user steps out of the sensor’s detection range.
a. EL-1500 sensor wiring connections are incorrect. Re-wire sensor to
valve. One solenoid lead connects to the “TO VALVE” connection on
sensor. One transformer lead connects to the “24 VAC IN” connection
on sensor. Second solenoid lead and second transformer lead connect
together.
b. Wiring to sensor is ground shorted. Find short in wiring circuit and
correct.
c. EL-165-2 solenoid coil is burnt out or coil is not connected to solenoid
plunger shaft. Reinstall or replace coil as necessary.
3. Volume of water is insufficient to adequately siphon fixture.
A. Control stop is not open wide enough. Adjust control stop for desired
water delivery.
B. Low consumption unit is installed on water saver or conventional fixture.
Replace diaphragm component parts of valve with kit that corresponds to
appropriate flush volume of fixture.
C. Inadequate water volume or pressure available from supply. Increase
pressure or supply (flow rate) to the valve. Consult factory for assistance.
4. Length of flush is too long (long flushing) or valve fails to
shut off.
A. Water saver valve is installed on low consumption fixture. Replace
diaphragm component parts of valve with kit that corresponds to
appropriate flush volume of fixture.
B. Relief valve in diaphragm is not seated properly or bypass hole in
diaphragm is clogged. Disassemble inside diaphragm component parts
and wash parts thoroughly. Replace worn parts if necessary.
5. Water splashes from fixture.
A. Supply flow rate is more than necessary. Adjust control stop to meet flow
rate required for proper cleansing of the fixture.
6. Leakage occuring at the push button.
A. Damaged or worn seals or lime build up in the actuator cartridge. Replace
with new HY-32-A cartridge.
7. The flushometer does not flush or flushes only once and will not
flush a second time when the button is pushed.
A. The plunger is lodged in the actuator cartridge or the plunger by-pass
hole is clogged. Remove the actuator housing and cartridge from the
flushometer. Clean under running water. If cartridge parts are worn,
deteriorated or limed up and problem persists after cleaning, replace with
new HY-83-A cartridge.
a. Turn off water at the control stop.
b. Unscrew the housing coupling nut from the flushometer.
c. Remove the actuator housing from the flushometer. The tubing
connections can be left intact.
d. Remove the actuator cartridge from the flushometer body. Care should
be taken so that upon removal the actuator does not abruptly separate
due to spring compression within. If the actuator cartridge is lodged in
the body cavity, grip the exposed portion gently with a pair of channel-
lock pliers and rotate back and forth to loosen the o-ring seal.
e. Separate the actuator housing to reveal the spring and plunger.
B. Plastic tubing installed incorrectly. Install Plastic tubing correctly.
8. The flushometer does not flush and a small amount of leakage
is visible below the valve.
A. Foreign material lodged in the cartridge. Remove the cartridge and inspect
for foreign material. Clean under running water.
B. Damaged or worn seals or lime build up in the actuator cartridge. Replace
with new HY-32-A cartridge.
a. Remove the button or actuator assembly from the wall or fixture.
b. Disassemble the flange or button assembly from the actuator body.
c. Unscrew the cartridge from the actuator body.
NOTE: The metal
push button was designed to be vandal-proof and thus
requires removal from the wall for servicing.
C. Plastic tubing installed incorrectly. Install Plastic Tubing Correctly.

NOTE: URINALS – When the sensor detects a user, a slow flashing red light appears in the sensor window. After eight (8)
to ten (10) seconds, the light flashes rapidly to indicate that the sensor is armed. When the sensor no longer detects a
user, the sensor immediately activates the solenoid valve after a 0.5 second delay.
WATER CLOSETS – Detection and activation are the same as for the urinal except when the sensor no longer detects an
user, the sensor activates the solenoid valve after a three (3) second delay.
LAWS AND REGULATIONS PROHIBIT THE USE OF
HIGHER FLUSHING VOLUMES THAN LISTED ON
FIXTURE OR FLUSHOMETER.
