1. PROBLEM:
Valve does not function (red light does not flash when
user steps in front of sensor).
CAUSE:
No power is being supplied to sensor.
SOLUTION:
Ensure that the main power is turned “ON.” Check
transformer, leads and connections. Repair or replace as
necessary.
CAUSE:
EL-1500/EL-1500-L Sensor is not operating.
SOLUTION:
Replace EL-1500/EL-1500-L Sensor.
2. PROBLEM:
Valve does not function (red light flashes when user
steps in front of Sensor).
INDICATOR:
Red light stops flashing when user steps away and
valve makes a “clicking” sound but does not flush.
CAUSE:
No water is being supplied to the valve.
SOLUTION: Make certain that water supply is turned “ON” and the
Control Stop is open.
CAUSE: EL-128-A cartridge is fouled or jammed.
SOLUTION:
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.
INDICATOR:
The red light stops flashing when user steps away but
the valve does NOT make a “clicking” sound and
does NOT flush.
CAUSE: EL-163-A solenoid shaft assembly is fouled or jammed.
SOLUTION:
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.
INDICATOR:
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.
CAUSE: EL-1500/EL-1500-L Sensor wiring connections are
incorrect.
SOLUTION:
Rewire 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.
CAUSE:
Wiring to Sensor is ground shorted.
SOLUTION:
Find short in wiring circuit and correct.
CAUSE:
EL-165-2 solenoid coil is burnt out or coil is not
connected to solenoid plunger shaft.
SOLUTION:
Reinstall or replace coil as necessary.
3. PROBLEM:
Volume of water is insufficient to adequately siphon
fixture.
CAUSE:
Control Stop is not open wide enough.
SOLUTION:
Adjust control stop for desired water delivery.
CAUSE:
Low Consumption unit is installed on Water Saver or
Conventional fixture.
SOLUTION: Replace Diaphragm component parts of valve with kit
that corresponds to appropriate flush volume of fixture.
CAUSE:
Inadequate water volume or pressure available from
supply.
SOLUTION:
Increase pressure or supply (flow rate) to the valve.
Consult factory for assistance.
4. PROBLEM:
Length of flush is too long (long flushing) or valve fails
to shut off.
CAUSE:
Water Saver valve is installed on Low Consumption
fixture.
SOLUTION:
Replace Diaphragm component parts of valve with kit
that corresponds to appropriate flush volume of fixture.
CAUSE:
Relief valve in diaphragm is not seated properly or
bypass hole in diaphragm is clogged.
SOLUTION:
Disassemble inside Diaphragm component parts and
wash parts thoroughly. Replace worn parts if necessary.
5. PROBLEM:
Water splashes from fixture.
CAUSE:
Supply flow rate is more than necessary.
SOLUTION:
Adjust Control Stop to meet flow rate required for proper
cleansing of the fixture.
CAUSE:
Closet valve is installed on urinal fixture.
SOLUTION:
Replace closet Diaphragm component parts with proper
urinal kit (Inside Diaphragm Assembly or Inside Parts Kit)

Troubleshooting Guide
NOTE:
Upon detection of the user, the red indicator light flashes
slowly
for a period of eight seconds. When the user leaves the detection range, the indicator light flashes
rapidly
and the Sensor initiates the flush sequence. Then the indicator light
stops
flashing and the valve flushes. (On water closet models, the valve will flush after
a three-second delay).
Maintenance Guide
Care and Cleaning Instructions
DO NOT USE abrasive or chemical cleaners to clean Flushometers that may
dull the luster and attack the chrome or decorative finish. Use ONLY soap and
water, then wipe dry with a clean towel or cloth. When cleaning the bathroom
tile, protect the Flushometer from any splattering of cleaner. Acids and
cleaning fluids can discolor or remove chrome plating.

Control Stop Setting
IMPORTANT:
Never open Control Stop to where the flow from the valve
exceeds the flow capability of the fixture. In the event of a valve failure, the
fixture must be able to accommodate a continuous flow from the valve.
