Troubleshooting Q&A

Below is a Troubleshooting Q&A Guide for the EBF-665, EBF-775, ETF-660, and ETF-770 Electronic Faucets from Sloan. This guide highlights the most commonly occurring problems and how to go about fixing them. As always you can call us for assistance or if you need to replace a part and/or unit.

1

PROBLEM:
LED Indicator light in the IR (infrared) sensor is red

CAUSE:
A) Battery power is low

SOLUTION:
A) Install four (4) new "AA" sized alkaline batteries. Check that the orientation of each battery matches the positive (+) and negative (–) symbols that are shown in the bottom of the battery compartment. Re-attach battery compartment to the control module. Green LED will illuminate. If the Green LED does not illuminate, remove battery compartment for 10 seconds and then re-attach.

2

PROBLEM:
Faucet DOES NOT function

CAUSE:
A) Batteries not installed or are exhausted

B) Power Cable not installed (Hardwire models)

C) Sensor Cable not installed

D) Sensor range is set too short and is not detecting the target

SOLUTION:
A) Install four (4) new "AA" sized alkaline batteries. Check that the orientation of each battery matches the positive (+) and negative (–) symbols that are shown in the bottom of the battery compartment. Re-attach battery compartment to the control module. Green LED will illuminate. If the Green LED does not illuminate, remove battery compartment for 10 seconds and then re-attach.

B) Install power cable and check connection

C) Install sensor cable and check connection. Confirm connection guide markings are aligned.

D) Increase sensor detection range.

3

PROBLEM:
Sensor is activated but faucet DOES NOT deliver water

CAUSE:
A) Faucet has initiated its adaptive sensing calibration program

B) Solenoid cable is not connected

SOLUTION:
A) Wait 60 seconds before activating the faucet

B) Check the solenoid cable connection. Confirm connection guide markings are aligned.

4

PROBLEM:
Sensor Range Requires Manual Adjustment

Sensor Range is measured in units from 1 to 5, with 1 being the closest to the faucet and 5 being the farthest from the faucet. The factory default sensor range is 3.

SOLUTIONS:
A) To determine what the current Sensor Range setting is, press the red "Sensor" button on the upper right hand corner of the Optima Control Box for 1 second. Five seconds after pressing the button, the green LED beside it will blink to indicate the Sensor Range setting. For example, if it is set at 2, the Green LED will blink 2 times.

B) To adjust the Sensor Range, press and hold the red "Sensor" button for three seconds and release once the Green LED comes on to indicate that you are in Sensor Range adjustment mode. Then press the "Sensor" button one second at a time for however many times you wish to increase the range. For example, if the Sensor Range is set at 2 and you wish to increase it to 4, press the "Sensor" button two times for one second each time.

C) If you wish to decrease the Sensor Range, follow the same procedure to enter into Sensor Range adjustment mode, and then press the "Sensor" button one second at a time. The button is designed to go up to 5 units and then back down to 1 unit. For example, if the Sensor Range is set at 4 and you wish to decrease it to 2, press the "Sensor" button three times for one second each time.

D) To confirm your changes, wait 5 seconds and then press the red "Sensor" button on the upper right hand corner of the Optima Control Box for 1 second. Five seconds after pressing the button, the Green LED beside it will blink to indicate the Sensor Range setting. For example, if it is now set at 2, the Green LED will blink 2 times.

5

PROBLEM:
Solenoid produces an audible "CLICK" when an object is placed in the detection zone of the sensor but NO water flows.

CAUSE:
A) Water supply to faucet is not open

B) Inlet fitting filter is clogged

C) Aerator or spray head is clogged

SOLUTION:
A) Open supply stop(s).

B) Remove, clean, and reinsert. Replace with EBF-1004 (#08578) solenoid filter kit if necessary.

C) Remove, clean, and reinsert.

6

PROBLEM:
Solenoid valve DOES NOT produce an audible "CLICK" and NO water flows. Green LED illuminates when batteries installed.

CAUSE:
A) Solenoid valve module is not working properly.

SOLUTION:
A) Replace EFP-43-A solenoid valve module.

7

PROBLEM:
Faucet delivers only a slow flow or dribble when sensor is activated.

CAUSE:
A) Water supply to faucet is not open

B) Inlet fitting filter is clogged

C) Aerator or spray head is clogged

SOLUTION:
A) Open supply stop(s) completely.

B) Remove, clean, and reinsert. Replace with EBF-1004 (#08578) solenoid filter kit if necessary.

C) Remove, clean, and reinsert.

8

PROBLEM:
Faucet DOES NOT stop delivering water or continues to drip after user is no longer detected (automatic shut-off fails even when batteries are removed).

CAUSE:
A) Solenoid valve seat is dirty.

B) Sensor range is set too long and is detecting the sink or some other object.

C) Solenoid valve module is not working properly.

SOLUTION:
A) Remove, clean, and reinsert solenoid filter. Activate faucet several times to flush out dirt.

B) Reduce sensor detection range.

C) Replace EFP-43-A solenoid valve module.

9

PROBLEM:
The water temperature is too hot or too cold on a faucet connected to hot and cold supply lines with inlet filter fitting.

CAUSE:
A) Supply stops are not adjusted properly.

SOLUTION:
A) Adjust supply stops.

NOTE: For some systems, a thermostatic mixing valve may be required.

 

Care and Cleaning Instructions
DO NOT USE abrasive or chemical cleaners (including chlorine bleach) to clean faucet that may dull the luster and attack the chrome or special decorative finishes. Use ONLY mild soap and water, then wipe dry with clean cloth or towel. While cleaning the bathroom tile, protect the faucet from any splattering of cleaner. Acids and cleaning fluids will discolor or remove chrome plating.
