Problem Cause Solution
TouchTime push
button unit does
not function
properly.
Water supply or power not on. Make sure the water supply and the 24 VAC power are
both turned on.
Improper wiring Check wiring.
1. Turn the electrical power off.
2. Check the wiring for loose connections or corrosion,
correct if necessary.
3. Turn the electrical power back on and retest the
push button.
Transformer not functioning properly. Test the transformer with a volt meter.
1. Turn water supplu off (electrical should remain on).
2. Set the colt meter scale to be able to read "24
VAC".
3. Connect the volt meter leads from the transformer.
4. The voltage reading should indicate 24 VAC ±10%.
If you are unable to obtain a proper voltage reading,
the transformer is not working properly and needs to be
replaced. Contact your Bradley representative to order a
replacement transformer.
Solenoid valve not functioning properly. Test the solenoid valve.
1. Disconnect the green/gray wires from the solenoid.
2. Disconnect the brown transformer leads from the
terminal block.
3. Connect the brown transformer leads directly to the
solenoid. The solenoid coil should activate and you
should hear a single click and a humming noise.
4. If the solenoid still does not function, turn off
electrical power. Then remove the four screws that
secure the clamping plate to the valve body. Be
careful not to lose the armature or spring.
5. Remove the diaphragm and clean it gently but
thoroughly. Hold the diaphragm up to a light and
find the small hole which is located about halfway
between the inner and outer diameters. Make sure
the hole in the diaphragm is not plugged.
6. Reassemble the valve in reverse order and test
again with power from the transformer.
If the solenoid coil doed not activate, the solenoid valve is
not working properly and needs to be replaced. Contact
your Bradley representative to order a replacement
solenoid valve assembly.
TouchTime Troubleshooting
Make sure there is electrical power going to the transformer
and there are 24 volts coming from the transformer.
WARNING! Be sure to turn off electrical and water supplies
during troubleshooting.
If, after checking the transformer, the solenoid valve and the wiring, you are unable to activate the sprayhead
by pressing the TouchTime push button, the TouchTime switch assembly is not working properly and needs
to be replaced. Contact your Bradley representative to order a replacement switch assembly.
