Possible Solution
Make sure the main water line and all supply
lines are open and operating properly.
Flush the valve of debris by temporarily opening
the dump hole. Retighten after flushing is
complete.
Make sure all field wires and master valve/pump
start relay wiring is connected properly.
Check field wiring for broken, cut, or "skinned"
wires and replace if necessary. Check all wire
connections and replace with watertight splice
connectors as needed.
Make sure the dial is on AUTO RUN—not any
other dial position.
You can either wait until the Rain Sensor dries
out, or disconnect the Rain Sensor from the
yellow terminals on the timer and replace it with
a wire connecting the two yellow terminals.
Connect the two yellow Rain Sensor terminals in
the timer's terminal bay with a short length of 14
to 18 gauge wire.
Press the reset button under the wiring cover. If
there is no permanent damage, the timer should
resume normal operation. You will need to input
the correct time and date, but your watering
schedule should remain intact.
Possible Solution
Make sure the two-prong connector is connected and the
transformer is securely plugged in.
Make sure the main AC power supply is working properly.
Unplug the timer for 3 minutes. Plug the timer back in.
If there is no permanent damage, the timer will accept
programming and resume normal operation.
Replace transformer.
