Problem: The valve will not open electrically #
First, run the valve manually by opening the manual bleed lever/screw (turn counterclockwise). Close the manual bleed lever/screw when the manual test is complete.
Check if…
- The valve is installed incorrectly – Make sure that the arrows are in the direction of water flow.
- Wiring is incorrect – Check wiring at the valve and at the timer with the instructions Check to see that timer is working properly.
- There is debris in the porthole – Turn off water. Remove the solenoid. Push a wire or large paper clip down through the round porthole working it up and down to free any debris. Be sure the plunger and O-ring are in place when reassembling.
- Defective solenoid – Turn off water. Unscrew the solenoid and replace it with one from a working valve. If the valve works, replace the solenoid. Be sure the plunger and O-ring are in place when reassembling.
- Solenoid plunger is stuck – Turn off water. Remove the solenoid and clean out sand and debris. Be sure the plunger and O-ring are in place when reassembling.
