Troubleshooting
Control Circuit
Faulty coil
Low voltage
Incorrect pressure
Excess leakage
: Listen for a metallic click when energizing the solenoid. Absence of the click
indicates loss of power to the solenoid. Check for loose connections, blown
fuses, open or grounded coil circuit, and broken lead wires.
: Check for open circuit in coil. Replace coil if necessary.
: Voltage across coil leads must be at least 85% of nameplate rating for proper
operation.
: Pressure to valve must be within range specified on nameplate.
: Disassemble valve and clean all parts. Replace all worn parts for best
results.
