Problem

Checking Method

Solenoid will not open

Is water turned on at mains

Is pump operating

Is valve flow control stem open or closed

Is valve installed with flow in correct direction. Valve will operate continuously if valve installed in wrong direction

Is power on at automatic controller

Is power getting to solenoid valve coil

Inlet port at top of valve is blocked. Remove bonnet of valve & clean port

Automatic controller not getting voltage to solenoid coil

Check controller output voltage. Return controller to Mid-West Irrigation for assessment. Replacing modules or front panel can fix problem

Solenoid coil not operating

Replace with new coil

Wire connections not waterproof or faulty

Replace wire connectors with waterproof connectors & check that wiring has not turned green due to moisture. If so replace wire. Copper wire turned green will not operate correctly as moisture ingress will impede or stop the electrical current flow from controller to solenoid valve

Solenoid valve leaking or staying ON

Particles of debris under diaphragm. Remove top of solenoid valve & clean diaphragm & diaphragm seat

Torn diaphragm. Replace

Manual bleed turned on
