Watermaster 57114 Timer: Whining Noise, No Valve Activation

Orbit Watermaster Timer Hums but Valves Don't Open

Watermaster 57114 (Orbit) programmed weekly. Now manual mode: low whine per zone, advances, nothing happens. Wires look fine. No outdoor shutoffs touched.

Unfamiliar Timer—Basic Checks

1. All water valves ON? Check source valve and backflow preventer valves.
2. Transformer hum? The whine may be the transformer. If no 24VAC output, timer is dead.
3. Orbit support – Check Orbit's website for manual/troubleshooting.

If valves have water and timer has power but no output, replace timer. Orbit timers are inexpensive.
