Error Code Pump Fault

A pump fault has occurred and no watering will occur.

? What Causes This

A defective solenoid on the master valve, incompatible or defective pump start relay, or wire run between timer and relay is too long.

✓ How to Fix It

Conduct a resistance check on the circuit. If using a pump start relay, check wire size and run to the relay, verify it is working, and ensure good wire connections. Clear the fault by turning the dial from AUTO to another position then back to AUTO, or by running a manual cycle.
