This morning I discovered that my sprinklers didn't work this morning. When I looked at the controller it was flashing 2FUS. The system is about 10 years old. The trouble shooting manual on the web states that there are crossed wires or a bad valve. I looked at the connections and all of them look good and tight. Shouldn't the valves work, except for the bad one? I tested the pump and it is working fine. Any ideas on how to go about diagnosing and correcting this problem?
Thanks JD
