WFCO error code Red blown-fuse LED on the DC fuse board
The DC branch fuse beside that LED has blown because the circuit drew more current than the fuse rating. WF-8500-AD: 13 circuits each with a red LED; WF-9500-AD: 17 circuits; WF-8700-AD: 4 (WF-8725-AD) or 6 (WF-8735/8740-AD) circuits with surface-mount LEDs that are barely visible to the naked eye.
What to check, and in what order, is in the app. A step-by-step flow walks this code with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
