Aircraft
Prior to boarding; I turned on the APU bleed valve. Shortly afterwards; the #1 Flight Attendant informed me of a wide spread dirty sock odor reported by multiple inflight crew members. The odor recognition procedure directed me to deselect the APU bleed and complete a logbook entry. Maintenance took the aircraft out of service after the odor persisted during their initial troubleshooting.
Air carrier pilot reported; while at the gate; turning on the APU bleed valve. The aircraft began to fill with the dirty sock odor. Maintenance action was required.
