## Discrepancy

DURING FLIGHT,  ECAM SHOWED A FWS AMBER FAULT MESSAGE.  SOON AFTER,  ECAM WARNING SYSTEM STARTED TO CYCLE  THRU MULTIPLE WARNINGS & CAUTIONS.  NORMAL CANCEL &  EMERGENCY CANCEL BUTTONS WOULD NOT CANCEL WARNINGS &  CAUTIONS.     REPLACED THE NR 1 FWC 1WW1 IAW AMM 31-53-34-04,  ECAM  DISPLAY TEST AND OPERATIONAL TEST OF ECAM SYSTEM  WAS GOOD.  ALSO SUCCESSFUL AFS LAND TEST. ACFT OK  FOR SERVICE.
