Narrative:

Captain flying; cleared to intercept ILS 1 dca; autopilot on; map indicated we were well left of course; as localizer came right to left; indicating we were crossing final. Airplane began a right hand turn; which would be the wrong direction. Captain turned autopilot off and attempted to intercept final. We discussed the contradictory information presented to us and decided to go-around at 3000 ft. Second approach was basically the same; data presented was contradictory; so we went around again. Third attempt was done via a VOR approach; which proved to be reliable. We wrote it up as an ILS receiver malfunction.
