another suggestion is what happened to the DL1s in the past when this error would not go away. try doing the factory default reset on the projector, then the fixture reset. This did the trick on one of my pesky Dl1 units, after replacing all air filters and the warning for new hepa filter would still show up. atleast it is worth a try.
