try doing a full bleach disinfection first, then recalibrate blood leak detector. Or, maybe you have a wet transducer leading to the board

MACHINE UNABLE TO PUT INTO BLEACH DISINFECT, STILL SAYS BLOOD STILL SENSED, WHEN IT SAYS STANDBY FOR TEST ITS YELLOW AND WILL NOT LET IT GO INTO TEST I HAVE TRIED TO GO TO NEW TX IT WILL NOT LET ME DO ANYTHING. NEW TECH HERE BEAR WITH ME
See if you have a loose ribbon wire on the air detector module or at the card cage. If that doesn't do it try a different air detector module. "Blood Still Sensed" is usually just a loose cable somewhere.

checked all ribbons and cables everything seems to be ok. im going to try to change out the power supply i guess when this all first started they were in icu and lost power first then when they brought the machine upstairs it was saying blood still sensed. if you have other ideas thats great

When the machine is powering up, does it alarm and not stop? If so, definite electronic problem. I had this problem a few years back and thought it too was the sensor board or the level detector module. It was the function board. If you have the electronic diagrams from level II training, look at Diagram F - Monitors and Alarms. You will see that the Blood Sensed goes from the Level Detector (FF) straight into the Functional Board, and the trail finally ends in the Power Logic Board. You've swapped out everything else so now try the Functional Board.

FUNCTION BOARD IT WAS THANK YOU MUCH

Forgot to add (seeings as you're new), don't forget to transfer the chip with all your calibrations from the Functional Board you're replacing to the new Functional Board.
I should also add that the "Blood Still Sensed" and the blood leak detector are two completely different animals. Calibrating one doesn't fix the other. Just so you know.
