My 2008H machine has a blood leak alarm that wont clear.I have put the machine through a bleach disinfect and calibrated the detector and the dimness.I also changed out the blood leak detectror with a new one and still the alarm will not clear.
Has anyone had this problem?and what did you do to fix it.
Thanks everyone.

might wanna see if you have huge air bubbles actually going through your blood leak detector.

Does the alarm never reset, or just alarm after a few minutes of operation? I had a problem recently with an intermittent blood leak. It would calibrate fine but alarm consistently after 1-2 hours of use. I was fortunate enough to have my data-logging DVM and I found that both the 5V blood leak and dimness would jump between 2V and Overload for no reason. I was monitoring this on the Sensor Board. Replaced with new Sensor Board and problem solved.

You could monitor those voltages on the Debug screen as LEAK and DIMN, but im not sure they would react in the same way.

I replaced the bloodleak detector and the sensor board. I bleached but the blood leak will not calibrate it goes from 0 to 12.00 there is no visible air entering or exiting the blood leak detector.
Any suggestions????

Sounds like functional bd( battery ram ) is not holding the calibration. Had that problem on a 2008H a few years ago. Good Luck

I had the same problem before. So I changed with a new blood leak detector. I spent a month still cann't fix it.

Finally, I made it to work. I replaced it with another brand new blood leak detector.

Sensor board maybe, but your problem is more symptomatic of a bad detector. We had 5 new "K" machines with the same exact problem. Replacing the detector corrected the problem.

try calibrating the air detector.

Why would the air detector have anything to do with blood leak.

I replaced the blood leak detector and also the sensor brd and calibrated the blood leak detector.
but when its in test it fails blood leak detect.not cal.
anyone have any other suggestions??
Thanks for all the help everyone.

Try a known good function board.

Try a new test brd.

This may be a stupid question and I don't mean to insult your intellegence, but have you tried following the troubleshooting guide? It was pretty helpful for me the last time I had a problem with a blood leak detector.

Did you check air as 17IRISH recomended?
I have had in the past bad air separator if it is old 2008H

Yes i checkeed for air and there wasnt any visable.also this is happening with a lot of my 2008h lately. I am starting to loose my mind...
