Hello, I am a newer Biomed and am having some issues with one of my machines. Its a 2008T machine with bibag and I am constantly getting bicarb condo 2 high, this machine has 8972 hours on it and the previous biomed who was having the same issue had replaced the whole entire bibag assembly including all valves, boards, transducers everything. All of those have been replaced within the last two months, all hydraulics were rebuilt and calibrated, bicarb condo cell calibration, bicarb volume calibrated, pressure transducers 110 and 109 replaced. so pretty much anything to do with bibag system has either been replaced, tested or recalibrated. it runs fine on a jug but not with bibag, the machine lasted two weeks before having the bicarb condo 2 high come back and I am not really sure where else to look, because there really isn't to much in depth information when it comes to bibag error messages. The previous biomed also spoke to Fresenius tech support and did what they said and it still hasn't worked, I am hoping that maybe someone has had this before and figured out the cause because I am not sure what else to look at! I have thought about following trouble shooting guide for conductivity to see if maybe through that section something may pop up that connects to bibag system. Figured id ask advice here first! Thank you in advance!

I'd check your loading pressure. When the machines run on Bibags there is a calibration that is done to fix bicarb cond high and low by adjusting the loading pressure to bring TCB(therorical conductivity of bicarb) inline with BIC MON.... by adjusting the pressure you adjust BIC MON to match as close as possible TCB. I believe the screen is tech screen 15(top left hand side of the screen) TCB, bic LOW, bic mon and bic high.... With a bag on you will see a value show up in BIC MON.
You wont see it without the bag. Adjust the loading pressure to change the value of BIC MON to get as close to TCB as possible. Once completed verify your loading pressure is still within specs.... I usually adjust my loading pressure to max first then do the calibration from there meaning i can only turn it down or counter-clockwise. BIC LOW and BIC High are your alarm limits. Hope this helps

Ok I will give that a shot today! I did notice that machine was stuck trying to calibrate temp it would not go higher than 32 so I am going to check heat exchanger and heating rod, that could mess up conductivity if temp is not correct right? I will do what you said above and fix the temp problem and give it a shot! I will post the fixes after! Thank you for your guidance!

Ok so I got the BIC MON as close to TCB as possible and recalibrated temp sensors and so far running the machine with bibag for the last 3 hours and no bicarb condo 2 high alarm anymore!!! Cant thank you enough for your help!!!

OK, so I just tried to perform the repair method that pacnw posted and this did not work for me. Bic Mon at 663 and did not move when tried adjusting loading pressure. TCB=300, Bic lo=255, Bic Hi=345 and bic mon cond=663 (never got it to move). Seems like the bic condo is in the middle of the road for me and am curious why the bicarb condo 2 high alarm is showing up. As a matter of fact, it went from "bibag condo 2 high" to "bibag PHT failure" upon minute adjustments to loading pressure made at a time. Maxed out loading pressure and tried to adjust down while looking at debug 15. Unless I am missing something, the posted fix may not work for everyone. There really needs to be a legitimate tshooting guide for the bibag system..

There really needs to be a legitimate tshooting guide for the bibag system.. Youre alarming becasue your bic mon 663 is above the bic hi of 345. Hi is you upper alarm limit... are you doing this with the bibag installed? I've never seen the bic mon that high! |

You need to also calibrate your Bicarb Cell.

FYI: The Bluestar software (either standard or premium) has a much wider alarm range for bicarb conductivity. For years I had problems and could never really do anything to fix it (the machine would work for me). As soon as we upgraded to the Bluestar (standard) software, I never saw the dreaded "bicarb cond. high 2" alarm ever again.

Seeing a similar issue. Bic con Mon is about double that of TCB. Tried calibration and the calibration failed. Replaced condo cell and calibrated…failed again. Any suggestions?

You want to get TCB as close to bic mond by adjusting the loading pressure.Did you do a condo cell calibration or bicarb cell calibration? Bicarb cell calibration usually always fixes it for me. Than i go into dialysis mode and see the tcb and bicarb mond and adjust if needed. If you still get the issue than something is going on with the bibag distribution board at least in my experience.

I didn't want to believe it, but I was having this alarm on a 2008T, 4T-series. Tried to cal bic cell, error. Changed cell and tried recal, error. Alarm Hi was at 345 and my monitor was hitting 360 and going up to 410. Looked for leaks/air, reseated boards and it would pass ALL tests and then alarm for Bicarb Condo 2 High.
Reluctantly pulled the Deaeration motor, cracked it open and I bet the Great Pyramids have less dust in them (albeit not carbon). The brushes were down to *maybe* 1/4"! Changed brushes, cleaned the motor casing and once reassembled and Deaer/Ldg cal'd....Bic Mon is sitting just a few digits off of TCB.
I once worked with someone who said "Never underestimate the power of changing the d@mn brushes."
Point well-taken.

I had this issue and replacing loading pressure valve fixed it

Any time you adjust or replace the loading pressure valve on a bi-bag machine, you must calibrate the bicarb conductivity cell.
