I have a Bluestar machine with 27,000+ hours. They just began using the bibag system in October 2023. I have had a bibag temp sensor error now for the last week. I have calibrated the temperature, replaced thermistors 3, 114, and 116, changed battery on function board. I swapped the function board and sensor board with a good machine and the error followed. There was no error in the "bad" machine when I put the other boards in. When I put in a new function board the error was no longer there when I started up the machine. After I did all the necessary calibrations the error appeared. I also replaced the sensor board. I recently replaced the sensor board as well and completed all the necessary calibrations and the error still appears on start up. I used liquid bicarb to see what would happen in dialysis mode. Everything was fine until I went to test. Got a V104/108 stuck closed error. I figured that would happen. I am at my wits end with this thing. I'm not understanding what else the problem could be since the error traveled to the other machine when I swapped boards. Please help.

Personally I would try looking at the center bibag hydraulic kit and swapping that with a known good.

Bibag temp sensor error is an advisory error according to the operator's manual. That being said on debug screen 14 there is a box (temp senr) that records whether there is a temp sensor error (according to the debug screen sheet) It also says that this is reset during rinse. (operators manual also states to put machine through rinse until error clears) (could be why switching the function and sensor board switch worked temporarily) Also on debug 14 the temperature is shown for temp sensor 114 you could compare your "broken" machine to that of a good machine to see if the temperatures are similar or if the broken one is way off. Could be that ntc 2 is acting up which is giving you an incorrect hydrochamber temp which directly feeds into the bibag and would affect the temp at 114. It is also good when calibrating temp when using bibags to not use liquid bicarb during the temp calibration. Since the bicarb from the bibag would be warmer than what would be coming from a jug at room temp. As for the 104/108 error when using liquid bicarb, that could be a number of things from stuck valves, pressure transducers, etc. I would look and figure out why you're getting the 104/108 stuck closed error before tackling the temp sensor error, as that could be the real reason your getting the temp error.

It turned out to be V100. I really do not understand how that was the issue since I swapped boards around and the error followed to the other machine. I have been basing all my trouble shooting off of that happening.
