I have had a machine down for a while that I just can't figure out. EO2 displayed on the blood pump. Display on machine says art bp no comm.
I have tried a working test board, function board, swapped in a brand new blood pump, tried swapping the board from the new blood pump in the old blood pump, and even tried the power supply on a hunch.
thank you all for your responses. I figured I would ask here before calling Fresenius tech support this morning. This is the third machine that has done it so if they are replacing with no charge I guess I should have explained the problem to them first.
They are trying to figure the problem out in Germany. It is your LP955 board. They keep getting a bunch of bad ones. I just replaced 4 in the last 2 weeks. The issue keeps coming up with E.02 E.03 E.05.
Bad LP955 boards have been the bane of my existence ..well one of many.. on the new T's. When they first started acting up I would call up tech support and get new boards sent..half of those were rubbish too! I wised up and when I was getting ready to send my old k2's off for disposal on this last go round..I took every last LP955 board off of them.
