I finished an annual on this machine about a month ago and since then it fails diasafe test.
My pressures are in spec, replaced the UF pump, changed the whole Diasafe holder+ filter, Replaced the V28, rebuilt V24, V26. Put machines back to back and verified that its not an electrical/board issue.
I am starting to go a little crazy.
The issue I am seeing is in dialysis mode everything works fine. Passes self test, simulated treatment with no issues, ect.
Once I go to diasafe test the TMP shoots up to over 600, sometimes even over 800. Then fails. I have a feeling there is a flow issue because when I try to do dialysate pressure cal, the bobber barely moves. But during treatment or rinse it moves fine.
I just for the life of me cant figure out where it might be.
