I've got 5 two month old machines, each is repeatidly giving "uf pump test will be repeated" Of course when I try to run a mock treatment to diagnose it they all work perfectly. BBraun said the ufp_s wasn't reading and it could be; hall sensor wiring power board motors
This might not be making me scratch my head if these weren't brand new...really not used to a manufacturer warranty working like this either
"Wait...what?? You want me to pull parts off? A warrantied machine!? Can you say that again, I really don't wanna void a warranty you know" XD F didn't want you to even open the doors on a warranty machine, lol
I have never been able to duplicate the error. When I look at ufp and ufp_s trends in service mode for right before the machine was pulled the signals are the same; I don't see any differences between the two signals for the whole day (not just right then). Also, even though it was giving this alert I didn't see any error codes at all.
Either that's because it doesn't full on alarm (it's just a bottom message alert after all) but I figured it would still record that somehow...I probably just don't know what to look at for that though. I haven't had to look at the service mode trend logs to diagnose problems before so I may not be looking at the right things. I was comparing actual ufp and ufp_s signals but they looked identical...my glasses are an old script though XD

I can honestly say that I have never seen that message in our 15 years with these machines.
Unfortunately, you won't see anything in the trends because the machine doesn't start logging until the treatment is actually started, not during the self-test.
I highly doubt that it's the board since it's evidently intermittent since you can do a mock treatment.
As good as Adam, Rob, and Sergio are, I would try to talk to Brian and see what he says. We've only been able to stump him once or twice with problems.
Or if you can, I would suggest swapping the entire UF pump with a known good machine and see if the problem goes away or if it follows the pump.
Braun is great with warranty issues. Usually, they don't even want the bad part back. Whatever this ends up being, don't get rid of the bad parts. Since you have 5 with the same problem, it would probably good to talk to Rob about opening a PIR in which case they will want samples to be sent back to Germany.

I have had this on 2 of our newish machine both V9.18, First reseat all boards(Do this first especially if installer didnt do this) and check all the connectors. My Fixes are below but here is what machine is looking for at (LLS 20005 Since the start of the DFS pressure test more than 3 revolutions have been detected) Watch your UF_S at start of DFS Test(test 1.27) and see if it shows, IF no UF_S try swapping Acid or Bicarb connector and see if it Picks up UF_S if so hall sensor most likely, if still not reading harness or powerboard, Powerboard is easiest to swap. Harness and Basic Board would be last. 1st machine 1560 hours, was the power board effected all three pumps but only the supervisors reading were not showing. Just swap from a know good machine smallest board attached to basic board 2nd was wiring harness 125 hours, one of the Molex connector pins wasnt fully seated, Was in our acute program backup machine would randomly do this took forever to track down. |

It's possible the UF pump is stuck/jammed during the test.
Reasons for stuck/jammed UF pump could be citric acid not thoroughly being rinsed out during citric thermal; solution is to extend rinsing time in system configurations.
Or machine left in conductivity for a prolonged period of time.
the pump will usually free itself or it may need manual cleaning to unjam it

I saw this a few times on the version 8 machines a long time ago and it was the sensor the reads the stroke RPM. It might be the plugs as well. Unplug them and see if the plugs go all the way into the plug to make sure they make enough contact

Hi,
I have the same issue 6 month old machines, just out of warranty, V9E. I have 3 machines with "UF Pump Test will be repeated".
Bcjammerx, Have you found a resolve for this issue?
I cant find any information anywhere on this, Im waiting to hear back from Braun Tech Support.
Any information would be helpful.

pretty irritating a board is bad on a brand new machine but more so how bbraun does warranty repairs...if bbraun did like other companies and just sent a tech out this would have been fixed already...but I had to put this machine on the back burner and never got a chance to look at the sensor readout until last week. Ok end rant
When I did I saw the ufp reading one thing and ufp_s reading the same but fluctuating +2 over and back to what the ufp read...back and forth.
I put the machine in service mode and had it just sitting there...then I unplugged the connector (disconnecting the hall sensor) and ufp_s would do the same, fluctuate between 0 and 2 (as nothing was turning). So replacing the hall sensor wouldn't fix that so looks like the board will be the problem...this place has 2 backups (one with this one down) but all my other locations have regular failures (older machines) and no backups. in addition to other general biomed responsibilities I have this machine is staying on the back burner for now.
I wouldn't think this +2 reading would throw it off but it's the only thing off I can see, and it does it even with the hall sensor unplugged so board it must be *shrug

A quick note. The message “UF pump test will be repeated” means ANY piston pump can be having a problem. I have had this problem and it turned out that the BICP was the culprit. A loose wire in the connector.
Applies to any piston pump, not just the UF pump!!!
