Title: Pureflow conductivity issues
Post by: Adam_W on November 23, 2007, 09:54:49 AM
I made a batch of dialysate last night, and I woke up to an alarm from the Pureflow. I discovered that it had failed the conductivity test. I cleared the alarm, it did the test again, and failed again. I ended up losing the entire 60L batch. I've never had this happen before. Has anyone else experienced this? Does anyone know what might cause it to fail?

We had it happen once a few months ago - no problems since.

We had it once a couple of weeks ago. When we went to drain and unload there was about an inch deep that had leaked out under bag (then we got the red 53 tub leak) We assumed it was because of that.  Lost the whole 60 L like you did. Never happened since.

One thing to try: After you clear the alarm but before you retest try to manually mix the sak - assuming no leak. It is a bit tricky but you should be able to reach your hand through and slosh the sak a bit which may help get the batch through the test. This can happen on standard machines too and you have to shake up the bi-carb jug.

I had a conductivity failure yesterday morning - just as I was making the batch.  I tried shaking the bag, and repositioning it and restarted about three times and then just gave up.

Which leads to my question ( I know that the answer may be in the manual - but I'm lazy...) is there any way to not have to run the drain cycle three hours when you are giving up on making a batch?  This was especially annoying as the batch that was wasted never even started in the first place.

You can drain for as long or as short a period as you want...just depends on how heavy you want the sack to be when you remove. I've found that after 2 treatments (I use 26L per treatment, so there's only about 8L left), it only takes about 45 minutes to drain the sack almost completely (though the machine wants to go 3 hours.) Just hold stop until it asks you if you want to end draining...say yes and it does a short final flush and you are good to go.

Thanks!
