wrong direction of valves DFS, df flow disturbed membrane moving
v9 but not sure on software version if that matters
I found this post
dialysistechnical.freeforums.net/thread/72/df-flow-disturbed
but I've got the other alert
My issue is this, the machine only does the "wrong direction..." alert intermittently and when it does the staff say it only does it after first treatment is finished. I've not seen the alarm during mock treatment so going off what staff say (thankfully one followed our advice and took a pic of the two error alerts).
Staff also stated the machine takes longer than others to come up to conductivity...seemed to go normal for me but it also didn't give me the alarms which staff had pics of so maybe it was acting right while I was looking at it. They also say it always gives the "df flow disturbed..." error but I didn't see it in my mock treatment.
Something I did notice was gurgling from the acid port on the machine but it passed all it's tests and conductivity was in range. The spike was pulled out and put into a jug and the machine used the bicarb cartridge. This gurgling made me think the VZ valve was messing up but it wasn't spewing water out of them...I stuck my finger in the acid port and it muted the gurgling...I don't remember any of my machines doing that normally.
I'm pretty new to Dialogs...aaaaand I tend to overthink things...so I'm not sure what the troubleshooting steps are for these two errors, I could go into tech mode to test the valves but even if the valves click how do I know they're actually allowing flow...or is checking the valves the wrong direction to take?
