Technical gurus,

After an RO interlock correction, seven of fourteen H machines (supposedly?) alarming "Low flow Error". However, after an hour, they correct themselves. Has anyone ever seen this? For the record, what are the first possible problems and corrective measures? Lastly, what part/parts would you suspect and have on hand for corrective measures?

Thank you for your in-put.

I had this experience. The morning guy running the machines for two hours without the RO running (direct feed).

I had 10 out of 40 machines had the same meesage/problem in the same morning. Of course, he didn't tell me he didn't turn on the RO.

I think it is too much air inside the hydrauic.

Jim,

Thank you for the prompt reply, the in-put sounds right on.

We frequently see this problem when folks don't turn the water on in the morning. The machine goes into a No Water Alarm for a minute or so, then it goes into a Flow Inlet Error, or a Low Flow Alarm, and the staff sees that and pulls the machine. Then they remember to turn the water on when they put the next machine on line. When you get to the machine to repair it, the first thing you see is the Flow Inlet or Low Flow error, not a No Water Alarm. If you put the machine into Rinse for about three minutes you will see massive amounts of air in bob and the Dialysate lines and pretty soon, after your Deair pump quits making that ugly grinding sound all of the alarms and problems will clear out.
