Yes BOTH ‘dots’ turn white for more than thirty (30) seconds again! If ABSOLUTELY SURE the
Dialysate Sampling Hardware Option has a blue ‘X’ in the No box the Functional Board
may be bad.
No BOTH dots do NOT turn white at the same time. See parts A AND B below:
A) If the flow error was originally occurring in Heat Disinfect return to it! If not leave the
machine in RINSE.
B) See procedure number CLEAN- 5.3.0 (page 204).
CLEAN- 5.3.0 VERR = 0 / ISOLATE TOTAL FLOW
a) Leaving the shunt door OPEN, ENSURE a “No Water” alarm NEVER occurs!
b) Watching for thirty (30) FULL seconds, does the external flow indicator’s ‘bob’ EVER rise about ½ way
up OR higher in the sight glass?
Yes ‘Bob’ moving! See procedure number CLEAN- 5.4.0 (page 204).
No ‘Bob’ NOT moving! See parts a through d below:
a) ENSURE no tubing restrictions at the Flow Pump AND the DiaSafe

b) ENSURE Flow Pump Pressure (gauge at Flow Pump) is PEAKING to between 34 and 37 psi.
c) ENSURE Loading Pressure (gauge in Rinse port) is peaking to between 22 and 27 psi.
d) Proceed to
page 607 to troubleshoot this restriction using procedure number
LEAKING- 4.0.0!
CLEAN- 5.4.0 ISOLATE FLOW ERROR
WITHOUT LOOKING AWAY, watch specifically for a “Flow Error” AND / OR a “Flow Inlet Error” for four (4)
minutes OR until if either one EVER occurs?
Yes “Flow Inlet Error” AND / OR “Flow Error” occurs! Proceed to page 205, procedure number
CLEAN- 6.0.0.
No Neither alarm occurs! See parts a THROUGH c below:
a)
Close the shunt door!
b) Assuming neither alarm EVER occurs, allow Remaining Prerinse Time to reach 0:00!
c) Watch until if a “Flow Recirc Error 1” occurs OR until if the program completes! TWO (2)
possible scenarios (next page):
