d) Call debug screen 0. If (and ONLY if) Flow Error = 1 constant see procedure number
e) Press and release the 'RESET' key then immediately press and hold it for three seconds. If the "Adjusting
TMP" message is present allow it to expire. Ignore temporary Flow Errors during reset!
f) If a TMP alarm occurs repeat the RESET sequence up to twice more. If (and ONLY if) the TMP alarm
returns after two reset attempts proceed to page 181, procedure number
g) Assuming all procedures were performed correctly the Troubleshooting Guide is unable to locate an
immediate problem. The Flow Error (assuming that you saw a Flow Error) is intermittent. The following
steps may help.
h) Turn Dialysate flow OFF (Dialysate Flow on/off LED blinks). Call debug screen 10. If ACFS
is NOT remaining between 4.0 and 5.5 the CFS transducer #10 may be intermittent bad
(see Figure 21, page 43).
i) Turn Dialysate flow ON (Dialysate Flow on/off LED off) and watch loading pressure for several minutes.
If the deaeration pump is stalling or if the float switch is intermittent bad loading pressure falls below the
minimum and/or a "Flow Inlet Error" and/or a "High Flow Error" message appears. ALSO continue to
keep an eye on ACFS (screen 10) if it drops to and REMAINS less than 2.0 for longer than two seconds
it may be intermittent bad.
j) NOTE this procedure and page number in case you need to return here.
k) From the Home screen, if TMP varies greater than +/- 60 mmHg in three minutes
tests will be performed: 1) IOS; 2) Balancing Chamber Valves #31 through #38. See
AUTOMATED VALVE LEAK TESTS
l) If a leak is not located, perform
DIAPHRAGM (page 238).

m) High Flow Error" AND Conductivity greater than 16.5 mS may be due to s stuck closed balancing
chamber valve. Procedure number
F- 4.0.0 CHECK VALVE #24 AND #43
IMPORTANT!
a) If not already done perform
b) Referring to the Figure (below), look CAREFULLY. Are valves #24
distribution board positions?
Yes See procedure number
IMPORTANT!
No
F- 4.1.0 VERIFY FLWOUT
ASSURING that valves #24 AND #43 are plugged in correctly:
IMPORTANT!
a) Turn the machine off then back on.
b) Return to Dialysis program (remember to press the 'CONFIRM' key).
c) ASSURE Dialysate flow in ON (Dialysate Flow on/off LED off).
