F- 7.0.0 Isolate Possible Restrictions; F- 7.0.1 Loading Pressure Okay (1) - Fresenius Medical Care 2008K2 Troubleshooting Manual

F- 7.0.0 ISOLATE POSSIBLE RESTRICTIONS

a) ENSURE Dialysate Flow is ON (Dialysate Flow on/off lamp NOT blinking)!
b) Recheck Loading Pressure (Rinse port gauge). It may not cycle but MUST reach a PEAK between 23
and 27 psi?
Yes Between 23 and 27 psi! See procedure number
No Less than 23 OR more than 27 psi! Return to

F- 7.0.1 LOADING PRESSURE OKAY (1)

A) Call debug screen 0. Watch Flow Error for one (1) minute. TWO (2) possible scenarios:
1) IF Flow Error is ALWAYS = 1 (i.e. NEVER = 0): See procedure number
2) IF Flow Error = 0 OR cycles between 1 and 0: See part B.
B) ENSURING the machine has been in Dialysis Program at least five (5) minutes. Call the Home screen.
Is [Conductivity] = 17.0 mS?
Yes [Conductivity] = 17.0 mS! See procedure number
No [Conductivity] is less than 17 mS! Possibly even within range sometimes but then drifts
high. See part C
C) As bicarb precipitate may be partially plugging hydraulic pathways perform (2) two subsequent Acid
Cleans using vinegar or citric acid.
D) After the last Rinse cycle, return to Dialysis Program ("Select Program" → 'Dialysis' → 'CONFIRM')!
E) Allow [Conductivity] to increase to more than 13.0 BEFORE continuing!
F) Set [Dialysate Flow] to 800 ml/min and press 'CONFIRM'.
G) Call debug screen 0.
H) WITHOUT LOOKING AWAY, watch Flow Error for up to FIVE (5) minutes OR until it EVER = 1, even if
just once! TWO (2) possible scenarios:
1) IF (and ONLY if) Flow Error EVER = 1! See procedure number
2) IF Flow Error ALWAYS = 0! A flow error is not presenting at this time! Possibly the Acid Clean
fixed the problem!
