! Empty = 1/Bc Valves Not Cycling; Verr = 0/Bc Valves Not Cycling - Fresenius Medical Care 2008T Troubleshooting Manual

Yes ! EMPTY = 1: See procedure number
No ! EMPTY = 0: Either the arterial (red) dialyzer line IS NOT connected to the shunt properly OR
FOUR (4) possible bad components: 1) Actuator-Test Board
3) Arterial dialyzer line shunt door switch OR; 4) Motherboard

a) To ENSURE the shunt door is OPEN, CVRCLS (2
b) Watch DIALVLO (2
TWO (2) possible scenarios:
1)
IF (and ONLY if) DIAVLO REMAINS ALWAYS = 0! See procedure number
2) IF DIALVLO cycles between 0 and 1 (possibly rapidly) OR is remaining = 1! Valve #24 may be
in a malfunctioning electrical state! Proceed to
F- 2.4.0 VERR = 0 / BC VALVES NOT CYCLING
Call debug screen 1. Watch FLWP (upper right), for thirty (30) seconds! TWO (2)
possible scenarios:
1) IF (and ONLY if) FLWP REMAINS LESS THAN 255: See procedure number
2) IF FLWP is ALWAYS = 255! The machine may NOT be going in Dialysis Program! Perform parts a
THROUGH c below:
Turn the machine OFF!
a)
b) Turn the machine on and return to Dialysis Program ("Select Program" → 'Dialysis' → 'Enter')!
c) Call debug screen 1. ENSURING a "No Water" NEVER occurs watch FLWP for one (1) FULL
minute! TWO (2) possible scenarios:
1) IF (and ONLY if) FLWP IS NOT REMAINING = 255! See procedure number
(page 40).
2) IF FLWP is REMAINING ALWAYS = 255 (i.e. NEVER less than 255): With the machine off,
swap in the following components (Component List below) one at a time then, in between,
repeat parts b and c to test each one in between until FLWP does NOT REMAIN 255.
