VE- 5.0.3 VALVE #35 UNPLUGGED AND VALVES DO NOT CYCLE
a) At the distribution board (Figure above), unplug Valve #38’s connector.
b) Watch the Balancing Chamber Valve ‘dots’ for forty-five (45) seconds. Do they begin to cycle between
white and blue?
Yes The Balancing Chamber Valves begin to cycle between white and blue! Valve #38 OR its blue
wire harness is bad.
No The Balancing Chamber Valves do not cycle after Valves #32, #33, #35, and #38 have all been
unplugged! See parts A and B below:

B) Turning the machine off first, swap in each component (see Component List below), one at
a time, returning to Dialysis Program in between, until VERR remains = 0 for ten (10)
minutes indicating the last component swapped in is the problem.
