NW- 1.0.8 IN HEAT DISINFFECT “NO WATER” REOCCURS
a) Call debug screen 4. If debug does not appear press ‘Escape’ then call sceen 4.
b) When Valve #43 is closed*, PDIA (left column) NORMALLY cycles between 0.0
and to more than 0.1. When Valve #43 opens it stays more than 1.0 but
NORMALLY for no more than sixteen (16) seconds.
* In Heat Disinfect Valve #43 automatically cycles between closed and open.
c) WITHOUT LOOKING AWAY, watch PDIA for forty-five (45) seconds. If it remains more than 0.1
continue to watch for forty five (45) more seconds. Does it EVER cycle to 0.0?
Yes PDIA cycles to 0.0! See procedure number NW- 1.0.10 (
page 157).
No PDIA REMAINS ALWAYS more than 0.1! See parts a AND b below:
a) Per the Figure below, double clamp Valve #43’s OUTPUT tubing. NOTE!
Valve #43’s output tubing extends towards the front of the machine!
b) Watch PDIA again for forty five (45) seconds. Does it NOW cycle to 0.0?
Yes PDIA now cycles to 0.0! Remove the clamps. Possible bad component: 1) Bad
Actuator-Test Board OR; 2) Bad Valve #43.
No PDIA still DOES NOT cycle to 0.0! A) ENSURE Valve #43 is double clamped
properly; B) Return to Dialysis Program, allow eight (8) minutes, and then check
for TMP problems.
