TWO (2) checks for an intermittent bad motor or Actuator Board:
CHECK #1: a) Using the handle end* of a screwdriver, push on BOTH the FLOW AND DEAERATION
MOTOR shafts, release, then push again.
* Avoids potentially slicing your finger
b) Can you make EITHER motor stop rotating and REMAIN stopped (Yes or No)?

No Neither motor stops! See CHECK #2.
CHECK #2: a) Call the Home screen.
b) Figure right, set [Dialysate Flow] to “OFF” and press ‘Enter’.
c) Call debug screen 1. ENSURE FLWP = 255 i.e. Flow is off!
d) The Deaeration Motor should be running, the Flow Motor should
be OFF! Check for FLOW MOTOR rotation again!
e) Refer to the TABLE below:
F- 2.5.2 FLOW MOTOR NOT RUNNING / DEAERATION MOTOR RUNNING

Flow Motor
Rotating?
Deaeration Motor
Rotating?
Your Response

Yes Does not matter
Flow Motor rotating! If FLWP is NOT = 255 you did not turn Flow
off! If FLWP = 255, TWO (2) possibilities: 1) Either the motors
are reverse connected at the distribution board OR 2) The
Actuator-Test Board
1
is bad!
