replace the bicarbonate pump.
EOS- 4.0.0 CHECK CONCENTRATE PUMP CIRCUIT
a) IMPORTANT! Turn the machine off to prevent damage.
b) Referring to Figure 63
(i.e. Acid pump to P16, "CONC- P"; Bicarbonate pump to P17, "BIC-P").
c) Five possibilities: 1) Bad actuator board; 2) Bad sensor cable; 3) Bad actuator cable; 4) Bad distribution
board; 5) Bad motherboard.
1. Actuator Board (see
a) IMPORTANT! Turn the machine off and swap in a known good actuator board.
b) Place the machine into Dialysis program (remember to press the 'CONFIRM' key).
c) Allow one minute then call debug screen 0. Is the pump's symbol remaining white?
Yes Problem solved! The previous actuator board is bad.
No Continue with EOS- 4.0.0, step #2 (the previous actuator board is okay).
2. Sensor Cable (see
a) IMPORTANT! Turn the machine off and swap in a known good sensor cable (or check
sensor cable).
