Hello, I have a 2008T machine with Bibag that originally had a no chemical intake alarm. The acid pump has been changed. I am not getting the alarm at the moment but I get inconsistent conductivity. When I try to calibrate the acid pump, the liquid does not pull a consistent amount each stroke in the burette. When I try to calibrate the bicarb pump, it does not have a defined stroke. The liquid as you watch in the burette does not stroke, then stop, stroke then stop. Hard to explain. If swap the bicarb and acid pump on the distribution board does not follow the pumps. So far I have tried, Valve test passed. Sensor board, sensor cable functional board and bicarb board. actuator board, actuator cable. power logic board. Deaeration, flow and loading pressures good. Dearation and flow motors, pump heads all good.
Any ideas?

My first instinct is actuator board, wires. Then motherboard, distribution board. Sensor board is less likely. If you know it isn’t the pump then the issue is likely with inaccurate communication between pump and board, what’s in between.

Do you have any way of knowing if the machine had these pump issues before you started working on it? Could it be something that happened during the repair?
I have to agree with jaretac's reasoning. I would have first thought the actuator board or cable, but you replaced those. What's left between the actuator board and the pumps?

check your flow motor brushes and your d motor brushes

Run it through a rinse program and make sure you don't have any hidden pump errors or hear grinding from the pumps
