Pump and motor troubleshooting
Is the motor LED illuminated on the control board?
Is the motor on?
If the LED is illuminated, but the pump is not running, turn the pump on manually.
If the motor will not turn on, verify that the fuse is OK, and make sure there is power to the motor.
If you are still not getting flow from the pump, verify that the solenoid valve and relief valve are working correctly.

testing the flow sensor
1. Turn ON the power.
2. Measure the VDC between TP2 and TP9.
TP9 is 67% scaled voltage from the flow sensor. Normal flow is 3.8 lpm (1.0 gpm), which will equal 0.67 VDC at
TP9.
