You will need to recalibrate the modules to match the actual motor block attached to it.
To recalibrate the module, please do the following:
1. Disconnect the pump
2. Plug module into power (with no pump connected or jack on the side)
3. Run it until the light goes Red (around 30 seconds)
4. Unplug module from power
5. Plug in the pump
6. Power up module
Let me know if the issues continue after recalibrating the module to the pump connected to it.
