From the symptom it’s not obvious to me what’s the cause. This has nothing to do with I2C because OSPi does not use I2C for controller valves. It uses a shift register (74HC595). Some basic things you can check is the VIN-GND voltage (these pins are available at the top-right corner of the PCB). It should be about 5V when it’s powered.
