What to do if my Raven Water Pump shows Code 103?

If your Raven Water Pump displays Code 103, it may be due to a flow obstruction in the left intake valve or a faulty left pressure transducer. Perform a pump calibration test. If the pump does not calibrate properly, remove the left intake cartridge and perform pump maintenance to clear obstructions. If the pump calibrates properly, replace the left pressure transducer.
