G1311B 1260 Quaternary Pump with built-in degasser issue

For the past couple of months the built-in degasser unit on my G1311B 1260 Quaternary Pump has been making a constant squeaking noise, even when the pump is not in operation. When the power to the pump is turned off, the noise is gone, but once the power is turned on, the constant squeaking noise appears again. Does the built-in degasser need to be replaced?
