Hi my name is***** will be glad to help. There are a few things that will cause this to check. Check inside the filter for fine metal/debris that would flag a pump, drive motor, or component failure occurring and check for excessive case drain pressure on the faulty drive motor side indicating a failed drive motor with excessive internal leakage. Also check the control valve for proper function and inspect the relief valve cartridge for damage and debris as well. Let me know
