Possible Causes
- Pressure sensor calibration drift

- Check ring valve seat worn allowing backflow
Troubleshooting Steps
- Step 1: Verify the pressure sensor reading against a reference
Sensor reads accurately - Step 2: Check the hydraulic proportional valve response
Valve responds promptly - Step 3: Inspect the check ring valve for wear
Ring seats properly without leakage
How to Reset
