Possible Causes

Incorrect pressure sensor calibration, failed control board, wiring issue to sensor, software fault

Safety first: Unplug the washer before servicing.

Step-by-step:

Run calibration: Some models allow a water level calibration or diagnostic cycle (see tech sheet). Run this procedure.
Inspect pressure system: Verify the pressure hose and sensor are intact and properly connected.
Replace sensor or control: If calibration fails and hardware is good, replace the pressure sensor. If F75 persists, the main control may need replacement.
