Possible Causes
Loose connector at pressure sensor, Faulty pressure sensor electronics, Damaged wiring harness between sensor and control PCB, Control PCB input fault
How to Fix / Troubleshooting
Safety first: Unplug the washer before removing the top or front panels.
- Locate pressure sensor: Remove the top cover. The pressure sensor is typically mounted on the side frame or near the control panel with a small hose attached.
- Check connector: Gently unplug and replug the electrical connector to clean contacts. Inspect for corrosion or bent pins.
- Inspect wiring harness: Follow the harness from the sensor to the main control PCB. Look for pinched, cut, or burnt wires. Repair or replace damaged sections.
- Check hose connection: Ensure the small pressure hose is firmly attached and not cracked. Air leaks can cause erratic readings.
- Replace sensor if needed: If connections and hose are sound but E08 persists, replace the pressure sensor with a Primus-compatible part, transferring the hose and connector.
- Test cycle: Reassemble, restore power, and run a short wash to confirm the error is cleared.
