What Does Error F12 Mean?

The Fisher & Paykel washing machine error F12 signifies an overfill fault, where water level exceeds the flood level, causing the machine to struggle with drainage. Symptoms include the display of F12 on the panel, excessive filling, and repeated attempts to pump out water. This issue may arise from a malfunctioning pressure sensor or water level sensing system.

Common Symptoms:

  • Washer displays F12 on control panel
  • Washer may fill excessively or stop mid‑cycle
  • Machine attempts to pump water out repeatedly

Possible Causes

  • Excess water detected (overfill condition) (medium)
  • Potential pressure sensor / water level sensing issue (medium)

How to Fix Error F12

DIY Fix Initial user checks for F12 overfill fault

  1. Turn off the washer and interrupt the wash cycle.
  2. Verify that the washer has not physically overfilled and there is no water leaking outside the machine.
  3. Check water supply hoses to confirm they’re connected correctly and faucets are fully on without leaks.
  4. If safe, check the pressure tube (if accessible) is properly connected and not kinked or blocked.

Technician Only Technician diagnostics and repair for overfill condition

  1. Measure and test the water level pressure sensor and hose for blockages or leaks.
  2. Inspect and test water inlet valves to ensure they shut off correctly and don’t allow continuous water flow.
  3. Check drain pump operation and verify pump removes excess water at correct rate.
  4. Test wiring and harnesses for the pressure sensor and water level circuits; repair or replace faulty components.
  5. If sensor or valves are confirmed functional but error persists, evaluate the main control module logic relating to water level detection.

Parts needed: pressure sensor, pressure hose/tube, water inlet valve(s), drain pump, wiring harness, control board

🛑 When to Call a Pro:
  • If water continues to overfill despite shutting off the machine
  • If internal component testing is needed beyond basic checks
  • If electrical or pressure sensor components appear faulty
