What Does Error F9 Mean?

The Fisher & Paykel dishwasher F9 error indicates a malfunction in the drain pump, often due to an electrical fault detected by the control board. This can cause the dishwasher to stop mid-cycle, produce unusual noises, and fail to drain water. Common causes include abnormal power or current issues, loose wiring, or poor connections to key components.

Common Symptoms:

  • Dishwasher stops mid‑cycle with F9 displayed
  • Both drawers may lock and not reset via breaker
  • No normal operation until fault cleared

Possible Causes

  • Control board detects abnormal power/current on components (controller/power supply fault) (medium)
  • Loose/corroded wiring or poor connections to key components (medium)

How to Fix Error F9

DIY Fix Basic reset and visual inspection

  1. Turn off dishwasher and disconnect power at breaker or wall outlet
  2. Wait a few minutes and restore power to see if error clears
  3. Visually inspect visible wiring/connectors for moisture or corrosion
  4. Ensure water isn’t pooling in base (flood sensor not triggered concurrently)

Technician Only Detailed diagnostics and component testing

  1. Disconnect power and remove access panels
  2. Use multimeter to measure resistances of suspected circuits per service guidelines (power resistor, valves, sensors)
  3. Inspect control board and chassis harness for signs of burning or corrosion
  4. Test individual components in diagnostic mode per service manual recommendations
  5. Replace faulty wiring, connectors, or components as identified

Parts needed: multimeter, replacement connectors/wiring, control board (if confirmed faulty), associated components

🛑 When to Call a Pro:
  • If fault persists after reset and visual inspection
  • If you cannot safely access internal components
  • If diagnostic testing identifies control board failure
