Quick Answer
Error code F8 on your Fisher & Paykel Dishwashers means: Motor Controller Fault. This is usually fixable — see the step-by-step guide below.
Affected Models
Applies to all models
DD24DCTX9NDD24DHTX9NDD24SAX9NDD24SI9NDD60DCHX9DD60SDFHX9
Likely Causes
  1. Motor controller/driver board has a failed power component (MOSFET or IGBT)
  2. Motor is drawing excessive current due to a partial winding short, overloading the controller
  3. Power supply voltage to the motor controller is outside acceptable range
  4. Controller board has suffered heat damage from inadequate ventilation around the unit
How to Fix It
1
Disconnect power and access the motor controller board inside the DishDrawer housing
2
Inspect the controller board for visible burn marks, overheated components, or swollen capacitors
3
Test the wash motor windings for resistance to rule out a motor short as the root cause of the controller failure
4
Check the power supply voltage at the controller board connector (should match the expected line voltage for your region)
5
Replace the motor controller board; if a new controller also fails, the wash motor may be causing the damage and should be replaced
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
