I have a F9 fault on top drawer of my Fisher and Paykel double drawer dishwasher. I have turned power on and off still there

It may be a bad power source. Our F9 happened during generator backup power and cleared once main power was restored.

F9 is a power supply or main control board fault. To eliminate power supply problem then every electrical part on drawer will need to be tested & inspected i.e. wiring, heater plate, motor, lid actuators etc. If all electrical side checks out ok then replace the main board. Big job needing proper test equipment.
