SOURCE: error code. Fisher and Paykel Dishwasher

well since you asked on the 5th July, and no reply, doesnt look like you may get one. I thought thats what this site was about??

SOURCE: Error code F32 for fisher

Got the same error here, called Fisher Paykel and the said it's an error related to the water line. They recommended running 3 L of water and see if code disappeared. If not, call service, they gave me a local company. Error code has disappeared, for now.

The F24 error show that the sensor in the ice maker is out of normal ranges. The usual fix is to replace the sensor in the ice maker.  Also worth checking it to see is the water to the ice maker has frozen up in the value (switch the fridge off for a day). If the error still exists after that you will need to replace the ice maker sensor. You have a 2 year warranty on these parts so the fix should be free.

Disconnect the Fridge for 5 mins. After that, should be ok.

press the select button ( the button that you choose the temperature on the fridge and freezer) and check that the fan on both fridge and freezer are working.
