F204 means the user interface of the combi oven is not responding; a cooled power reset comes first.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so F204 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F204 is listed by Fisher & Paykel as the user interface not responding on the convection and microwave combi oven.
When a Fisher & Paykel combi oven displays F204, the manufacturer’s table says the “UI” is not responding. UI is short for user interface: the display and the controls used to set the oven. In daily use that can look like buttons or a screen that do not react properly.
What the manufacturer asks, step by step
Do not touch the power until the oven has cooled completely.
Wait for the cooling fan to stop, then go to the power supply.
Turn the oven off and keep it off for one minute.
Turn it on and try the controls.
If F204 shows up again, the instruction is to book a service call.
Why start with a restart
A general note on the manufacturer’s page says some faults can be put right by resetting the oven, and F204 carries that reset instruction. Keep the power off for the full minute.
Cause and cleaning
Fisher & Paykel gives no cause for F204. Wiping the screen does no harm, though nothing suggests it helps, and cleaner sprayed into a control panel can cause damage.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
