General software errors on the convection and microwave combi oven; F203 has a restart step, F603 does not clearly.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so F203 / F603 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
Both F203 and F603 are listed by Fisher & Paykel as a general software error on the convection and microwave combi oven.
A Fisher & Paykel convection and microwave combi oven that displays F203 or F603 is reporting what the manufacturer words as a “general software error”. The manufacturer’s general note says some faults can be rectified by resetting the oven.
Before touching the power
The oven has to be completely cool.
The cooling fan has to have stopped.
With both true, reset the power to the oven and see whether the fault is gone. A fault that is still displayed calls for booking a service visit.
The F203 instruction
The row for F203 says to switch the oven off at the power supply, leave it for one minute, then turn it back on.
F603 is less clear
The fault table uses merged instruction cells, and the one closest to F603 does not obviously describe a restart. No restart step is clearly shown for F603, so if that code appears, book service.
What the code leaves open
No failed part is named. The source does not call the oven dangerous or damaged, and it does not point at a user setting as the cause. Leave the control panel in one piece: a combi oven contains a microwave section along with the heating elements.
If the restart changes nothing, ring (310) 872-1939 about your Fisher & Paykel combi oven in Los Angeles. Tell us which code appeared and the model number. The oven service page describes the oven work we take on.
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.
