F443 on the combi oven is an inverter error; the maker lists a service call.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so F443 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
F443 is listed on the combi oven as an inverter error and the manufacturer says to book a service call.
The manufacturer’s entry for F443 uses one technical word: inverter. In a combi oven with a microwave function, an inverter is the power electronics that run the microwave source. The source does not say this itself, so read it as a general description of inverters in microwave equipment and not as a diagnosis of your oven.
Place in the table
F443 ends the run that starts at F440. The three codes before it are the generator drain, water level sensor and generator pump errors, and the run shares a single direction: a service call.
What to do
Stay away from microwave and combination functions while F443 is showing.
Leave the outer casing on. A combi oven holds microwave and mains-powered parts.
Note which function was running when the code came up.
Reset?
No. The Fisher & Paykel page has a general reset note for faults that clear on restart, but F443 is not given a restart instruction.
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.
