Fisher & Paykel offers no owner fix for E40, only a service booking, and warns against cutting power to a hot oven.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so E40 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
The freestanding cooker article lists E40, along with U400, as a power supply error.
A short entry from the manufacturer
Fisher & Paykel says little about E40 beyond the steps above. The code is in the support article on F, A, E and U codes for freestanding cookers, under the heading power supply error. Only one other code, U400, shares that heading.
What is missing
The article provides reset procedures for door lock errors, for the induction cookware message and for board or software errors. E40 is in none of those groups.
For “all other fault codes”, it gives one instruction: book a service repair.
It names no cause. A power supply error might originate outside the appliance or inside it, and the article does not say which.
Treat nothing here as a diagnosis.
Safe things to do
Copy the code exactly as displayed; the article’s tips want it ready at the time of booking.
Find out if anything else at home lost power. That tells you whether to mention the supply side.
Do not switch the power off while the oven is hot. The article’s first warning says to do so only when told, because an oven that is too hot may be damaged, along with the cabinets nearby.
Why a technician
The manufacturer gives owners no step for this code, and opening panels is neither safe nor needed.
