E21 has two resets: a one-minute power-off for induction cooktops and a cool-down plus 30 seconds for freestanding cookers.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so E21 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
E21 is a temperature or power issue in the full-surface induction cooktop article and an electronic board or software error in the freestanding cooker article.
Two articles, two resets
Which instructions apply depends on what you own. A stand-alone induction unit follows one article; a hob on a freestanding cooker follows the other.
Appliance
Label
Reset
Full-surface induction cooktop
Temperature or power issue (grouped with E2, E45, U400)
Disconnect the supply, count one minute, reconnect
Freestanding cooker
Board or software error
Allow fans to stop and the oven to cool right down, then disconnect for 30 seconds and reconnect
Cooktop notes
One tip from the article for this group: make sure there is good ventilation around the cooktop to prevent overheating.
Cooker notes
On cookers the article lists E21 among a long run of board and software codes, many of them F1xx, F2xx and F6xx numbers. Never skip the cooling stage: the article warns that removing power from an overly hot oven may harm it and the cabinets around it.
After you restart
No code? Carry on cooking. E21 again? Both articles finish the same way, by telling you to book a service repair. No owner-fixable cause is given, and electronics on mains power are no place for do-it-yourself work.
U400 is the last member of that temperature-or-power family.
