Fisher & Paykel Induction Cooktop Code E7: unknown error in the cook zone

What E7 means

On Fisher & Paykel CI244DTB4 and CI304DTB4 induction cooktops, E7 is listed in the cook zone table as an unknown error. In plain words, the cooktop has detected a condition in that zone that it cannot place under one of its specific codes. Owners see E7 in the zone display, and the zone may shut off or refuse to start until the cooktop is reset.

Common causes of E7

A one-time glitch in the zone electronics
Cookware or a spill that confused the zone sensing
A control or power module that needs a technician's test

✓ One safe check you can try

1. Turn all zones off and remove the pan. 2. Wipe away spills and dry the glass fully. 3. Switch the cooktop off at its breaker for one minute, then turn it back on. 4. Try a flat, magnetic pan on that zone. If E7 returns, stop using the zone and call us.

! Why to stop there

An unknown error cannot be solved by guessing at parts, so we test the zone to find the real cause.
Lifting the glass exposes live induction electronics.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E7E7 questions

Why does E7 say the error is unknown?

The cook zone table lists it that way, meaning the cooktop reports a problem it does not name more precisely. We read the zone on site to learn which module is actually responsible.

Is it safe to use other zones with E7 showing?

The code belongs to one zone. Use another only if it heats normally and stays steady. If the display keeps flashing codes, switch the cooktop off and call us before cooking again.

Can resetting the breaker fix it?

Sometimes a reset clears a passing glitch. If E7 returns after the reset, a hardware cause is likely and a technician should look at the zone instead of repeating resets.
