Fisher & Paykel Induction Cooktop Code E5: filter board needs replacing

What E5 means

On Fisher & Paykel CI304DTB4 and CI244DTB4 induction cooktops, E5 appears in the cook zone display together with the other error letters and numbers this series uses. The listed action for E5 is to change the filter board, the electronics that conditions the incoming power for the zones. Owners see the code on the affected cook zone, and that zone may refuse to heat until the board is replaced.

Common causes of E5

Filter board that has stopped working and needs replacement
Power conditioning problem on the board behind the glass
Damage to the board after a power surge or moisture

✓ One safe check you can try

1. Turn all cook zones off and let the glass cool. 2. Switch the cooktop off at its breaker for one minute, then restore power. 3. Try the zone again with a flat-bottomed magnetic pan. 4. If E5 returns, leave the breaker off and call us. Do not lift the glass or open the cooktop.

! Why to stop there

The filter board sits under the glass beside live induction electronics, so it is not an owner repair.
Swapping the wrong board wastes money; we confirm E5 on site first.
Our written price comes first, and the repair is backed by a 30-day workmanship warranty.

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.

E5E5 questions

What does E5 mean on my Fisher & Paykel induction cooktop?

E5 points to the filter board. The action listed for this code is to change that board, so a reset may clear it briefly, but the board itself usually needs replacing before the zone works normally.

Can I keep using the other zones?

The code is tied to the cook zone display, so other zones may still heat. We still suggest stopping use until we look, because the filter board conditions the power the cooktop draws.

Will you tell me the cost before replacing the board?

Yes. We confirm the code on site, give you a written price, and only then start work. The new board carries our 30-day workmanship warranty.
