Wolf CT Induction Code E43: induction generator has failed

What E43 means

On earlier Wolf CT induction cooktops, such as the CT30 and CT36 sizes, E43 reports an induction generator failure. This differs from its neighbors: E44 and E45 describe generator burner sensors reading open, with E44 pointing to the RL burner. With E43, the generator itself is the concern, so the burners it powers will not heat. The display shows E43 and part of the cooktop may be dead.

Common causes of E43

Induction generator failing
Generator board or its connection damaged
Power disturbance that left the generator tripped

✓ One safe check you can try

1. Turn all burners off and let the cooktop cool. 2. Switch the breaker off for one minute, then on. 3. Try the dead burners once. 4. If E43 returns, leave the cooktop off; do not open it. 5. Call us so we can check the generator and parts availability.

! Why to stop there

A failed generator is an electrical problem we do not want to power up repeatedly.
Generators for some older CT models can be hard to source, so we confirm before quoting.
We give a written price first and a 30-day workmanship warranty after.

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.

E43E43 questions

How is E43 different from E44 and E45?

E43 is a generator failure. E44 and E45 are burner sensors reading open, with E44 pointing to the RL burner. Having someone home who can show us the problem makes the visit quicker.

Can E43 be a one-time glitch?

A power disturbance can cause one. A breaker reset may clear it, but if E43 returns, the generator needs a proper test. We record what we measured so you can see exactly why a part was recommended.

What will you tell me before repairing?

We explain what failed, whether parts are available for your model, and the written price before we begin. When a reset helps only for a while, that pattern is itself useful information for us.
