Wolf CT Electric Cooktop Code E67: triac connected in reverse

What E67 means

On Wolf CT electric cooktops (CTE and CTE-2), such as the CT30EU and CT36EU, E67 means the control found a reversed triac connection. A triac is the electronic switch for an element, and its wires are connected backward. This most often points to a wiring mistake after a repair. The display shows E67 and the affected element will not work correctly.

Common causes of E67

Triac connected in reverse after earlier work
Power module wiring disturbed
Power module needing replacement

✓ One safe check you can try

1. Turn all elements off and let the surface cool. 2. Turn the cooktop's circuit breaker off for 60 seconds, then reset it. 3. If the cooktop was serviced recently, tell us who and when. 4. Once E67 returns, stop and call us. Do not open it to look for loose wires.

! Why to stop there

Reversed wiring is not visible from outside and requires a careful look at each connection.
Running it that way can damage the module.

Our repair includes a 30-day workmanship warranty, confirmed in writing.

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.

E67E67 questions

Can E67 appear on a cooktop that was never repaired?

It is much more common after parts were replaced or reconnected. If no one has worked on yours, we inspect the power module for other causes.

Is correcting the wiring costly?

If wiring is the only cause, the fix is mostly labor, which we confirm on site. You then get the written price before we begin work.

Why not just try it again?

If the connection is truly reversed, repeated tries can damage the power module. We suggest leaving the cooktop off until we check it and correct the wiring.
