What E18
actually means.
Wolf lists E18 on its CT electric cooktop as a power board failure. The power board switches the radiant elements, and E18 means it is no longer working as the control expects.

What to do when E18 shows on the cooktopKind of codeBoards and communication
The touch board and the power board under the glass lost track of each other, or one failed its own start-up check. A power dip, a ribbon or harness pulled loose when the top was fitted, or moisture from a boil-over is ruled out before a board is replaced, and a cooktop that keeps heating while this code shows is switched off at the breaker.
Usually leads toTouch control repair
Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting.
Shows up asCooktop Element Not Heating
A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil.

Before you book,
in this order.
Each step comes from Wolf's own guidance for E18 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Switch the breaker off for 30 seconds and back on.
Retest; if E18 shows again, book a visit, since Wolf gives no further home step.
If any element stays hot after being switched off, turn the breaker off and keep it off until the technician arrives.
What not to do
E18 is not a keypad message and does not point at one element. It concerns the board behind them.
