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. Wolf cooktop display What to do when E18 shows on the cooktop ### Kind of code Boards 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 to Touch 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 as Cooktop 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. ### Make Wolf The cooking half of Sub-Zero Group, selling cooktops and rangetops from its Wisconsin base. ### Source Wolf answer: CT electric cooktop, error code E18 Wolf CT series electric cooktops. ## Before you book, in this order.

Switch the breaker off for 30 seconds and back on. If it comes back, it needs a visit. ### Does E18 on a Wolf electric cooktop always mean a new power board? Usually, but a loose connector or a supply problem can mimic it. The technician checks those first before ordering the board. ### What should I do if an element stays on with E18 showing? Switch the cooktop off at the breaker and leave it off, then book a visit. An element that will not switch off is a safety matter. ### Is there any home troubleshooting for E18 on a Wolf CT electric cooktop? Wolf states that no further troubleshooting advice is available for E18 beyond cutting the power. The power board that switches the radiant elements has to be tested in person. --- **[Read on the site: Wolf CT electric cooktop showing E18 | CooktopRepair.center](https://cooktoprepair.center/error-codes/wolf-e18/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
