E01 on a Wolf CT electric cooktop means the ambient temperature at the power module is at or above its limit. Wolf says the code clears once the temperature falls back below that limit, which its thermistors see as under about 85°F. Wolf cooktop display What to do when E01 shows on the cooktop ### Kind of code Temperature and overheat sensors A sensor under the glass or on a board reported a reading the control rejected, or heat climbing past the safe limit — often after an empty pan was left on a zone. The zone is allowed to cool and a loose sensor plug is ruled out before the sensor, the coil assembly or the board is blamed. A top that keeps getting hotter is switched off at the breaker first. ### Usually leads to Induction board and coil repair Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls. ### 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 E01 Wolf CT series electric cooktops. The CT induction cooktop uses E1 for a similar condition. ## Before you book, in this order. Each step comes from Wolf's own guidance for E01 on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Turn the elements off and let the cooktop cool. 02 Switch the breaker off for 30 seconds, restore it and retest. 03 Book a visit if E01 keeps coming back during normal cooking. ### Still there? It usually turns into [induction board and coil repair](https://cooktoprepair.center/services/induction-board-and-coil-repair/). Book with the code and the model number. ### What not to do E01 does not mean a radiant element is broken. It is the temperature around the power module. ## What you may notice with it.

Turn the elements off and let the cooktop cool. If it comes back, it needs a visit. ### Why does my Wolf electric cooktop show E01 on a hot day? The power module watches the temperature of the air around it, and a hot kitchen or oven below can push it over the limit. Once it cools, the cooktop should work again. ### Is E01 on a Wolf electric cooktop dangerous? It is a protective stop, not a hazard in itself. Repeated E01s during ordinary cooking suggest trapped heat or a sensor problem worth a visit. ### At what temperature does E01 clear on a Wolf CT electric cooktop? Wolf says normal operation should resume once the thermistors read under about 85°F (29°C). Until the air around the power module cools to that point, the cooktop keeps showing E01. --- **[Read on the site: Wolf CT electric cooktop showing E01 | CooktopRepair.center](https://cooktoprepair.center/error-codes/wolf-e01/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
