E9011 means the connection at the cooktop does not match the diagram Bosch supplies, for example a swapped or missing conductor. It is an installation problem the cooktop can detect. Bosch cooktop display What to do when E9011 shows on the cooktop ### Kind of code Induction power and coils An induction zone could not drive its coil as the board planned: no pan was detected, the current ran too high or too low, or the power stage reported trouble. The pan base, the supply voltage and a clogged air intake are checked before the coil or the power board is replaced, and a top that trips its breaker is left switched off until then. ### 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 Tripping Breaker The circuit breaker for the cooktop trips as a burner or zone switches on, at one particular setting, or a few minutes into cooking. ### Make Bosch A German maker whose US site lists gas and induction cooktops for building into the counter. ### Source Bosch cooktop and rangetop error codes (US support) Listed with U400 on Bosch's induction cooktop codes. ## Before you book, in this order. Each step comes from Bosch's own guidance for E9011 on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Switch the breaker off. 02 Do not open the junction box and swap conductors yourself, even with the breaker off. 03 Have the connection redone to the circuit diagram by a qualified installer, or book a visit to trace it. ### Still there?

Switch the breaker off. If it comes back, it needs a visit. ### Why did E9011 appear after my Bosch cooktop was replaced? The new unit is checking its own hookup. A connection copied from the old cooktop may not match the new diagram. ### Is it safe to cook while E9011 is showing? No. Leave the breaker off until the wiring has been corrected. ### What does Bosch mean by a connection that does not match the circuit diagram for E9011? Bosch supplies a circuit diagram with the cooktop and asks that it be reconnected to match it. E9011 means the cooktop detected a hookup that differs, such as a swapped or missing conductor. The fix is at the junction box, not inside the cooktop. --- **[Read on the site: Bosch induction cooktop showing E9011 | CooktopRepair.center](https://cooktoprepair.center/error-codes/bosch-e9011/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
