The range reports an improper connection. Bosch's check is made against the circuit diagram by an installer or electrician.
Model compatibility: Bosch reuses codes across series and model years, so E9011 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E9011 means the appliance is not connected properly.
This is not a cooking-zone or oven fault. On Bosch’s slide-in range page, E9011 sits in the induction section and is described in plain words: the appliance is not connected properly. It points at how the range was wired to the house.
Bosch’s check
Disconnect power to the range.
Check the wiring against the circuit diagram.
That diagram is the range’s wiring drawing, and it shows where each supply wire belongs on the terminals.
Installer or electrician only
To check the hookup, someone has to work on the electrical connection of the range. Owners should leave it to the person who installed the range, or to an electrician. If the range has only just been delivered or moved, start there, and ask for the wiring to be laid against the diagram.
Two Bosch pages, two wordings
Bosch’s cooktop page handles the number differently: E9011 is grouped with U400 there, which can also signal an incorrect line voltage. The slide-in range page mentions only the connection. When the hookup is correct but E9011 stays, a look at the supply voltage is a sensible addition. Tell Bosch support precisely what was checked.
Once the connection has been compared with the diagram and E9011 is still showing, reach us on (310) 879-1577. Have the installation date ready, and the oven repair page lists what we do.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
