Bosch cooktop error codes can help identify problems with heating, overheating, electrical supply, control panels and other appliance functions. Our Bosch cooktop error codes guide explains common messages found on Bosch electric cooktops, induction cooktops and gas cooktops and rangetops, helping you understand the likely cause before deciding what to do next.
If your Bosch cooktop is displaying an error such as dE, F2, F4, F5, F8, U400, E7010, E9000 or another fault message, use the Bosch cooktop fault finder below to locate the code and see the recommended checks.
Bosch Cooktop And Rangetop Error Codes
Bosch appliances can display different error messages depending on the type and model of cooktop. Electric and induction cooktops may report faults involving overheated electronics, cooking zones, supply voltage, touch controls or automatic time limitations. Gas cooktops and rangetops can also display electronic fault messages that may affect normal ignition or operation. Bosch’s current support information groups its error-code guidance into electric cooktops, induction cooktops, and gas cooktops and rangetops.
Always check the exact model number of your Bosch cooktop before ordering a replacement part or carrying out repairs. Error messages can vary between appliance models and generations.
Bosch Cooktop Error Code dE
The dE message can indicate that demonstration mode has been activated. When demo mode is active, the cooking zones may not heat as expected. A power reset and the model-specific procedure for leaving demonstration mode may resolve the problem. Bosch lists dE under both its electric and induction cooktop error-code guidance.
Bosch Cooktop Error Code F2
F2 can indicate that the electronics have overheated. The affected cooking zone may switch off until the electronics have cooled sufficiently. Allow the appliance to cool and then retest it. Bosch includes F2 among its overheating-related electric and induction cooktop errors.
Bosch Cooktop Error Code F4
F4 can indicate that the electronics have overheated and that all cooking zones have been switched off. Allow the cooktop to cool before attempting to use it again.
Bosch Cooktop Error Code F5
F5 can appear when hot cookware is too close to the control panel. The heat can cause the electronics to overheat or can result in a cooking zone being switched off. Moving the cookware away from the controls and allowing the panel to cool may clear the problem.
Bosch Cooktop Error Code F8
F8 can indicate that the automatic time limitation has been activated. This can happen when a cooking zone has operated continuously for an extended period without interaction. Touching a control and selecting the cooking zone again can allow normal operation to continue.
Bosch Cooktop Error Code U400
U400 can indicate that the incoming supply voltage is outside the appliance’s normal operating range. Electrical supply problems should be investigated by a suitably qualified electrician rather than by attempting to alter the appliance’s electrical connection yourself. Bosch identifies U400 as an incorrect-supply-voltage error.
Bosch Induction Cooktop Error Codes
Bosch induction cooktops can display additional messages relating to connectivity, supply voltage, overheating and control-panel conditions. Examples include E7010, E9000, E9010, E7015, E8207 and E8208. Bosch also provides guidance for situations where all indicators are flashing or the control panel is wet or covered.
Bosch Gas Cooktop & Rangetop Error Codes
Bosch gas cooktops and rangetops can also display electronic error messages. An E or F message may indicate an electronics fault, while F2, F4 or F5 can occur when the electronic system has overheated and automatic ignition is not operating correctly.
If a gas cooktop or rangetop continues to display an error after the recommended reset procedure, further diagnosis may be required.
Bosch Cooktop Troubleshooting
Before looking for a replacement part, check the simple causes first. A wet touch panel, an object covering the controls, hot cookware positioned too close to the control area, or an appliance that has become overheated can all cause error messages or prevent a cooktop from operating normally. Bosch’s troubleshooting guidance also recommends checking the power supply and control-panel conditions when a cooktop will not turn on or heat correctly.
For electrical supply faults, internal electronic faults, gas-related problems and repairs involving internal components, use a suitably qualified professional.
How to Find Your Bosch Cooktop Model Number
Your Bosch cooktop model number is important when identifying compatible spare parts and checking model-specific error information. The rating plate or product information should be checked before ordering a replacement component.
When contacting a parts supplier, having both the appliance model number and the displayed error code available can make it easier to identify the appropriate component.

Frequently Asked Questions
What does dE mean on a Bosch cooktop?
dE normally indicates that demonstration mode has been activated. The exact procedure for leaving demo mode depends on the Bosch cooktop model.
What does F2 mean on a Bosch induction cooktop?
F2 can indicate that the electronics have overheated. Allow the appliance to cool before testing the cooking zone again.
What does F8 mean on a Bosch cooktop?
F8 can indicate that the automatic time limitation has been triggered after a cooking zone has operated continuously for an extended period.
What does U400 mean on a Bosch cooktop?
U400 can indicate an incorrect supply voltage. Electrical supply problems should be checked by a suitably qualified electrician.
Why are all the indicators flashing on my Bosch cooktop?
Bosch states that a wet control panel or an object covering the controls can cause all indicators to flash. Dry the panel and remove anything covering the controls before retesting.
