E9000
Bosch E9000 on induction cooktop: supply voltage out of range
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
Your Bosch induction cooktop shows E9000 (or E9010) because the supply voltage is incorrect and outside the normal operating range. Do not keep trying: contact your electrical utility provider or Bosch service to have the supply checked.
Safety first
Stop and check this first
- Do not open the cooktop terminal box or measure the voltage yourself: it is mains voltage and the cooktop may be on a high power circuit. That is a job for a qualified electrician.
Safe checks you can perform
- Read the full code
- Behavior of the rest of the home
- Voltage measurement at the cooktop
Leave these tasks to a qualified professional
- Do not attempt this professional task: Supply voltage measurement
- Do not attempt this professional task: Cooktop diagnosis with correct voltage
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Supply voltage measurement
What they doAn electrician measures the voltage on the cooktop circuit with an instrument and checks its protection and connection.
They must show youthe measured value against the rating plate range.
In writingthe measurement, where it was taken and what was corrected.
Cooktop diagnosis with correct voltage
What they doBosch service checks the cooktop electronics once the supply is verified.
They must show youthe warning with correct voltage.
In writingthe check, the replaced part with its reference and the final test.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Read the full code
- Who:
- you.
- How:
- if you only see an E, press and hold the touch key of the zone where it shows to read the full fault code, as Bosch explains.
- Result that matters:
- confirming it is E9000 or E9010 and not another code.
- If it is E9000 or E9010:
- continue with the supply voltage steps.
- If it is another code:
- look it up in your model's manual; this page does not apply.
- Evidence to keep:
- a photo of the full code.

Behavior of the rest of the home
- Who:
- you, observing only.
- How:
- notice whether other appliances or lights fail, flicker or switch off at the same time as the cooktop.
- Result that matters:
- telling whether the problem is the supply or only the cooktop.
- If other appliances fail too:
- it points to supply voltage; contact the utility provider, as Bosch instructs.
- If only the cooktop fails:
- an electrician or Bosch service should check its connection.
- Evidence to keep:
- a note of date, time and which other appliances failed.

Voltage measurement at the cooktop
- Who:
- a qualified electrician or the utility, never you.
- How:
- ask them to measure the supply voltage on the cooktop circuit and compare it with the rating plate requirement.
- Result that matters:
- knowing whether the voltage is within the manufacturer range.
- If it is out of range:
- the problem is the supply or wiring, not the cooktop.
- If it is correct and the warning persists:
- call Bosch service with the measurement.
- Evidence to keep:
- the measured value and the electrician's report.
Measuring mains voltage requires instruments and training: only a qualified electrician or the utility.

What it means
On its induction cooktops, Bosch states that E9000 and E9010 mean the supply voltage is incorrect and outside the normal operating range. The cooktop control monitors the voltage coming from the household supply, so the warning can come from the utility network, the home wiring or how the cooktop is connected. The code does not prove the cooktop is faulty: the first step is to measure the supply, which only an electrician or the utility can do.
Warnings and stop conditions
- Mediumeditorial warning
Do not open the cooktop terminal box or measure the voltage yourself: it is mains voltage and the cooktop may be on a high power circuit. That is a job for a qualified electrician.

Symptoms and causes
Probable causes · in order
- Utility supply voltage out of rangePossible
Other appliances also see cuts or dips, or the warning matches problems in the area; Bosch refers you to the utility provider.
Evidence: Bosch Induction Cooktop Error Codes
- Incorrect installation or connection of the cooktopPossible
The warning appears from installation day or after building work; an electrician must check the connection and voltage at the cooktop.
Evidence: Bosch Induction Cooktop Error Codes
- Cooktop faultLess common
The measured voltage is correct and the warning persists; then it is a job for Bosch service.
