E101
Bosch E101 on oven: temperature sensor malfunction
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
Your Bosch oven shows E101 because it detects that the temperature sensor is malfunctioning. Switch the oven off at the circuit breaker for five minutes and back on; if it was recently installed, ask the installer to check the power cord connection.
Safety first
Stop and check this first
- Do not open the terminal box or touch the range power cord wires: they carry mains voltage. Checking them is a job for a qualified installer or electrician with the power cut.
Safe checks you can perform
- Circuit breaker reset
- Power cord connection check
- Call Bosch service with the history
Leave these tasks to a qualified professional

What a technician must be able to justify
A technician is coming
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.
Temperature sensor measurement
What they doBosch service measures the temperature sensor and its wiring with an instrument, with the appliance de-energized, and compares it with the manufacturer specification.
They must show youthe measured value against the Bosch specification.
In writingthe measurement, the replaced part with its reference and the final heating test.
Electrical connection verification
What they doAn electrician or the technician checks the power cord connection and its color match with the appliance.
They must show youthe terminal box checked, or a photo of it.
In writingwhat was wrong, if anything, and what was corrected.
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.
Circuit breaker reset
- Who:
- you.
- How:
- switch the oven off at the circuit breaker, wait five minutes and switch it back on, as Bosch instructs.
- Result that matters:
- whether the oven starts and heats without e101.
- If it does not return:
- it was a temporary state; watch for repeats.
- If it returns:
- check whether the installation is recent and move on to the connection check.
- Evidence to keep:
- a photo of the code on the display and of the rating plate.

Power cord connection check
- Who:
- the installer or a qualified electrician, never you.
- How:
- if the range was recently installed or moved, ask them to check that the power cord wire colors match the appliance wires, as Bosch asks.
- Result that matters:
- the professional confirming the connection is correct or fixing it.
- If they find and fix a wrong connection:
- that was the cause if e101 does not return.
- If the connection was fine:
- rule this cause out and call Bosch service.
- Evidence to keep:
- the installer's report of what they checked and changed.
The mains connection is live: only a qualified installer or electrician, with the power cut, may open the terminal box.

Call Bosch service with the history
- Who:
- you.
- How:
- if the code persists, write down the model, the code and what was already checked before calling Bosch.
- Result that matters:
- the technician arriving knowing the connection and reset are already ruled out.
- If the oven also heats poorly:
- say so, it helps focus the sensor diagnosis.
- If the code shows only in certain modes:
- note which ones.
- Evidence to keep:
- the photos and the installer's report.

What it means
For the freestanding ranges Bosch documents on its US site, e101 means the temperature sensor on the appliance is malfunctioning. Among the steps, Bosch asks to check that the power cord connection is correct, with the cord wire colors matching the appliance wires, so a wrong connection can also trigger the warning. The code alone does not prove the probe is broken: rule out the electrical connection and a temporary electronics state first.
Warnings and stop conditions
- Higheditorial warning
Do not open the terminal box or touch the range power cord wires: they carry mains voltage. Checking them is a job for a qualified installer or electrician with the power cut.

Symptoms and causes
Probable causes · in order
- Incorrect power cord connectionPossible
More likely on a newly installed or moved range: Bosch asks you to check that the wire colors match those on the appliance.
Evidence: Bosch Freestanding Range Error Codes
- Temporary electronics statePossible
The code clears after cutting power for five minutes and the oven heats normally again.
Evidence: Bosch Freestanding Range Error Codes
- Faulty temperature sensorPossible
The code returns with a verified connection and after the reset; only Bosch service can confirm it by measuring the sensor.
