Neff E101 fault codewhat it means and how to fix it
The temperature sensor has failed. The only BSH oven code with a named component behind it — and it comes from manuals for compact ovens they stopped selling a decade ago.
Take care
What E101 means
This code needs its scope stated before its meaning, because getting that wrong would mislead a lot of people. It comes from manuals for compact ovens with microwave built roughly between 2011 and 2014. The Neff and Siemens manuals carry the table and the definition; the Bosch sibling names E101, E104 and E106 and says only that the microwave still works. Current manuals for the same product family have dropped the table entirely. So BSH published a proper named oven code table and then withdrew it.
If your oven is a current model, this code is not documented for it and you should read the E0111 catch-all instead. For the ovens it does cover, the meaning is unusually specific and unusually useful: the temperature sensor has failed, and the remedy is to call the after-sales service.
There is one genuinely valuable detail attached. BSH note that microwave operation is possible on its own — so on a combination appliance, the failure of the oven’s temperature sensing does not take the microwave function with it. That is the difference between an appliance you cannot use and one you can use for half of what you bought it for while you arrange a repair.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| The oven temperature sensor has failed | BSH state this outright rather than listing possibilities, which is rare enough in this category to be worth noting. It is the whole of their published cause. | Common |
| A break in the sensor wiring or its connector | An open circuit anywhere between the probe and the board reads identically to a failed probe, which is why the diagnosis belongs to whoever opens the appliance. | Occasional |
What to try yourself
Check your model first. If it is not a compact oven with microwave from roughly 2011 to 2014, this table does not describe your appliance and the generic E0111 answer is the relevant one.
Try the microwave function on its own. BSH specifically note it still works with this code present, which may buy you time before the repair.
Book the after-sales service. BSH offer no owner remedy for this code at all, and a temperature sensor is not a part you fit from the front of the appliance.
Get a qualified appliance engineer to look at your Neff E101
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.
What it costs to fix
Typical repair cost
£110–£220
Time on site
10 minutes
An oven temperature sensor is typically £20 to £45 as a part, but reaching it on a compact combination oven is the bulk of the job. Expect most of the cost to be labour.

Common questions about Neff E101
Is E104 the same as E101?
BSH publish them in the same row with one shared meaning, so on the evidence they are treated as the same fault. They do not explain the difference between the two numbers, and we are not going to fill that in.
What about E106?
E106 appears only in the Bosch version of this manual, and Bosch name it without ever defining it. All they say is that the microwave can still be used. We have deliberately not assigned it a meaning, because none has been published.
Why does BSH not publish this table any more?
We do not know. The observable fact is that the current manuals for the successor models reverted to the generic row about D and E messages, so the named table exists only in documents for appliances that are no longer sold. It is the only place in the whole BSH oven corpus where a temperature sensor code is published at all.
