Error code
Wolf induction cooktop error code E41
Wolf error code E41: a switching device is passing current when the control has told it to stop, on an induction cooktop, where the generator under each zone is a power supply in its own right and reports for itself. What the code covers, what to check first, and what it does not tell you — on cooktops & rangetops.

What we can confirm
Code E41, from the manufacturer's own documentation
A code is only meaningful together with the generation showing it — the same two digits mean different things across generations, and that is the commonest reason a code looked up online leads somewhere wrong. This one is recorded on CT induction cooktop.

What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
One zone or all of them Cooktop not heating
An electric or induction cooktop with power and no heat. One zone out and the rest fine is a contained repair; all of them out is usually the supply or the control rather than the cooking surface.
- One zone cold, the rest working
- Every zone dead with the panel alive
- A code naming an element or a generator
On the same generation
What else belongs to the CT induction cooktop
A code belongs to a generation rather than to one cabinet. These are the other codes yours can show, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this generation can display
Ambient temperature too high
Generator 3 communication error
Either RTD temperature above specified limit SM15TF/S: RTD exceeds
Read line failure
Generator 2 heatsink temperature too high
Generator 3 heatsink temperature too high
Generator, burner sensor shorted

About Wolf induction cooktop error code E41
What this one means
A switching device is passing current when the control has told it to stop, on an induction cooktop, where the generator under each zone is a power supply in its own right and reports for itself. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- A relay welded closed by years of switching a heavy load
- A triac that has failed short
- The element circuit that relay or triac feeds
- Generator burner sensor shorted
Worth doing before you call
- Note whether one zone is affected or all of them — each has its own generator
- Switch the appliance off at the breaker if it is heating with nothing selected
Then what
A stuck relay is the one error in this archive that can heat with nothing asked of it, so it is a breaker-off condition rather than a wait-and-see one. The board carrying it is a replacement part.
This code is published for cooktops & rangetops. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
