Error code
Wolf induction cooktop error code E22
Wolf error code E22: the control panel is reporting a key or a sensing pad that is not behaving, 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 E22, 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 CI induction cooktop, Counter modules.

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.
-
Water reads as a hundred fingers Cooktop controls locked or acting alone
A touch surface that will not respond, or that changes settings by itself. On a glass cooktop the commonest cause is on top of the panel rather than under it, and it costs nothing to fix.
- A panel that ignores every press
- Settings changing by themselves
- A lock symbol nobody set
On the same generation
What else belongs to the CI 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.

About Wolf induction cooktop error code E22
What this one means
The control panel is reporting a key or a sensing pad that is not behaving, 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 key held down by something resting on the panel
- A capacitive pad reading a wet cloth as a finger
- The touch board itself, once the panel is dry and clear
- Pad error
- Stuck key error
- Config data in EEPROM corrupted; defaults used after micro reset
What to try yourself
- Note whether one zone is affected or all of them — each has its own generator
- Wipe the panel dry and take everything off it, including a towel over the handle
- Switch the breaker off for thirty seconds so the panel recalibrates on power-up
Then what
Capacitive panels calibrate to what they can see when they wake, which is why a cloth left on one at power-up produces an error that a reset clears. If it survives a clean, dry restart, it is the board.
