Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. Code 3 is an informational fault. Once the control area is cleared, the cooktop resumes normal operation. No safety hazard exists at any stage of the error.
Can I reset the code?
Yes. Code 3 clears automatically when the obstruction is removed, or with a breaker reset if liquid has penetrated behind the glass.
When to stop immediately?
Stop if you notice: Code 3 persists after clearing the control area and a breaker reset, Any liquid has penetrated behind the cooktop glass.
Symptoms You May Notice
Continuous tone sounds as soon as a burner is powered
A steady audible tone plays through the cooktop's speaker whenever any burner is turned on, and the tone stops only when the control area is cleared.
Touch controls respond slowly or not at all
The capacitive touch area below the obstruction cannot accept user input because its sensing surface is loaded by the liquid or metal above it.
Error code 3 appears on the display
The cooktop shows 3 on its indicator display to tell the user where the fault is rather than leaving them guessing about the tone.
Possible Causes
Water or liquid spilled across the touch control area
A boil-over or a wipe-down during cleaning has left liquid sitting on the glass over the control sensing strip.
DIY PossibleCookware placed across the control area
A pot or pan has been set down on the glass covering the touch controls, either by accident or because the cook surface is crowded.
DIY PossibleHeavy grease residue over the touch strip
Accumulated cooking residue on the glass in the control area is dense enough to confuse the capacitive sensing.
DIY PossibleSafe Checks You Can Do
-
1
Clear all items from the control area
Remove any cookware, utensils, or objects from the glass directly over the touch controls. Wipe the control area dry with a clean cloth.
Wolf CI cooktops are very sensitive to the touch zone being loaded — even a light utensil can trigger code 3.

2
Reset power at the breaker if the code persists
If clearing the area does not stop the tone, switch off the dedicated breaker for the cooktop for 30 seconds, then restore power.
Residual moisture under the glass can hold the error briefly even after the surface is dried.
When to Call a Professional
Contact a qualified technician if:
- Evidence of liquid intrusion behind the glass
