Wolf CI Induction Cooktop Code 03: Continuous Sensor Activation

What 03 means

On Wolf CI induction cooktops from 2015 onward, such as the CI304T/S and CI365C/B, code 03 means continuous sensor activation. The control area is sensing a touch that never ends, and you hear a continuous tone. Water, a spill, or cookware resting on the touch controls is the usual reason. The cooktop may ignore your settings until the area is clear.

Common causes of 03

Water or spill on the control area
Cookware or utensil resting on the touch controls
Touch sensor seeing a stuck input

✓ One safe check you can try

1. Switch every zone off. 2. Remove pans, cloths, and utensils from the control area. 3. Wipe the glass dry with a soft cloth. 4. Wait a minute, then touch the controls again. 5. If code 03 returns on a clean, dry surface, call us.

! Why to stop there

A tone that keeps going on a dry glass points to the sensor itself.
Replacing glass or electronics is not an owner task.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

0303 questions

Why is my cooktop beeping nonstop?

Code 03 means the touch sensor thinks a control is pressed all the time. Water or a pan on the controls is the usual cause.

Can I clear it by wiping?

Often yes. Turn the zones off, remove anything on the controls, and dry the glass. The tone should stop. Spills and damp cloths are the usual reasons, so turn everything off before you wipe the glass.

When is it more than a spill?

If the code returns on a dry, clear surface, the sensor needs service. Call us and we will quote the price before starting. Our technician can test the sensor and the glass area, and we put the price in writing first.
