Wolf CI and CE Cooktop Code 22 Pad Error: Stuck Key on the Controls

What 22 means

Wolf cooktops from 2015 show code 22 as a pad error, also called a stuck key. On CI induction models such as the CI304T/S, it often means a pan or utensil is on a control pad. On CE electric models such as the CE304C/B and CE365T/S, it is the same stuck-key condition. The cooktop may stop responding until the pad is clear.

Common causes of 22

Pan or utensil sitting on a control pad
Water or spill on the touch area
Pad itself stuck or damaged

✓ One safe check you can try

1. Make sure no zone is on. 2. Lift off any pan, towel, or utensil near the controls. 3. Dry the glass with a soft cloth. 4. Wait a minute, then touch a control. 5. If code 22 stays on a clean, dry glass after a minute, call us so we can quote the repair.

! Why to stop there

A pad that stays stuck on a clear surface needs inspection.
The control sits under the glass, so owners cannot reach it.

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.

2222 questions

Does code 22 mean the same on CI and CE?

Yes, both show a pad error or stuck key. On CI induction models a pan on the pad is a common cause. Both cooktop types show the same message, so the meaning does not change between induction and electric models.

What is a stuck key?

The control senses a pad as pressed when it is not. That can be water, an object, or a pad problem. It is a pad that the control believes is pressed, which can come from cookware, moisture, or the pad itself.

How do I know it needs service?

If a dry, clear glass still shows code 22 after a minute, call us and we will quote the repair before we begin. A technician checks the pad and the control under the glass, and you receive the price before work begins.
