Wolf Legacy Induction Range Code 03: Sensor constantly activated

What 03 means

On pre-2018 Wolf induction ranges such as the IR304TE/S/TH and IR365PE/S/PH, code 03 means the control glass sensors report a continuous touch. The usual reason is liquid or cookware resting on the touch area, so the control thinks a key is being held down. You will see 03 in the display, and the cooktop may ignore taps or beep on its own until the glass is clear.

Common causes of 03

Spilled liquid or a wet cloth lying on the control glass
Cookware or a utensil resting on or touching the sensor area
A sensor zone that keeps reading touched even when the glass is dry and clear

✓ One safe check you can try

1. Turn every element off and remove all pans and utensils from the glass. 2. Wipe the control area with a dry, soft cloth, then let it air dry for a few minutes. 3. Turn the range breaker off, count to sixty, then restore power. 4. Touch one key to see whether 03 returns. 5. If 03 comes back on a clean, dry surface, stop and call us.

! Why to stop there

A sensor that stays on with a dry glass needs testing, because wiping will not cure it.
Pressing keys repeatedly on a confused control can start elements you did not intend.

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

What does 03 mean on my Wolf induction range?

It means the touch sensors detect a constant press. On the older IR ranges this is normally liquid or cookware on the control glass. Clearing and drying the area is the first thing to try.

Why did 03 appear while I was cooking?

A boil-over or a pan edge near the control area can wet the sensors. Take the pan off, wipe the glass dry, and wait a few minutes. If the message stays, the sensor itself may need attention.

Can I keep using the range with 03 showing?

We would not. A control that reads a key as held may react unpredictably. Clear the glass first, and if it persists, book a visit and we will quote before any work.
