Answer to continue safely
Is it safe to keep using?
Yes. E3 is a safety feature, not a malfunction in most cases. The cooktop is safe to use — simply switch to induction-compatible cookware of the appropriate size.
Can I reset the code?
Yes. E3 clears automatically when compatible cookware is placed on the zone. No manual reset is needed — the zone will activate normally once a suitable pan is detected.
When to stop immediately?
Stop if you notice: Stop and call a technician if E3 appears on every zone with confirmed-compatible pans of the correct size., Stop using the zone if E3 is accompanied by an unusual buzzing or clicking sound from beneath the glass..
Symptoms You May Notice
Cooking zone does not heat and shows E3
The induction zone activates its detection cycle, fails to find a compatible pan, and displays E3 without generating any heat — the glass surface remains cool to the touch.
E3 appears immediately when a zone is turned on
Within 1–2 seconds of activating a zone, E3 is displayed because the coil detection circuit does not sense the magnetic response expected from an induction-compatible pan.
Zone shuts off automatically after displaying E3
The cooktop automatically cancels the zone after a brief pan detection timeout when no compatible cookware is confirmed, as a safety and energy-saving feature.
Clothes remain damp after a full cycle
Laundry comes out still wet or takes multiple cycles to dry because restricted airflow prevents proper moisture evaporation and exhaust.
Possible Causes
Non-induction-compatible cookware
The pan placed on the zone is made of aluminum, copper, glass, ceramic, or non-magnetic stainless steel — materials that do not respond to the induction coil's magnetic field.
DIY PossiblePan too small for the induction zone
The pan's base diameter is smaller than the minimum required for the zone (usually marked on the glass), preventing adequate magnetic coupling for the detection circuit to register the pan.
DIY PossibleFaulty induction coil or zone detection circuit
The induction coil or its associated electronics have failed and can no longer generate or detect the magnetic response needed for pan detection, even with confirmed-compatible cookware.
Requires ProfessionalSafe Checks You Can Do
-
1
Test cookware compatibility with a magnet
Hold a refrigerator magnet to the bottom of the pan you are trying to use. If the magnet sticks firmly, the pan is induction-compatible. If it does not stick or sticks very weakly, the pan will not work on an induction cooktop.
-
2
Try a different confirmed-compatible pan
Place a cast-iron skillet or a pan labeled 'induction compatible' on the zone and attempt to activate it. If the zone heats normally, your original cookware was not compatible.
-
3
Check the pan size against the zone markings
Look at the zone's size indicator etched on the glass cooktop surface. The base of your pan must cover at least the minimum diameter of the zone. Try a larger pan if E3 persists with compatible cookware.
When to Call a Professional
Contact a qualified technician if:
- E3 appears on all zones simultaneously with confirmed-compatible cookware.
- One specific zone shows E3 while other zones work normally with the same pan.
- Induction coil or zone control board replacement is required.
