Possible Causes
Liquid or cleaner under touch glass, Damaged capacitive touch sensor, Cracked glass over control area, Shorted control PCB tracks
How to Fix / Troubleshooting
Safety: Turn off the cooktop and disconnect power before cleaning inside the control area.
- Surface cleaning: Wipe the control area with a soft, dry cloth. Remove any sticky residue or dried spills.
- Drying: If liquid has seeped under the glass, leave the cooktop powered off for 24 hours to dry. Use gentle airflow (not heat) under the unit if accessible.
- Inspect glass: Check for cracks or chips over the control icons. Cracked glass can cause false touches and must be replaced.
- Internal inspection: If comfortable, remove the glass top and inspect the touch PCB for corrosion or residue. Clean with isopropyl alcohol and a soft brush.
- Replace control panel: If a specific key area always appears pressed or E7 persists, replace the complete touch control assembly.
