Induction cooktop shows E6 and will not operate; may appear after a power surge or lightning storm.

Safety first: Switch off the cooktop at the breaker before any inspection.

• Step 1 – Power reset: Turn off the circuit breaker for 10–15 minutes to fully discharge internal capacitors. Restore power and check if the error clears.
• Step 2 – Check for moisture: If the error appeared after a spill or steam exposure, allow the cooktop to dry for several hours. Use gentle ventilation; do not use direct heat sources.
• Step 3 – Inspect wiring harnesses (technician): Remove the cooktop and open the housing. Check the ribbon cable and connectors between the touch control (user interface) board and the main power board. Reseat connectors and look for corrosion or burnt pins.
• Step 4 – Visual board inspection: Examine both boards for burnt components, cracked solder joints, or bulging capacitors. Any visible surge damage usually requires board replacement.
• Step 5 – Replace defective board: If communication lines and supply voltages are correct but E6 persists, replace the user interface board first (most common), then the power board if necessary.

Because E6 often indicates serious electronic failure, professional diagnosis with Balay service documentation is recommended.
