Induction cooktop displays E5 and shuts down during operation, often when multiple zones are used.

Safety first: Disconnect the hob from mains before any internal inspection.

• User-level steps: Reduce the number of zones used at maximum power simultaneously. Try operating at a slightly lower power level to see if E5 still appears.
• Ventilation check: Ensure adequate airflow under the hob. Overheating can trigger overcurrent protection.
• Technical inspection: A technician should inspect the power module for signs of overheating, check heat-sink mounting, and verify that thermal paste is intact on power devices.
• Module replacement: If internal current sensing or power devices are faulty, replace the affected power module.

Note: E5 is often a protective response; do not bypass or override it.
