Induction cooktop shows F19 and shuts down when higher power levels are selected.

Safety: Disconnect mains power. High-energy components are present; only trained personnel should service power electronics.

• Check for burning smell: Remove the bottom cover and smell near the power modules. A burnt odor or visible damage indicates a failed module.
• Inspect wiring: Verify that all internal wiring between terminal block and modules is routed and connected as per the wiring diagram. Look for pinched or shorted wires.
• Module replacement: If there is visible damage or F19 recurs immediately at moderate power, replace the affected Hotpoint-Ariston induction power module.
• Electrical supply: Have an electrician verify that the circuit supplying the cooktop is correctly rated and not shared with heavy loads that could cause voltage dips.
