F50 error; gas cooktop with electronic ignition fails to ignite or keeps sparking.

Safety: Turn off gas supply and disconnect power before servicing. Ensure the area is well ventilated if gas has been leaking.

• Dry the area: If the error occurred after cleaning or a spill, remove burner caps and allow the cooktop to dry completely for several hours. Use a hair dryer on low (not too close) to speed drying around electrodes.
• Inspect electrodes: Check each spark electrode for cracks, heavy buildup, or misalignment. Clean gently with a non‑abrasive pad and reposition so the tip is near the burner cap edge.
• Check wiring: Inspect ignition wires from the electrodes to the ignition module for burns or loose connections.
• Test ignition: Restore power and gas, then test each burner. If none spark, suspect the ignition module. If only one fails, suspect that electrode or wire.
• Replace parts: Replace defective electrodes or the ignition module as needed.
