⚠ Safety note: This guide involves working with electricity. If you're not completely sure about every step, stop and call a licensed professional. Before you start, always switch off the power at the breaker or close the main water/gas valve.
1 Prepare a safe workspace
Unplug the cooktop from the outlet, turn off the water supply if present, and let any hot parts cool down. Get the manual for your exact model and prepare a dry work surface.

⚠ Warning: Don’t open any part with mains power, a capacitor, magnetron, heater, or cooling loop. A qualified service technician must diagnose those.
2 Identify the condition and cause
Write down the exact error code and model number before you turn it off. Check your manual to see if the code means a hot cooktop surface, a pot sensor issue, a ventilation problem, or a service fault.
3 Perform the key check
Remove all dishes and objects from the controls, dry the surface, and clear the ventilation openings underneath the cooktop.
4 Perform a reset or maintenance
After cooling down, reset only according to the manual. If the code comes back, the glass is cracked, or you smell burning, you need service.
? Tip: Take a photo of the starting condition and change only one thing at a time. That way you’ll easily see what actually fixed the problem.
5 Test the result
Reinstall all accessible parts and run a short supervised test. If you see leaks, sparks, a burning smell, or the protective cover popping off, turn it off right away and call for service.

When to call a professional: If the job involves changes to the electrical panel, the main gas line, or load-bearing walls/beams — or if you're not sure how it will turn out — this is not a DIY task. Hire a licensed professional.
