Solution: Check if the pan is too small. The zone requires a minimum pan diameter (approx. 12 cm). If not, try switching pans. If still cold, the heating element may be burnt – call a service technician.

Unlike induction, ceramic hobs heat up via radiant resistors beneath the glass. The Kotiliesi 600 K uses a 7-position rotary switch for each zone:

| Symbol | Setting | Best for | |--------|---------|-----------| | 0 | Off | – | | 1-2 | Low (Melting) | Butter, chocolate, sauces | | 3-4 | Simmer | Soups, stews, rice | | 5-6 | Medium | Pancakes, eggs, frying vegetables | | 7-8 | High (Boiling) | Pasta water, large pots | | 9 | Max/Boost | Rapid searing (but avoid empty pans) |

Pro tip: The residual heat indicator light will stay on after turning a zone off. Do not touch the zone until the light goes out.

| Problem | Likely Cause | Best Fix | | :--- | :--- | :--- | | Hard to light / Smoke in room | Cold flue or closed damper | Open flue damper. Preheat chimney by burning a rolled newspaper inside the stove with door closed. | | Glass turns completely black | Wet wood or too little secondary air | Open secondary air damper. Use wood with <20% humidity. | | Stove doesn't heat the room | Ash build up in bottom grate | Empty ash box and poke the grate holes clean. | | Rust spots on cast iron | Condensation from cold storage | Rub with fine steel wool, then coat with stove black polish or high-heat linseed oil. |
