⚠️ SAFETY WARNING. This appliance is connected to the 230V mains. It is imperative to always unplug the appliance from the power outlet (or switch off the main circuit breaker) before any disassembly or thorough cleaning. As this is a pressure device, ensure it is completely cool and free of residual steam before touching valves or removing the lid, to avoid severe burns. If physical intervention proves complex, it is recommended to rely on a qualified technician. ReeFix provides this diagnosis EXCLUSIVELY for educational and informational purposes.
The "Burn" (or "OvHt") error on Instant Pot, with failure to pressurize and steam, primarily indicates a pneumatic seal problem (75% probability). Quick check: Inspect the Instant Pot silicone sealing ring of the lid: if worn, stretched, or improperly positioned, it is the most frequent cause. Also check the float valve with silicone gasket and the Instant Pot steam release valve to rule out obstructions. This often happens when the silicone loses elasticity or the pot is not perfectly clean. Perform the "Water Test" with 3 cups of clean water: if successful, the problem was related to the recipe (insufficient or too thick liquid, 20% probability). Cost: A new replacement gasket costs between €10 and €20.
Operational decision: If the gasket is worn or the valves are obstructed, you can resolve it yourself by thoroughly cleaning the components or replacing defective parts. If the "Water Test" fails and there are no obvious steam leaks, or if the error persists after replacement and cleaning, contact a technician to check the NTC temperature sensor or the electronic board (5% probability), with estimated labor costs between €30 and €50. In case of a serious electronic failure, consider replacing the device.
If you notice that the float valve does not rise or continues to leak steam without locking, the cause is often starch buildup or wear of its small silicone ring. Thoroughly cleaning the seat or replacing the rubber ring will immediately resolve the pressurization problem.
