Quick check — and when it's not DIY
Before booking a repair, confirm the combi oven has power and rule out anything obvious — a tripped breaker, an unlatched door, a blocked vent. Also, unplug it for a minute and try again, since a simple reset clears more faults than people expect. Should that not clear it, if the basics check out, the fault is inside the control system or a sealed component, and diagnosing that safely takes a technician's tools and training.
