Fan-assisted modes do not heat properly; fan runs but temperature remains low

Safety first: Isolate the oven from mains and wait for it to cool.

• Access convection element: Remove the oven shelves and the rear internal panel inside the cavity (usually held by a few screws). This exposes the circular element around the fan.
• Visual check: Inspect the circular element for cracks, hot spots, or breaks in the sheath.
• Test resistance: From the rear of the oven, access the element terminals. Disconnect the wires and measure resistance; typical values are 20–50 Ω. Infinite resistance indicates a failed element.
• Inspect wiring and insulation: Ensure wires are not touching the fan blades and that insulation is intact. Replace any damaged wiring with high-temperature cable.
• Replace element if faulty: Remove the mounting screws holding the circular element, pull it out, and install a new genuine Ariston convection element. Refit the rear internal panel and ensure the fan spins freely.
• Test operation: Restore power and select a fan-assisted mode. The oven should reach set temperature without displaying the error.
