E6 is displayed and the unit beeps, refusing to start a cooking program.

Safety first: Unplug the unit before manipulating internal switches or latches.

• Check basket insertion: Remove the cooking basket and reinsert it firmly until it clicks. Some Sage air fryers require the basket to be fully seated to close an internal switch.
• Inspect latch and rails: Examine the plastic latch tabs and side rails on the basket and housing. Look for cracks, deformation, or melted areas that prevent full engagement.
• Test the switch: With the unit unplugged and cover removed, locate the small microswitch or sensor near the basket cavity. Manually press the switch lever and listen for a distinct click. If there is no click or it feels loose, the switch may be faulty.
• Check continuity: Use a multimeter to test the switch contacts while pressing the actuator. Replace the switch if it does not open and close reliably.
• Adjust alignment: Slightly loosen the switch mounting screws and adjust its position so that the basket tab fully depresses it when inserted, then retighten.
