An air fryer may not start or keep running if its basket, drawer or fry pot is not fully seated, the timer or cooking program has not been started, cooking is paused, or the controls have entered standby. Refit the cooking container and check the selected controls using your model’s steps below.
Is power connected and switched on?
For a corded appliance, check that the plug is fully inserted in a working power outlet and that the outlet is switched on. Set the appliance controls to off before reconnecting a loose plug; use the model’s start sequence after reconnecting.
Are the correct parts fitted and undamaged?
Switch off, disconnect external power and wait for all movement to stop before removing, refitting or cleaning parts or clearing food. Allow hot cooking parts to cool before handling them. Use only the parts intended for the exact model; never force a lock, bypass an interlock or open the base.
Check removable parts for cracks, broken tabs or other damage. Stop using a damaged detachable part and replace it before further use; cleaning or tightening will not repair it.
Has liquid entered the base, or is an electrical part damaged?
If there is liquid inside or under the base, or the cord, plug or base is damaged, stop using it, unplug it only if it is safe to do so, and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase). Do not try a cooling reset or open the base for this fault.
After completing the relevant checks below, leave the appliance off if normal operation has not returned and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).
If a check directs you to our team, or the appliance still will not start or keep running, see our warranty article.
